Did you know that the tradition of decorating Christmas displays with Poinsettias started in Mexcio? They have a rich history in their native range, and the story of how they came to represent Christmas in the rest of North America is just as fascinating! Now with hundreds of varieties, they've come a long way in the plant world.

A few care tips for your Poinsettias at home:

  • It is extremely important to keep these warm climate plants away from drafts or temperature extremes while in your home.
  • Always bag them (preferably in paper) before transporting them to and from your car to help prevent shock!
  • Keep them well watered. If you leave them in their decorative foil, either remove it when watering or  put a couple holes in the bottom to allow for drainage. Use a drip tray under them to keep your table or floor dry.

The Bayberry Candle

Lighting bayberry candles around the holidays has become a cherished tradition.  It’s said that if you burn a bayberry candle on Christmas Eve or New Year’s Eve, it will bring good fortune into the new year.  This tradition can be traced back to colonial America. 

Bayberry candles are made from a waxy residue released from boiled fruit of the bayberry shrub. These were one of the first waxes made from a material other than tallow (animal fat). They were appreciated for their pleasant scent.

For native gardens, the Northern Bayberry, Myrica pensylvanica, makes a great addition to be appreciated by people and wildlife.

Forcing Bulbs Indoors

Forcing spring bulbs to bloom indoors is a fun way to bring some spring cheer into your home during the dark, cold days of winter.  With a few key steps you can successfully grow spring bulbs in your home.  

Timing and temperature will be the key factors to consider when forcing bulbs in your home. Different types of plants may have different needs, so knowing the species will be key in identifying conditions needed to ensure success!

The Winterberry holly (Ilex verticillata) is a native shrub with multi-season interest. It is a deciduous holly, meaning it loses its leaves in the winter, but when it does so the berries hold tight creating a vibrant and colorful display in the dead of winter!

Cultivars can be found with red, orange, and yellow berries to add more variation to the garden. Plus the berries are a great food source for native birds and wildlife.


Word from the WiSE

Christmas Cactus Schlumbergera x buckleyi

This month, UConn’s Women in Soil Ecology bring you a word on an indoor holiday favorite: Schlumbergera x buckleyi, otherwise known as Christmas cactus.

Did you know most Schlumbergera are epiphytes? In their native rainforest environment, they can be found growing high on the trunks of trees. Epiphytes are fascinating plants – while they use other plants for growth support, they are not parasites.

Without direct access to nutrients from the soil or other plants, many have evolved to grow slowly, absorb nitrogen from the atmosphere, and some form relationships with microbes and fungi on their roots which help them take up nutrients. Domesticated into pots, the Schlumbergera we see filling garden centers and homes every holiday season are a mixture of two wild-types and Schlumbergera x buckleyi, a hybrid cross first bred in England in the mid-1800s.

One of the most appealing features of Christmas cactus are the flowers. Pollinated by hummingbirds in the wild, the blooms can be white, orange, pink, or red.

Home gardeners can try and force their Christmas cactus to bloom by placing it in a cool location where it receives 13 hours of continuous darkness per day for several weeks. In the Northern hemisphere, this could be achieved by placing the plant in a North, west, or east-facing window.

After the holiday season, be sure to give your Christmas cactus plenty of indirect sunlight, water thoroughly once the soil is dry, and fertilize occasionally with an all-purpose low-analysis fertilizer, like a 10-10-10.

                  December Gardening Tips

                          • Mark perennials and bulbs before they become covered in snow to help you identify plants in early spring.
                          • Holiday plants, including amaryllis, mistletoe, and yew are toxic and should be kept away from children and pets. Contact Poison Control at 1-800-222-1222 immediately if you suspect a problem.
                          • Decorative foil around the roots of holiday plants can hold water and drown them. Either remove it when you water, or poke drainage holes in the foil and use a saucer.
                          • Finish the cleanup of the vegetable garden or beds, removing all plant debris
                          • Asian lady beetles and Brown marmorated stink bugs may enter the home to overwinter. Use weather stripping or caulking to keep them out.
                          • Check vegetables that you have in storage. Sort out any that show signs of disease and dispose of them.
                          • Turn compost piles one more time before they freeze for the winter.
                          • Avoid using salt to melt ice on driveways and sidewalks which may end up on the lawn, when possible use sand or kitty litter. This will help prevent salt damage to plant roots.
                          • If you have a real Christmas tree, recycle it after the holidays are through. Cut off branches and use as insulation over perennials. In spring, chip or shred branches to create mulch or add to the compost pile.
                          • Replace the plants in hanging baskets, containers, and window boxes with evergreen boughs, berries and pinecones.
                          • Be sure to keep bird feeders stocked with seed and suet for the winter months.

                          Happy Holidays!

                          Holiday Gifts for Gardeners

                          Let the holiday shopping begin! Compared to many family members and friends, buying a gift for the gardener in your life is a breeze. Lots of great possibilities and there’s always the option of a gift certificate to their favorite local garden center. These are just some of my personal suggestions.

                          With long, dark days settling in, reading is a great winter sport. I’m partial to whodunnits and might curl up with The Garden Party by Marty Wingate or The Garden Club Murder by Amy Patricia Meade. For non-fiction readers, especially those longing for greater self-sustainability, perhaps Small-Scale Homesteading by Michelle Bruhn and Stephanie Thurow might be an informative resource when just starting out. With all the calls we get about vegetable problems, two books by Susan Mulvihill; The Vegetable Garden Pest Handbook and The Vegetable Garden Problem Solver offer up lots of great photographs and least toxic controls for a myriad of insects, diseases and other pest problems. Of course, you can also call us at the Center for assistance.

                          Gardening magazines still offer excellent articles, advice and inspiration. A subscription to the Connecticut Gardener should be in every CT gardener’s mailbox or inbox. Fine Gardening is also CT based and fills our head with amazing plant information and truly inspiring gardens. I’ll also admit to a subscription to both Horticulture and The American Gardener.

                          Working in the garden often brings me to my knees and when that up close and personal, I find there are 2 tools always in my bucket. First is a Cobra head weeder, crafted in Wisconsin last I looked. This curved-headed tool can be used for weeding, thinning, making seed rows, digging in little seedlings and whatever other use you can come up with; a multi-tasking tool that is long-lasting and affordable. My deluxe soil knife features a smooth, sharp side and a serrated side with inch measurements, useful when planting. I find it does a nice job dispatching both annoying roots and jumping worms. When deployed on the ground, those larger, oval-shaped kneelers are tough and functional.

                          In my most recent issue of The American Gardener, there is a Craftsman 54-inch wood-handle action hoe that I would like to try so I can weed standing up. It works with a manual push-pull action but might be just the thing us older gardeners need.

                          While I have 2 different types of pruners that are great for stems from about a half to one inch in diameter, I can use help on the opposite extremes. Last year my sister got me a hand-held mini-chainsaw and it is wonderful for removing 1 to 3 inch or so stems or branches. It’s really made pruning much easier. On the other end of the spectrum, a pair of horticultural scissors with long blades treated to resist rust would be great for harvesting or deadheading cut flowers as well as indoor houseplant grooming.

                          For years, I have placed picked vegetables, whether peppers, carrots or chard into those attractive wicker baskets. Recently, I was given one of those garden trugs made out of recycled plastic that had holes on the bottom so I could gather up my harvest and then hose the soil off in the same container. There are several trugs on the market including those made of wood and wire mesh. They do make cleaning your vegetables a lot easier than doing it at the kitchen sink.

                          Gardeners go through gloves and despite what the ads say, if a pair lasts me a season, I’m lucky. They are always needed and appreciated, and you can’t go wrong gifting these to a gardener. For those with a lot of roses, consider purchasing a pair of rose gauntlets so their arms won’t get all scratched up when pruning.

                          Indoor gardeners might appreciate watering cans with long spouts that dispense water slowly, attractive cache pots, houseplant fertilizers, cork plant coasters or misters. Bird lovers may enjoy feeders, bird baths, bird houses or seed and suet for their fine-feathered friends.

                          There are many types of garden ornaments to present to your plant loving friends and family. Plus, tis the season for holiday plants – poinsettias, holiday cacti, amaryllis, frosty ferns are just a few of the selections that your gardener recipient might enjoy. With all these choices, the gardener on your gift list is sure to be pleased.

                          For your gardening questions, feel free to contact us, toll-free, at the UConn Home & Garden Education Center at (877) 486-6271, visit our website at www.homegarden.cahnr.uconn.edu or contact your local Cooperative Extension center.

                          CRIS Radio: Focal Point 11/25/2024

                          Heather Zidack from the UConn Home & Garden Education Center talks to host, Stephen Thal, about common holiday plants, houseplant care, and indoor winter gardening.

                          Transcript

                          00:00:01 Stephen Thal 

                          Hi and welcome to another segment on Focal Point. I'm Stephen Thal, and I'll be your host for today's program. Today we have a former guest who was on in the spring to help us about plants and from the UConn plant and science center out at Storrs. So, welcome back, Heather Zidack. It's glad to have you back. 

                          00:00:25 Heather Zidack 

                          Thank you. I'm excited to be back. 

                          00:00:27 Stephen Thal 

                          Yeah, we can learn more about what's going on because apparently, we have some sort of drought. We've had some fires around the state. And I'm sure people are unloading a lot of questions for you guys up there at Storrs. 

                          00:00:42 Heather Zidack 

                          Yes, we're getting a lot of questions right now about the weather concerns and people are calling because their plants are in distress. Right now it's a really good time to make sure that you are watering especially for new plants that are getting established. Anything that you planted this year, you want to keep watering until the ground freezes. So we still got a little bit of a way to go with that.  Other plants that are starting to drop their leaves and showing signs of stress. Some of those we're telling our clients to kind of just wait until next spring and see how they leaf out next year because they might have just decided to shut down a little bit early with the drought. But we really won't know until next spring when they're growing, whether it's a big problem or just a little hiccup on the in the road. 

                          00:01:36 Stephen Thal 

                          OK, so one of the things we'll be talking about is house plants inside. They're being moved inside. They said they had enough of outside. Gotta get in before the cold. 

                          00:01:50 Heather Zidack 

                          Yes! So right now is really good time. Most people have started to bring their house plants in what we're looking for and what we guide is 50° at night or lower is that threshold. So once we hit 50° at night consistently, you wanna start bringing your plants in. There are some that will take a little bit more, you know, a little bit of a higher temperature, they're a little more sensitive to the cold. There are some that will tolerate some lower temperatures, but that 50° mark is really the best guideline.  

                          And so we, we tell people to bring them in and you want to kind of bring them in slow. So you wanna start with bringing them into if you have a mud room or a garage, or a three season room, or even somewhere like that's a little bit more protected than wherever your outdoor plants were in the summer to help them adjust to the temperatures inside. So they adjust to the lower light provided by maybe an overhang or something to that nature. And then they slowly move them in. 

                          You want to put them into a place that's sunny. If they need sun. If you've had these plans for some time, you may have an area established already that they go to. If it's your first time giving this a try, you will probably know if they were in full sun when they were outside. They're going to need a really sunny place when they're inside as well. 

                          And when you bring them in you want to avoid putting them in any locations that have temperature extremes. So near drafts, near heat vents, near entryways anywhere that the temperature we can get, a gust of wind come in, or a gust from when the heat kicks on. Those are all things that the plants are going to not enjoy as much as we would, you know, you go in from the grocery store, you get that big gust of warm air. The plants may not like that as much. So it's the same kind of thought for them. 

                          00:03:57 Stephen Thal 

                          Now, well, many of these plants are coming in, are showing growth again? 

                          00:04:03 Heather Zidack 

                          Some of them do. What's really happening, and it's actually interesting, is because we've had these drought conditions, plants bringing them in right now, they may have a little bursting growth. You may notice the opposite where they're going to start having a little bit of a decline. Plant stress is always- They always speak in one way, and that's to either wilt or drop leaves, no matter what's going on. So you will see that they may have a little bit of a temper tantrum as you move them, but that's totally normal and just keep to doing what you've been doing with them, make sure your watering is consistent, make sure that they're in the right spot. 

                          And it really depends on what kind of house plant you have. So some of them will slow growth and they'll kind of just stay the course while they're indoors. They will stay green. They'll stay upright. It'll look like they're almost like an artificial plant where it's like they haven't done anything for a while. 

                          Some will go dormant. So, like I said, they'll drop their leaves. They'll look like sticks and pots. They won't look very good at all.  

                          You'll feel like you don't have a green thumb anymore. That is also natural, and some plants like hibiscus have a cycle where some years they will be in flower, and they will do really well. And then some years they will have that dormant period. So, it can be a very wide range. 

                          If you're ever unsure, go ahead and scratch your thumbnail into the stem of the plant. If you feel very, if it feels very dry and it breaks easy like a stick, that's probably a red flag. You want to feel some kind of fleshy texture. You want it to feel a little bit soft, not mushy, but a little bit so that you feel your nail digging into that tissue you want to. If you're able to get a closer look, you want to look for signs of green and feel some moisture. Those are all signs that even though there's not a leaf on it, it is still alive, and it will come back in the spring. 

                          You know, so like I said, if anything is other than that where it's it snaps easy or it's incredibly mushy when you push your finger into it to it those are all signs that there could be something bigger going on and then you really have to take a look and see if there's disease or other things that are causing stress to the plant at that time. 

                          00:06:36 Stephen Thal

                          And that doesn't mean necessarily throw a lot of water at it?

                          00:06:41 Heather Zidack 

                          Correct. That's actually something that happens a lot. People will tend to over love their plants and I'm even guilty of it myself. If there's a plant in my home that I haven't watered in a week or two, I will put a little bit extra just to keep it going and that's something that we really want to avoid doing. You want to make sure that you're always consistent when you're watering your plants. Feel the soil with your fingers. If it feels-you want to poke your finger in a couple inches-If it feels moist in that depth, you're good. If it feels like it's dry or sandy or scratchy. It's going to be something that you need to add water to at that time also. 

                           That's the caveat of knowing what kind of plant you have. For example, Cactus can actually survive those drier temperatures, right? So, you want to know what you're taking care of, what it needs and be able to kind of check that. Water regularly. Too much moisture in the soil is going to lead to issues like root rot, pests, those fungus gnats that are everywhere. Those are teeny, teeny, teeny tiny black gnats that sometimes we see in the winter time. Those are actually not even feeding on plants. They're just feeding on the decaying root material. And so that's a sign that there's too much moisture. 

                          You can mist your plants, but it's not always necessary. You need to just know what you have and research the specific needs of the species of plant you have. 

                          00:08:17 Stephen Thal

                          And where would you go to find that information from a flower shop or?

                          00:08:23 Heather Zidack 

                          You can. Usually when you purchase the plant, it will come with some kind of tag. 

                          It does depend on where you're looking, but usually they have some kind of tag that at least has a common name on it, so that is the very the colloquial name. So, a common name is like a fiddle leaf fig or a Benjamin fig, whereas the botanical name is going to say Ficus benjamina for a Benjamin Fig and what you're gonna do with that information is then you would, you could call our office at home and garden and we can help you get some information on how to take care of it or you can go ahead and do some of that research yourself to see what those plants are going to need. Really, you need just the name. The common name is good. The botanical name, so it's usually on on those little labels in italics. That's even better. And if you're not sure, we can always take a look at some pictures and try to help you out as well. 

                          00:09:23 Stephen Thal 

                          Why don't you give them your phone number since you mentioned it mentioned that they can call you. 

                          00:09:29 Heather Zidack 

                          Yeah, sure. So, at the UConn Home and Garden Center, you can give us a call. Our number is 860-486-6271. Again, that's 860-486-6271. 

                          00:09:49 Stephen Thal 

                          What about house plants? Do we have a sort of categories of house plants we can review? 

                          00:09:55 Heather Zidack 

                          Yeah. So I actually have a list that I had ready for us today to talk about house plants that are going to be common now that we're going to be moving into the holiday season. We're already getting ready to talk about Thanksgiving and Christmas and seeing the decorations in the stores. So I thought it would be a good idea to bring up some of those plants that people might be seeing at this time of year. 

                          00:10:18 Stephen Thal 

                          OK, which one would you like to start with? 

                          00:10:21 Heather Zidack 

                          So the first one that I have is called an amaryllis, that is given as a bulb as gifts at Christmas I you know, I've gotten those for Christmas gifts before you see them in displays and windows.  

                          These are the kind that have a very thick large single stem that emerges from a bulb that's probably the size of your fist. The larger the bulb, the more flowers and the more stalks you're going to get, right? Those flowers at the top are very large. Those are probably about the size of your open palm for a lot of these species, they have 6 petals. On those flowers. It's kind of an organization of three and three yo make that cluster. Tou can have two or more flowers in a cluster, they're very, very big, very vibrant. They're very attention catching and you see variants of red, pink, white, all of those colors and solids, stripes and everything in between.  

                          It is something that if you have a green thumb and you wanna start them yourself. You want to start them in early to mid November and you'll make sure that you'll have blooms for the holidays. You just use regular potting soil. You don't use dirt or anything, you use potting soil and you keep the soil moist and you keep it in a sunny window and from there that plant will come out of the bulb. You'll see the green stalk and the green leaves first and then up at the very top, you'll get that flower to bloom right at the holidays. So that one's really, really cool. 

                          00:12:02 Stephen Thal

                          Do you have a second one that's common?

                          00:12:06 Heather Zidack 

                          Yeah. The next one, we'll talk about the holiday cactus. There are a bunch of different holiday cactuses and this one I like to talk about because we have a Thanksgiving cactus. We have a Christmas cactus and there's actually an Easter cactus as well. They're all house plants that people have. 

                          The common misconception with these guys is that their bloom time is the only thing that identifies them. So, your Thanksgiving cactus is going to bloom in November. Your Christmas cactus will bloom in December, and your Easter cactus sometime in the spring. 

                          The actual difference between the three is the shape of their flowers is slightly different, and the shape of their leaves is different. When you look close. The Thanksgiving cactus has deeper lobes or indents into the leaf. Right, it looks sharper. It almost looks like it has a pair of cat ears on the top of the leaf that's emerging.  

                          The Christmas cactus is going to be similar to the Thanksgiving cactus, but it's a totally flat or square top to that leaf, so there's no cat ears on it. It's just totally flat. 

                          The Easter cactus is round. So that leaf is rounded at the top and the colors of all three of them will vary. So you'll have your Reds and your whites and your pinks. I've seen some in like salmony orange colors and with all three of them, you can purchase them from the store, or you can start them from cuttings. And what you can do is you can actually take a small branch. Dip it in. They have a product called rooting powder. 

                          And put it in some sandy potting soil and it should be able to produce some roots for you. So they're really easy. If you want to get into plant propagation. If you want to have something that's a low water need to take care of, these guys are really good because they are in the cactus family and they're just very colorful and very seasonal. Depending on what time of year they bloom. 

                          With the three, the time of year, the light can actually affect when they bloom or not too, so that can be a really interesting thing. So always look for the shape of those leaves. 

                          00:14:25 Heather Zidack 

                          Do you want to hear the one I have next? 

                          00:14:27 Stephen Thal 

                          Sure 

                          00:14:28 Heather Zidack 

                          All right. So then I have a plant called paperwhites. These are tiny. They are actually Narcissus bulbs, which is a relative of the daffodil. So if you're familiar with the daffodil shape that has those petals that are kind of like a wide open starburst with that circular set of petals in the middle. That's what it looks like, but it's on a very small star shaped scale, so they have tiny White Star shaped flowers, upright green foliage and stems. They're very delicate. They're very leafy looking. 

                          Many varieties are fragrant and what you can do with them is you can start your bulbs between September and November indoors, and you'll get flowers during the holiday season and winter months.  

                          Cooler temperatures help them root for the first few weeks, so if you're putting them in two pots yourself, you want to keep them at 50 to 60° to help them develop their roots in those first couple of weeks. 

                          And then temperatures above 70 are going to cause them to kind of flop over. They're not going to hold their shape as well. So if they get too warm, they can also throw a little bit of a fit about it. And so they will be much happier if you're able to stake them up if the room is too warm and they start to do that, flopping over, they like the cooler 50 to 60 kind of temperature for them, so that's something to keep in mind. 

                          00:15:57 Stephen Thal 

                          Yeah. What kind of pots do you use? I know some people use clay pots. Some people use plastic ones or other types of. 

                          00:16:04 Heather Zidack 

                          Really, the pot material isn't the important thing. What you really want to make sure that you have is the right size. So for paperwhites, you would probably want maybe a six inch pot or like a geranium pot to put your bulbs into. You want to make sure that whenever you have for house plants-and this is even stuff that you bring in-You want to have your pot be a little bit wider than your root ball. So once the roots start getting too expansive, you're going to have what's called a root bound plant. And so it's kind of going to be outgrowing itself, kind of like when we outgrow our shoes, when we're kids, right. So you want to put a new pot there. 

                          You want it to be just an inch or two bigger than that root ball so that it has enough room to continue growing. That's really what you want to pay attention to more than the material. 

                          00:17:05 Heather Zidack 

                          And then the last one that I have is poinsettias. Do you want me? To go into that one. 

                          00:17:08 Stephen Thal  

                          Sure. 

                          00:17:08 Heather Zidack 

                           All right. So for pointsettia is for the holiday. This is our traditional holiday plant that we have. What's really cool about these guys is that they were discovered in Mexico where it actually grows natively. The native poinsettia doesn't look at like anything that we know from what we've seen in stores. It's actually tall, it's a little bit what we call leggy. So it actually spreads out. 

                          You know, and it's very wild looking and it's more shrub like it. It is a very different plant altogether. It was something from Aztec culture. They had a lot of symbolism behind this plant where it represented purity and new life earned by warriors who had died in battle. 

                          It was used for dyes and other products and then it didn't come to the US until the 18 hundreds and then it started to become a a holiday staple over the years. There's a lot of people that can go out, and purchase them.  

                          The growers start those plants in August or September, sometimes even earlier. We're still all in summer mode thinking about getting those last few days at the beach, and they're already putting these points that is in the pots. So it's something that is it takes a long time to grow. They love heat and they love warmth. So that's something to keep in mind when you have them in your house.  

                          They come in tons of varieties and colors now and they've really done a lot of breeding projects to get them to change from what they originally were with that wild native plant. 

                          And so the new colors have all sorts of different stripes, splashes, solid colors, Reds, whites, pinks and everything in between. There are ones that are blue, and some of those can actually be painted. You have to kind of take a look and see real close if they're painted or if it's a a color that's true from actual breeding but you'll be able to tell if you look close. 

                          00:19:11 Stephen Thal 

                          Hmm. Wow. 

                          00:19:13 Heather Zidack 

                          They're really cool. 

                          00:19:13 Stephen Thal 

                          Yeah. Yeah, I would agree with you. Yeah, yeah. 

                          00:19:18 Heather Zidack 

                          Yeah. 

                          00:19:18 Stephen Thal 

                          What people tell me they are. Yep, you're right. 

                          00:19:22 Heather Zidack 

                          Yep. And they have. They have a really, really nice history from them too. So it's always cool to see what plants start as and what they end up becoming. That's a, that's a really cool field to look at with plant breeding and how plants have changed over time. 

                          00:19:40 Stephen Thal 

                          Yeah. OK. Well, these are exciting. And the one day they get all nice colors and and they also have it used to be used for dyes. That's interesting. 

                          00:19:50 Heather Zidack 

                          Yeah, they used to use the color they they used the petals for dyes and all sorts of different uses when they would use the native plant. 

                          00:20:03 Stephen Thal 

                          And I bet you the fragrance is pretty nice. 

                          00:20:06 Heather Zidack 

                          They actually the ones that we have now don't have too much fragrance. I don't know about the wild or the native ones, how fragrant they were. But the other thing that's really interesting about poinsettias is the fact that they have their flowers and what we know to be their flowers are actually the tiny itty bitty yellow spots in the center of the plant. So if you ever look at a whole Poinsettia plant and you see the little tiny yellow pieces in the middle, those are the actual flowers. What we see is changing colors and different petals and things like that is actually called a bract, which is a modified leaf. 

                          And so, they're all leaves that have changed color. So that's another really cool fun fact about them. 

                          00:20:56 Stephen Thal 

                          Yeah, yeah. No wonder people flock to the poinsettias and they're around the holidays a lot. 

                          00:21:05 Heather Zidack 

                          They're very popular. 

                          00:21:06 Stephen Thal 

                          Yeah, also about. Any what about poison plants? We know sometimes during the holiday season there are some plants that children, adults and animals should be cautious. 

                          00:21:21 Heather Zidack 

                          Yeah. So, one of the things that we tell our clients is that our office and with the home and Garden Center, we can identify a plant for them to tell them what it is. And we can say that is a poinsettia, for example, right? 

                          Other professionals need to be the ones to deem it toxic and give you those warnings. So the best advice that I can give to you is to do your research before purchasing any plant. You want to kind of like I talked about with the house plants before. Know the species of what you're purchasing and that'll help you to determine whether it's toxic for people, for pets, for anything like that. There is a really good resource from the ASPCA. They have a database of plants that are toxic to domestic animals, and they have a 24 emergency hotline, a 24 hour emergency hotline. Now that's for pets. I do have that number. Would you like me to share that with you? 

                          00:22:22 Stephen Thal 

                          Yes, please. 

                          00:22:23 Heather Zidack 

                          OK, so that is 1-888-426-4435 again, that's 1-888-426-4435. 

                          00:22:41 Heather Zidack 

                          Now on the people side of things, when you're looking at plants that could be toxic again, I can give you the identity of what that plant is, but then we would refer people to the Connecticut Poison Control Center for human toxicity. And I have that number as well. Would you like that? 

                          00:23:00 Stephen Thal 

                          Yes, please. 

                          00:23:01 Heather Zidack 

                          Alright, so that number is 1-800-222-1222. Again, that's 1-800-222-1222. 

                          00:23:19 Heather Zidack 

                          And any plants that you have done your research on and found that they could be toxic house plants, anything like that, you want to make sure that they're kept out of reach of children and pets-if you're going to bring them into the home. If you do that background homework and figure out if it's toxic to your pets or children or whatever you, you know, are concerned about the toxicity of. You can also just not bring them into the home. So the best thing to do is to know what the plant is, have those emergency numbers on hand. 

                          And keep anything out of reach or just don't bring it home at all. If you have any concerns. 

                          00:24:01 Stephen Thal 

                          OK, this is Stephen Thal with another segment on focal point and we were speaking with Heather from the UConn plant and Science Center up at stores, Connecticut. We have to remember many years ago, as I remember, as I recall from history is that that was one of the first universities in Connecticut to start as an agricultural college, didn't it? 

                          00:24:27 Heather Zidack 

                          Yes, we have a very deep history here at the university and the College of AG, which is now the College of Agriculture, Health and Natural Resources. We call ourselves CAHNR for short C-A-H-N-R. That college was one of the first ones started here at the University of Connecticut as well. 

                          00:24:48 Stephen Thal

                          What are some other plants that you'd like to end the program with?

                          00:24:57 Heather Zidack 

                          I think one thing that we could talk about real quick is growing herbs indoors because that's something that a lot of people can do. You can still grow your herbs right now whether you want to dig up the herbs that you have in your garden and bring them inside. 

                          And get a whole grow light operation and everything else, which is what I do because I am a very, very intense gardener at home. I bring my plants in. Or you can start herbs. Herbs are one of the easiest things that you can grow on your window sill indoors. It's very easy to start and restart and regrow them from time to time. 

                          Whenever you start them, you can start them from seed to anytime and many of them like basil for example, is really good. You can just put a sprig of basil in a jar of water and it will actually send out some roots and you can put that in a a pot of potting soil and grow your basil from that as well. 

                          So you can do that. Most herbs do well by a sunny window. They are used for culinary purposes. It's also a really great fragrance in the wintertime. It's really nice to have fresh herbs all year round and it's easy to rotate them. Like I said, if anything happens-Disease or you get bugs, or you get anything like that-It's really easy to just kind of let them go and start fresh with new herbs. If you're growing herbs. 

                          00:26:29 Stephen Thal 

                          Now, do you- 

                          00:26:31 Heather Zidack 

                          Oh, go ahead. 

                          00:26:32 Stephen Thal 

                          Do you need a lot of light for these herbs? Put them in a lot of light area. 

                          00:26:37 Heather Zidack 

                          They tend to need a sunny window, herbs. The nice thing is that because they aren't producing flowers, they don't need as much sunlight and as much energy as some of the other house plants that we were talking about. So they do need a sunny window, but they can actually adapt pretty well to other conditions as well. 

                          00:27:00 Stephen Thal

                          UM, that's wonderful. Herbs and anything else you can grow at home.

                          00:27:08 Heather Zidack 

                          The other, the last thing with the herbs, that's really cool that we're seeing is a trend right now is that Rosemary plants are being used as mini indoor Christmas trees. And so people are purchasing Rosemary plants that are shaped to be like a Christmas tree. 

                          Stephen Thal  

                          Yeah 

                          Heather Zidack 

                          They decorate them for the holiday and then they end up having them throughout the rest of the winter for a-they can use it for the culinary purposes. They're fragrant. They're really pretty. So that's that's something that we're seeing is a new trend right now. 

                          00:27:40 Stephen Thal 

                          Right. And so they don't have to throw the tree out. 

                          00:27:44 Heather Zidack 

                          Right, exactly. They can keep it and they can go from there, yeah. 

                          00:27:45 Stephen Thal 

                          Recycling 

                          00:27:48 Stephen Thal 

                          Very good. OK. Heather, we want to thank you for a great job and a great wealth of information. We hope that people will take notes and if you want to leave your phone number one more time to regarding information or how they can assist you, how they can you can assist them. 

                          00:28:06 Heather Zidack 

                          Yeah. So if anybody has any questions about gardening, plants or anything that we talked about today, we we are here Monday through Friday, 8:00 to 4:00 give us a call. The number here is 860-486-6271. Again, that's 860-486-6271 

                          00:28:28 Stephen Thal

                          We want to thank you very much for your information and we hope that the people online will find this helpful and also not only ask your question but maybe go online and show you the pictures on your computers, right. You might be able to do that.

                          00:28:46 Heather Zidack 

                          Yes, that would be fantastic. We can do a lot with pictures, and we can help people with their gardening projects and questions that they have. 

                          00:28:55 Stephen Thal 

                          OK well, wishing you and your family and the school a happy, safe holiday. I know this Thanksgiving’s not too far around the corner. 

                          00:29:06 Heather Zidack 

                          Yes, thank you. You too. 

                          00:29:07 Stephen Thal 

                          Take care and stay well and thanks for coming back and give us a call in the spring so we can get you on again. 

                          00:29:08 Heather Zidack

                          Poinsettias: The Story of a Holiday Treasure

                          Poinsettias: The Story of a Holiday Treasure

                          It just isn’t the holiday season without a poinsettia. We adorn homes, churches, and other public spaces with them at this time of year. Their bold color and striking presence are hard to miss.  With a story as spectacular as their seasonal color, the poinsettia is a plant to be treasured.

                          Poinsettias have a rich history and culture. While we associate them with the coldest time of year here in the Northeast, they actually come from a much warmer climate! Known as Cuetlaxochitl in their native region of Mexico, they were cultivated and used by indigenous peoples for medicines, dyes, and decorations. In Aztec culture, the Cuetlaxochitl held cultural significance as a symbol of purity and were also used to symbolize a new life earned by warriors who had died in battle. The Mayans called this plant k'alul wits. Many traditional uses for k’alul wits are still practiced by the Téenek people in southeastern Mexico, today.

                          Their association with the Christmas holiday started when Franciscan monks in Mexico began to use their bright red and green foliage to decorate nativity scenes. It became known as la flor de Nochebuena, translating to “the Christmas Eve flower.” It was brought to the United States by Joel Roberts Poinsett, the first U.S. minister to Mexico, in 1825. Poinsett was a man of many talents, having a career in politics, a passion for science, and an enthusiasm for agriculture. Through continuous plant breeding and developments, there are now hundreds of varieties of poinsettia.

                          Contrary to popular belief, poinsettia flowers are small and barely noticeable. The insignificant yellow flowers are surrounded by stunning, colorful bracts. Bracts are not flower petals, but rather, specialized leaves. The bracts of a poinsettia change color when daylight hours begin to shorten. Breeders have developed poinsettias that have bracts of various shapes, textures, and colors. Some are variegated or have speckles of color on them. These cultivated varieties (cultivars) are quite different from the straight species, Euphorbia pulcherrima, in its native environment, where it can grow over 10 feet tall, is semi-evergreen, and can sometimes grow a bit scraggly.

                          Greenhouses start poinsettia production as early as July. Tiny plugs get put into their pots while we’re all still soaking up the summer sun. (It makes sense when you remember that they’re originally from Mexico!) They grow as little green plants through the rest of summer and autumn. The fall equinox will naturally trigger these plants to change color, however, growers can manipulate their greenhouses to create ideal darkness/brightness to help time the coloring of their plants for holiday sales.

                          If you’ve got a green thumb and are trying to get a previous years’ poinsettia to “reflower,” simulating this dark period with an opaque container, paper bag, or moving the plant into a closet or dark location for 14-16 hours a day can do the trick! Make sure they’re receiving 8 hours of bright, direct light, and not a ray more! After about 4 weeks of these conditions, most poinsettias can go back to their life with your other houseplants, as normal, and you should see a change in color.

                          Shopping for a new poinsettia as a gift or decoration this year? Always shop for a plant that is brightly colored and has tight (tiny yellow) flowers that aren't already going by. Select a plant that has evenly moist soil, and a nice shape that doesn’t appear to have been crowded for too long. Here in Connecticut, make sure that your florist, grocer, or grower packages the poinsettia for you to help protect it from cold winds while transporting it to and from your car. When you get it home keep it away from entryways, drafts, fireplaces, or heating vents, and keep it in a room that is between 60° and 70°F. Water your poinsettia when the soil begins to dry out in the pot and enjoy the holiday season.

                          Whether you’re reviving an old poinsettia, shopping for a new one, or deciding that artificial is the best choice for your home this year, take the time to recognize the special journey these plants have taken to become such a treasure and staple in our holiday celebrations. There truly isn’t anything quite like it!

                          Berry Good Pick for Winter Interest

                          Looking for a splash of color in your yard amid winter’s dreary landscape? Check out one or more of the many winterberry (Ilex verticillata) cultivars. This deciduous member of the holly family sports bright, shiny red berries from early fall through late winter. Branches may be cut and used in holiday arrangements.

                          Winterberry can be found growing throughout eastern North America from Canada down along the east coast and west to Texas. Look for the brilliant red berries when driving past marshy areas in particular. While winterberry will grow in well-drained soil, it is a great candidate for areas that stay moist and aren’t particularly well drained. These plants naturally occur in forested wetlands as well as along the banks of streams, ponds or other water sources.

                          There are several factors to consider when selecting a winterberry bush for your yard. One of the most important is the mature size of the plant. Cultivars are available that vary from dwarf, 4-foot, compact plants to 15-foot, more rangy specimens. ‘Red Sprite’ and ‘Berry Poppins’ are two red-berried, compact cultivars. ‘Winter Red’ and ‘Sparkleberry’ typically top 10 feet. Check out suggested cultivars for Connecticut with the UConn Plant Database (https://plantdatabase.uconn.edu/). While initially slow growing, winterberries may eventually form clumps through suckering and depending on the cultivars, may form dense stands if allowed.

                          The berries on most cultivars are a brilliant red. There are, however, some that have gold or orange fruits. ‘Goldfinch’ boasts golden yellow berries while both ‘Aurantiaca’ and ‘Afterglow’ offer delightful orangey fruit.

                          Do realize that plants are dioecious, meaning that individual plants may be male or female. Only the female plants produce berries. The male plants supply the pollen to fertilize the female’s flowers so that berries are produced. One male plant can fertilize at least 10 females if located within 50 feet or closer. Look at tags so a compatible male cultivar is chosen. Appropriate pollinators should be listed on nursery tags.

                          Unless plants are in bloom or have berries, it is not possible to tell males from females, but they should be marked on their tags at the nursery. When in bloom, the female flowers have tiny green immature berries in the center while the males have fluffy, yellow, pollen-bearing anthers. Occasionally the female flowers have non-pollen bearing anthers, probably effective is luring pollinators to fertilize their flowers. Although not common in Connecticut, one native species of cellophane bee, Colletes banksi, is a specialized pollinator of winterberry.

                          Winterberries do best in full sun to partial shade. The shadier the site they are grown in, the fewer blossoms and berries they will produce. Being native New Englanders, they prefer acidic soils rich in organic matter. If your soil pH is between 5 to 6.5, plants should happily grow. Once plants are established, only minimal fertilization is usually required. For the first few years, about a cup of a complete organic or synthetic fertilizer could be lightly worked into the soil surrounding the plant each spring.

                          Plants can be used in foundation plantings, as a hedge, in rain gardens and when setting up areas attractive to wildlife. Not only are pollinators attracted to the flowers but over 48 species of birds feed on the berries, typically after they soften following periods of freezing and thawing.

                          Pruning can be tricky and is best kept to a minimum so selecting the right sized cultivar for your particular site is crucial. Winterberries have an upright growth habit but may sucker. They bloom on old wood meaning the flower buds that open in the spring were formed last fall. If grown as a multi-stemmed shrub, a few stems can be removed if plants seem crowded.

                          Complaints about little or no berry production may be due to lack of a male pollinator, too much shade, young plants that have not established a good root system, improper pruning or excessively dry conditions. In general, winterberries are rewarding, easy to grow shrubs that make quite the impact when little else in the landscape stands out.

                          The Fall Invasion of the Asian Lady Beetle

                          By Marie Woodward, UConn Home & Garden Education Center

                          As the leaves change color and the weather turns colder, many people look forward to the beauty and coziness of autumn. However, one uninvited guest often accompanies the season: the Asian lady beetle. This insect, scientifically known as Harmonia axyridis, can be a nuisance to homeowners as it seeks shelter in warm buildings during the fall months.

                          The Asian lady beetle is native to eastern Asia but was introduced to the United States and other parts of the world in the early 20th century as a biological control agent for aphids and other pests. While they are highly effective at controlling these pests in the gardens and crops, their rapid spread and tendency to congregate in large numbers have caused problems for homeowners.

                          These beetles are easily recognizable by their orange to reddish-brown coloration, small black spots on their wing covers, and distinctive M-shaped marking behind their head. Their size ranges from 5-8mm in length. They have six short legs and two antennae.

                          During the fall, the Asian lady beetle seeks protected locations to spend the winter. They gather in large groups, often on the sunny side of buildings, before ultimately finding their way into homes and other structures through cracks and gaps. It is not uncommon to find them gathered in attics, wall voids, or other quiet, undisturbed areas.

                          Once inside, these beetles can become a nuisance due to their sheer numbers and tendency to release a yellowish, foul-smelling liquid when disturbed. This liquid can stain walls, fabrics, and other surfaces, and may cause allergic reactions in some individuals. Additionally, some people find the beetles’ scent unpleasant or even nauseating.

                          Prevention is key to avoiding an Asian lady beetle infestation. Sealing entry points, such as cracks around windows, doors and utility openings, can significantly reduce the likelihood of an invasion. Additionally, keeping exterior lights off at night and planting trees or shrubs away from the house can reduce the attractiveness of your home to these insects.

                          If beetles have already found their way inside, using a vacuum cleaner is the best means of removal. However, be sure to dispose of the vacuum bag or empty the canister outdoors immediately to prevent the beetles from returning back into your home. Alternatively, insect light traps or sticky traps can help capture and remove beetles.

                          It’s essential to remember that while the Asian lady beetle can be a nuisance, it is not a significant threat to your home or your health. Taking proactive measures to prevent their entry and managing their presence can significantly reduce the annoyance caused by these uninvited guests.

                          As the fall season arrives, keep in mind the potential for Asian lady beetles to seek shelter in your home. By understanding their behavior and implementing preventive measures, you can enjoy the beauty and warmth of autumn without the invasion of these pesky insects.

                          Do You Dig Dahlias?

                          By Dawn Pettinelli, UConn Home & Garden Education Center

                          A couple of weeks ago, I was fortunate to visit the spectacular dahlia gardens on Enders Island in Mystic. For those unfamiliar with this retreat, an 11-acre seaside estate was donated to the Society Edmund by Mrs. Alys E. Enders in 1954. This Roman Catholic religious community offers ministry, retreats and respite to many. The grounds are open to all for contemplation or just unbound appreciation of nature and horticultural beauty.

                          Gardeners will delight in the gorgeous, well laid out garden rooms but especially be entranced by the vast array of dahlias. The gardens at Enders Island are filled with over 300 varieties of prize-winning dahlias in all colors (except blue), shapes and sizes imaginable. A Dahlia Preservation Trust was established to preserve the dahlia collection that is rated as one of the largest in New England.

                          Any of us growing dahlias while appreciating their cheery, attractive blossoms lasting long into the fall, do realize they are not winter hardy, even with milder winters attributed to climate change.  Dahlias are native to Central America. In fact, they are Mexico’s national flower. Those wishing to save the tuberous roots for replanting next year, must dig them up and store them over the winter.

                          Ideally, gardeners should wait until a frost blackens the foliage. Then, if possible, wait a week so any carbohydrates left in the above ground tissue can make their way to the roots to enable good sprouting next spring when the tuberous roots are replanted. This has been a particularly confusing fall to both plants and gardeners. Frosts have hit some areas but often not severe enough to affect all plants and dahlias in more protected sites are still blooming their heads off, a trait most appreciated by pollinators such as bees.

                          On the other hand, it is November. Time to reign in gardening activities and begin preparations for the holidays. What’s a gardener to do?

                          Since my plants were losing bottom leaves to disease and looking a little ragged, I just decided it was time to dig them and move the tuberous roots into the cellar. Before digging any dahlias, be sure to note their names. If tags were not written out when planting, make them out now if color and flower type are important.

                          Cut back stems to 2 or 3 inches and carefully dig the tubers starting at least 8 inches away from crowns so tubers do not get sliced or speared. Use a spade or pitchfork but dig in carefully. This year the soil is so dry that it was not necessary to leave the tuberous roots in the sun for a few hours so the soil clinging to them could dry and be shaken off. Every one I dug up was dry enough so that practically no soil clung to the roots. Each was placed in a separate container with repurposed labels.

                          Perusing through online sources, many suggest washing tubers off with a hose and letting them dry before storing. I have let them dry out in wet falls and shaken dried soil from them before storing but have never hosed them off. Maybe follow the approach that makes most sense to you. If any remaining soil is washed off, the tuberous roots should most likely be stored in lightly moistened peat moss or other slightly damp organic material, so they will not desiccate over the winter. For me, leaving a bit of soil around the roots that are stored in pots in the cellar over winter helps to keep tubers from shriveling with only a sparse sprinkle of water once or twice a month.

                          When happy, dahlias will multiply but it is probably best to leave the whole clump together and separate it before planting next spring when multiple buds or eyes can be seen. Keep the tuberous roots at 45 to 55 degrees F and check every 2 to 3 weeks for signs of decay or desiccation.

                          For an early start, the tuberous roots can be set into beds usually by late April unless unseasonably cold weather is predicted.
