A group of different kinds of Sansevieria in front of a window. — A small portion of the author’s Sansevieria collection enjoying some sun (photo by M. Lisy).

The Sansevieria group make up some of my favorite houseplants. Scientists recently placed them in the genus Dracaena, but its former scientific name seems to be also one of its common names. This plant has many common names including “snake plant” and my personal favorite “mother-in-law’s tongue”. Like many varieties of houseplant, there are some staples that have been around for decades, some newer species that have come to market, and some really interesting cultivars.

These plants have a rhizome, and the leaves grow from the base of your pot. They are very prolific when they like their environment. In fact, they tend to break the pots they are in, so I would recommend using plastic pots, which their growth will eventually deform. If you want to use a clay or ceramic pot, I suggest putting them in a slightly smaller plastic pot, then putting that in the clay pot. You can hide the gap between the two pots with Spanish moss. Being native to Africa, they cannot tolerate cold temperatures. Typical household temperatures work well, but avoid anything below 55 degrees F.
Their upright growth habit allows the grower to have many varieties in a small area.

Overwatering is the quickest way to kill any houseplant, but especially so with these. In the winter, you probably only want to water once a month, and sparingly at that. Do not let them get soggy or this otherwise hardy plant will rot. In the warmer months when the plant is actively growing, allow the soil to dry between waterings, but then water more liberally. These plants have the reputation of being a low light plant, which they certainly can handle. Sometimes people place them in the darkest corner where they hang on for a few months, but then eventually run out of stored resources and die. Remember they do need some light to photosynthesize so bright indirect light is best. The other problem I have seen is their unique, flat leaves can become covered in dust. Either dust them manually, use a blower, or take them outside in warm weather and hose them off.

Sansevieria trifasciata ‘Hi Color’ is a highly variable hybrid variety with a lot of yellow (photo by M. Lisy).

The Sansevieria group can be divided into two types, those with flat leaves and those with cylindrical leaves. Of those groups, there are species that grow tall and some that grow short.

The tall ones make great floor plants while the shorter ones do well when placed on a table. All varieties are fairly easy to propagate. My favorite way is to let the plant grow, and then divide them during repotting; this looks the best in my opinion. If you want more plants quicker, you can take leaf cuttings. Either dip in rooting hormone and replant, or you can place the cuttings in water to take root (change the water daily for best results).

Most of us are familiar with the green and dark green snake plant, as well as the gold edged version. There are some absolutely stunning new varieties on the market today that have selected for any of those colors. For example, there is one called “Moonshine,’ which has no pattern in the leaf at all, instead being pale green. Another interesting one is called ‘Hi Color,’ which has more yellow than green in the leaves. There are others that are selected for their rather dark green hue that approaches black in color. One of my new favorites is a different species called Sansevieria masoniana, commonly referred to as “whale tail”, “shark fin”, or some combination thereof. No matter which one you choose, you really cannot go wrong with these plants. They are readily available at most garden and home centers, so why not pick one up and brighten up your home?

Spring Gardening & Houseplants on CRIS Radio

Posted on March 22, 2024March 25, 2024 by Zidack, Heather

00:00:00 Stephen Thal

Hi, welcome to another segment on Focal point. This is Stephen Thal and I'm going to be your host for today's program.

00:00:09 Stephen Thal

But before we get into it, I just want to remind if any of our listeners have any suggestions for future programming. Please call CRIS Radio at 860-527-8000 and leave your suggestions here and they'll pass them on to me and we'll try to get them for future programs.

00:00:28 Stephen Thal

So today we're going to be getting some great information on horticulture plants that have done a lot for people and here to help us out is Heather Zidack and she's the horticulture consultant for the UConn Program at the University of Connecticut and it's the Department of Plant Science and Landscape Architecture. So welcome, Heather.

00:01:03 Heather Zidack

Thank you so much for having me today.

00:01:06 Stephen Thal

Yeah. Today I'm going to learn as much as most of our listeners cause this is a program I used to use many years ago when I had a garden, but it's been so long, I'm sure there's been a lot of new changes going on right now.

00:01:20 Heather Zidack

Yeah, there's been a lot of new trends in gardening and the Home and Garden Education Center here at UConn has done a lot to help Connecticut gardeners with all sorts of problems that they've had, you know, plant identification, bug identification and also just we get pictures of plants all the time that say what's going on to help people kind of troubleshoot their issues as well as a lot of the things that we put out to help gardeners.

00:01:45 Heather Zidack

So. Everybody in our office loves gardening and we're here to help.

00:01:50 Stephen Thal

Yeah, that's great. It sounds like we're going through one of the health programs to viral.

00:01:55 Heather Zidack

Yeah. Yeah. We really enjoy what we do here and there's a few of us in the office. We work with the UConn Soil Lab, the UConn Plant Diagnostic lab and the extension program with Master Gardeners. So we have all the - all the resources to help people figure out what they want for plants if they're trying to figure out finding the right plant for them and also what to do once they have them. So I think it will be a good thing to talk about today what we like about gardening.

00:02:24 Stephen Thal

Ok. Because I think that you're making plants sound like people with the individual personalities.

00:02:31 Heather Zidack

Sometimes they are a lot of times people you know, they say gardening has so many benefits. They say plants are the new pets, right? That's one of the things that I've been hearing. And with that it's something that a lot of people have found to be very beneficial though.

00:02:46 Heather Zidack

Through there's actually programs of horticultural therapy out there. They found that it improved physical and mental health. It can reduce stress, improve your mood, it can even help with blood pressure and muscle tension. Not to mention it's great exercise to be outside with your plants.

00:03:02 Stephen Thal

And I'm sure the same is similar somewhat with plants inside the home.

00:03:07 Heather Zidack

Absolutely. People that have plants inside their home. Found benefits of, you know, cleaning air quality and things like that, but also it's great to just have your plants there, a lot of people, myself included talk to their plants every Sunday when they water or whatever it is and it's just nice to have a little bit of green especially in these cold winter months.

00:03:29 Stephen Thal

Oh yeah, and I'm sure by doing that you end up benefiting in the long run.

00:03:34 Heather Zidack

Absolutely, it's a great thing to have. You know, if sometimes it is kind of like having someone to talk to. As silly as that is, we have a plant here in the office. Named Harry and it's a Fern. And we take care of it all the time. And we're always seeing how he's doing and if he's gotten any bigger, it is kind of like having a pet.

00:03:54 Stephen Thal

Well, let's learn a little bit about the home and garden program, the Education Center.

00:03:58 Heather Zidack

Yeah. So at the at the home and Garden Education Center, one of the big things that we do is not only answer questions with horticultural advice, but we also do kind of put out fact sheets. We have a blog, we have social media where people can learn tips and tricks throughout the week about gardening.

00:04:18 Heather Zidack

And with all of the questions that we've had come in, I thought it would be a great chance for me to share with you some of the common questions we're getting right now, especially about house plants.

00:04:29 Stephen Thal

OK.

00:04:37 Heather Zidack

So one of the first questions that that comes along at this time of year is common signs of stress and what to do?

00:04:38 Heather Zidack

So sometimes at this point in the year, your plants not looking so well maybe and I've done this before, you've forgotten to water it for a couple of weeks over the winter or even over the summer. And the initial response is to love it and give it more water and give it attention. And when we start to baby them sometimes we can actually over water. And then it doesn't look like it's getting better because what often happens is plants can only communicate in one way, and that way is through wilting. So when it wilts, it could be that it needs more water, or it could be that it's getting too much water. So the best way to learn which one it is is to know the species of your plant. And you also need to take a look at the soil itself and feel it if it feels like it's too wet. If it feels like something, you wouldn't want to stick your hand in. It's probably too wet for the plant, and so that's some ways that you can kind of work through that issue. And try to make sure that you're not over watering, especially when something's dried out for too long.

00:05:43 Stephen Thal

So in terms of the soil lab, when do you send the soil up to you people to evaluate?

00:05:50 Heather Zidack

So our soil lab, they take samples for a lot of outdoor things instead of the house plants. But the best time to do it is either in the spring or in fall. If you do it in the fall. Sometimes there can be a little bit quicker of a turn around time because it's not on as many people's minds.

00:06:06 Heather Zidack

So that's the pro tip right there. If you send it in now, you do get a response and they give you all sorts of information about nutrition as well as how much you might need to put onto the soil to help it get back to that optimal level. So it's a good way to find out what you need and what you have.

00:06:25 Stephen Thal

We'll be giving the address and everything towards the end of the program as to where they can send it.

00:06:30 Heather Zidack

Yes, I can do that absolutely.

00:06:32 Stephen Thal

How do you do plant diagnostics?

00:06:35 Heather Zidack

So plant diagnostics is a is a fascinating thing that not everybody knows that we have here the way that it really works out well is people send in their plant samples. And sometimes something will look sick or it will be caused by something other than the environment. And it's hard for us to see that with our eyes. And sometimes we need to send in that sample to see what it is going on inside the plant. So our plant diagnostic lab does all sorts of microscope work. They do a lot of chemical tests and strip tests for different diseases of the plants, and they also they know what to look for with symptoms and location and are able to advise. Kind of. The next steps to take if you do have something that's diseased, we help out both commercially and homeowners themselves to learn what's going on with the tree, what's going on with the shrub, what's going on with crops that are being grown, and how to how to manage them. So it's a really cool thing that we have here as well and I can give you their contact information too.

00:07:42 Stephen Thal

How about the UConn extension Master Gardeners program?

00:07:47 Heather Zidack

Yeah. The UConn Master Gardener program is also a really good resource. One of the benefits that they have is that there is an extension office in every county of Connecticut and you're able to connect with a master gardener. They are a group of individuals who every year there's a new class. They go through a training program and learn how to become a master gardener. And they learn a lot of the things that we talk about here in home and garden as well, where it's soil conditions and plant selection and how plants grow. They learn all of those different things.

00:08:26 Heather Zidack

And they actually work with the public to help them understand them as well as part of a community outreach project that they each have to do. So it's a great program for people in Connecticut to either, if they love gardening, to pursue it further and get that master gardening title for themselves. Or to go to as a resource. And like I said, it's great that there's one in every county in the state.

00:08:52 Stephen Thal

Well, that's good. So how do you find their number?

00:08:56 Heather Zidack

So they actually go through UConn Extension Master gardener. You can find their website and you can find it through that or I can give you their number as well.

00:09:08 Stephen Thal

Ok. Why don't we take a break and let's give out some of the phone numbers for these programs we just talked about?

00:09:15 Heather Zidack

Fantastic.

00:09:16 Stephen Thal

OK, so the first program would be soil samples.

00:09:21 Heather Zidack

Yes. So our soil lab can be reached at 860-486-4274, 860-486-4274. That's for the soil nutrient analysis laboratory.

00:09:40 Stephen Thal

Right. And how about the plant diagnostics lab?

00:09:44 Heather Zidack

So the plant diagnostics lab works with our office as well, and you can call for plant diagnostics or for the Home and Garden Education Center at 860-486-6271, 860-486-6271.

00:10:05 Stephen Thal

And how about the UConn extension and master gardener?

00:10:09 Heather Zidack

The Master Gardener program can be reached at 860-486-7178. Again, that's 860-486-7178.

00:10:23 Stephen Thal

So there you have some phone numbers to call and educate yourself. How to help make your plants stay healthy and to really give you some benefits. I know my wife has found some plants in in the garbage and she's taken them and replenished them. And then now growing great.

00:10:44 Heather Zidack

Yeah, a lot of people are able to revive plants after they've they've taken a little bit of a hit. It's amazing how forgiving plants can be. Sometimes we see them and they haven't been watered for too long or they're they've been in the wrong condition and it's just a matter of taking care of something. And again, that leads into one of the benefits where there's a sense of pride of I brought this back. Or I've really accomplished something with what I've done, sorry.

00:11:12 Stephen Thal

Now with plants, I'm just curious, do you have to have good vision to have a plant so you know it's getting in bad shape?

00:11:20 Heather Zidack

Not necessarily. There are a lot of things that you can learn through feel when you're working with plants. Sometimes if you feel the leaves especially. If you're feeling if you have succulents, for example, there are very popular house plant that people will have on windowsills and in their offices and things like that. And with succulents you can actually tell if they need water by the feel of the leaf. If you pinch a succulent leaf and feel the leaf between your fingers. It's actually, it should feel firm and a little bit smooth to the touch.

00:11:58 Heather Zidack

If it needs water. They get a little bit squishy and a little bit rubbery, and so that's how, you know, maybe it needs some water. At this point. The other thing that you can do is you can feel the soil to tell if something needs water or not. The other thing that you can do to assess health of a plant is feel the leaves of themselves and if there's ever a crunch, you know that's a bad sign and that there's something going on. Either disease or possibly just watering. And you also can tell the differences you're feeling. If there's been any issues with like chewing marks you can feel a lot of times. Insects will leave a sticky residue so you can tell what's there. So there's a lot of senses other than vision that are involved when it comes to looking at your plants and their health.

00:12:45 Stephen Thal

Yeah, that's good to know. Because uh, some of our people may not be able to see the plants, but they really enjoy having them around in the house.

00:12:56 Heather Zidack

Absolutely. It's one of those things that the plants are multi sensory and so we're able to kind of understand them through more than just vision.

00:13:06 Stephen Thal

And you mentioned the word succulent. What are some examples of succulent plants?

00:13:12 Heather Zidack

So a succulent plant is kind of an overarching group. They are all of the ones that love to be in dry conditions a lot of times they are. They are not cactuses but they end up being lumped into that group where they like those drier conditions. They tend to be the ones that look like little rosettes. Or little mounds on the soil that will grow from there. They're very I. I talked about the rubbery texture. They some of them almost don't seem real when you feel or see them because they have this this very strange look to them. So they're a very popular plant because they're so easy to take care of and they're also very unique in their appearance.

00:13:57 Stephen Thal

This is Stephen Thal and another focal point program and we're interviewing Heather Zidack and she's from the UConn Extension program and we're learning about what that program is all about. There are several programs and we've shared some phone numbers earlier and she's educating us on more and more and how we. And be with the plants, enjoy them and have fun with them. What are some of the other benefits of the plants?

00:14:30 Heather Zidack

So another great thing with having your plants is like I said, that sense of pride and accomplishment and what you've done or what you've been growing and producing. So it's something that it gets you outside. If you have an outdoor garden or even if you're inside it has you proud of what you've accomplished, some people grow vegetable gardens. And they are so proud of all the produce that they grow and what they're able to do with that. So there is a sense of pride and joy that comes with gardening. There is exercise benefits, there's all sorts of great things that come with working with plants and being part of that. You're connecting with nature. So it's always a great thing to be able to connect back to nature.

00:15:14 Stephen Thal

And also they have found that it helps people reduce stress.

00:15:19 Heather Zidack

Yes it can. It can reduce stress. It can reduce blood pressure. It can help with your pulse and help bringing your heart rate down and muscle tension. It's a great way to take a break from everything else you know, being even from personal experience, when I'm able to go out into my own garden or transplant my house plants or plant my seedlings, it's a break from everything else that's going on. We get very busy with our lives and being able to take that break and go garden.

00:15:53 Heather Zidack

Or go, you know, take 5 minutes to just take a breath and trim some plants. It's a great way to de-stress.

00:16:02 Stephen Thal

In terms of fertilizers, how do you know which one to use for different plants?

00:16:10 Heather Zidack

Usually picking a fertilizer can be a little tricky. You have to know what species of plant that you're working with, and then you're able to figure out from there. And that's something that we would be able to help with for sure.

00:16:23 Heather Zidack

In general terms, plants need three big things to be able to grow. They need nitrogen, phosphorus and potassium. And so when you're looking at fertilizers, a lot of times you'll see that there are three numbers there and they're always like in increments of five or ten, like it says 5-5-5, 10-10-10, 20-10-20 those are all ratios and a balance of those three main nutrients. Your first number is nitrogen and then phosphorus and then potassium. And in general terms of balanced fertilizer is always the best way to go.

00:17:01 Heather Zidack

Those different elements can encourage flowering versus root growth versus leaf growth. But when you're trying to take care of the plants that you have, that balanced fertilizer makes sure that you're getting enough fertilizer and enough nutrients to the plant in a balanced way.

00:17:21 Heather Zidack

Our clients that go through our soil lab, they get specific recommendations based on what they have for soil and what they're looking to grow.

00:17:31 Stephen Thal

Let's take a look at some of the common questions you get from your constituents. So what are some of the common signs of stress and what to do?

00:17:41 Heather Zidack

Yeah. So with stress, with plants, it's one of those things where like I said they have-They only have one way to communicate, and that's through wilting. They can change color as well, but wilting is really that big flag of communication and so they can wilt if they're overwatered, they can wilt If they're underwatered. They will also change colors at times and so that makes it difficult for us sometimes to know what's going on.

00:18:09 Heather Zidack

When you're looking at stress, if you have a plant that is wilting, or if you have a plant that is feeling spongy like I had mentioned before, it doesn't feel like it's firm. And the way that it should be, the first thing you want to look at is watering, so make sure that you have enough water in the soil. It's not too dry, it's not too wet. That's a good thing to start with. Additionally, you can start looking at the conditions around it. So one of the things is sometimes you.

00:18:40 Heather Zidack

Look at it and you think would I be happy sitting in this spot? So is it getting enough light? Is it getting a draft from the window near it because it's getting a little bit colder than it should be. A lot of house plants that we have come from tropical regions and so they want to be warm. They want to be they want to have a little bit of humidity and they want to have the right amount of water so. Taking a look at them and saying is this the spot for this plant is a way to kind of look at the stress and manage it.

00:19:13 Stephen Thal

What are some of the other questions that people are asking in terms of the plant itself?

00:19:19 Heather Zidack

Another question that we get a lot of the time is the question of “is it dead?” We get pictures of plants and people are worried that they have killed their house, plant or even sometimes plants outside. And one of the things with plants that you need to be aware of is that some of them can go through a process called dormancy. It's a lot like hibernating in the winter, and when they go through dormancy. You notice this with trees outside. They drop their leaves, they get kind of gray looking. They don't look like there's a lot of life in them. And so in that dormant state, one of the ways that we can see if they still have life in them is to go ahead and scratch the surface of the stem.

00:20:07 Heather Zidack

And if you are able to see it, you'll see that there's some green or whitish tissue in there, and that that means that there's life in the stem. Still, if you struggle to see it, you should feel a difference and that it will catch on your fingernail instead of just being a dry break. And so if you feel that where it's catching. Then it's actually there is some life there and it means that it's going to come back from dormancy now, that's where things with woody stems. If there's plants that are dying back all the way to the ground, it's really hard to tell. Is it dormant or is it not? And a lot of times, we recommend just giving it time.

00:20:46 Heather Zidack

Sometimes plants nap a little bit longer than others, and so it's really important to give them their time to make sure that they've come out of dormancy. This goes for both house plants as well as plants in the ground. There are some perennials here in Connecticut that don't even start waking up until after Memorial Day in May and so give it time. Have a little patience. There might be some life there. It's just a matter of waiting for it to come back.

00:21:14 Stephen Thal

I think another question is do you have recommendations of house plants?

00:21:18 Heather Zidack

Yeah, another. That's another question that we get a lot and it's different recommendations of what to grow for varieties. And so I actually have a list here for you of house plants that have varieties and texture, scent, color and movement because who wants to have just green plants around, right? We have so much selection now in the plant world that it's really awesome that we can bring some interest into our plants. One of the first ones that I always love to recommend is it's called a prayer plant or a calathea. What they do is they will either curl their leaves or bend them up and down depending on what time of day it is. So.

00:22:02 Heather Zidack

It adds a little movement. They tend to have a lot of bright colors to them. My personal favorite is called rattlesnake calathea. And it has some really big spots on it. Purple underside to the leaf, and it'll actually fold its leaves straight up in the air at night, and then during the day those leaves will come down to get the sunlight. So it's really cool to add some movement. Another thing that people like to do is they have some scent in their house plants, so adding scented geraniums, those are a type of geranium.

00:22:39 Heather Zidack

It's related to the ones that we see all year in the summer. However, it's different in its flower and also in its scent. When you touch it and move the leaves you get a really nice scent out of them. Some are peppermint, they have apple, they have lemon, they have all sorts of different geranium scents, so if you start looking for scented geraniums, that's a really cool way to add some fragrance into your house plant garden. Another really good plant to have is the sensitive plant. It's as its name says, it's a little sensitive and that whenever you touch it, it will recoil and those leaves will drop right down. And it takes maybe 10-15 minutes for them to recover and open, back up and then they will do it again.

00:23:28 Heather Zidack

The sensitive plant is a really cool thing that I used when I was working in the garden center. We would use it in fairy gardens and children absolutely loved to be able to touch it and have it actually move. It brought more life to that little garden that they created. Another one is called the Chenille plant.

00:23:48 Heather Zidack

Where it has fuzzy fuzzy flowers, they feel like little rabbit feet and they are bright red so you can grow it as a hanging basket. You can grow it in a little pot as a house plant where you can put it outside during the summer. So it's a really versatile plant that adds some texture and brightness and like I said, they're very fuzzy. It's one of the wildest ones that I've seen. There's another called a Tricolor Stromanthe that is green, cream, and pink and the leaves have different colors all year long. So it's another nice way to get away from just green house plants. And then lastly, the other one that is a good conversation starter at the very least.

00:24:29 Heather Zidack

Is the carnivorous plants or the cacti that can add interest and they can add texture and it's just like I said, a conversation piece of “Wow, what is that?” And it's a Venus Flytrap that will close up when touched by flies. Or there are some pitcher plants out there that also attract insects that are carnivorous as well. So it's just a cool way to add something to your collection that's not just green and it adds texture and scents and really involves all the.

00:25:00 Stephen Thal

And we have a few minutes left in our program and I was wondering if you could make suggestions on where people can buy plants and how they can tell they're making sure they're getting a good plant without disease, without flies or whatever else.

00:25:14 Heather Zidack

Yeah.

00:25:17 Heather Zidack

Yeah. So we always recommend shopping local when possible. And so there are independent garden centers in the state that offer a wide selection of plants. However, there's also a lot of hardware stores and box stores that you can get good material at as well.

00:25:35 Heather Zidack

When you're looking for your plants, it's the plant itself that you want to make sure it's healthy, more so than where you're shopping. So taking a look, feeling that soil, like I said, if it's bone dry, chances are it hasn't been watered in a minute. And maybe that could affect the plant itself.

00:25:55 Heather Zidack

Use some of those senses that I've talked about previously where you're feeling the leaves and feeling for some crunch. Or really if they're succulents, getting a feel of that leaf to make sure that you're aware of what it feels like. Some people will bring home plants to rescue. But if you want a nice lush plant, start with that. Don't look at something and feel like oh man, this is a little bit rough and I could save it if you want to start strong, start with a plant that is healthy. There's no spots, there's no tears.

00:26:27 Heather Zidack

If you feel any chew marks, if you're able to see the roots, sometimes you see roots growing out of the pot. Check that they're not black and mushy. Make sure that they're white and firm.

00:26:41 Heather Zidack

And really, most plants from from garden centers are going to be in pretty good shape and they'll thrive with care. So really it's about the plant and make sure it's healthy when you start and then just do your best to take care of it once you get it home.

00:26:56 Stephen Thal

And I noticed that there are a couple of areas that we didn't mention quickly, like herbs are good to do.

00:27:02 Heather Zidack

Yes, yeah, herbs are great.

00:27:06 Heather Zidack

If you're doing, especially if you're doing a container garden or raised bed gardens, herbs are really great to mix with your flowers. The nice thing is that herbs will add a little bit of scent and use. You can actually harvest them and use them in your cooking in addition to the container plants that you have. So we recommend that with a lot of outdoor containers, more so than indoor. However, if you're growing herbs indoor, just grow them separately from your other house plants.

00:27:37 Stephen Thal

And also the sunlight is important too, because some plants don't like sunlight all the time. Some do.

00:27:44 Heather Zidack

Right. Yes. So sunlight is one that can be tricky too, and I explained that if you think about if you've had a cat and you understand how cats behave, plants can kind of feel the same way. So anything that requires direct sun or full sun.

00:28:00 Heather Zidack

If you think about a cat laying in the sun on a on a nice warm day and it's right in the window where it can get that sun. That's what direct sun is. It has to be in contact with the leaves for six hours a day or more. If anything asks for indirect sun, that means that the sunlight doesn't directly contact the leaves but it likes to be able to be somewhere that it can see that light for six hours or so a day. That's kind of like your cat that sits near the window and watches, but maybe that spot in the direct sun is a little too warm for him. So he shifts over a little bit.

00:28:37 Heather Zidack

And then you have shade and with shade. The sun does not make contact with the leaves at all. That's kind of your cat that's going to hang out on the couch and doesn't care too much about being near the window at all. So that's a really good way to remember direct sun, indirect sun and shade is kind of where does that cat like to hang out?

00:28:56 Heather Zidack

It's kind of funny, but it works.

00:28:58 Stephen Thal

Do you have any final recommendations for our listeners?

00:29:02 Heather Zidack

My biggest recommendation is to just get out there and garden. You know, we talked today about some of the best benefits of gardening and working with plants. And don't be afraid. It's one of those things that's really great to do. And don't say I don't have a green thumb. You can do it. You just need to maybe get a little bit of advice and we can offer that here at the garden Home and Garden Education Center, but maybe you just need to do it and say I did it, so get out there and garden.

00:29:35 Stephen Thal

Heather, why don't you leave your phone number in case people want to talk to you directly.

00:29:41 Heather Zidack

Yeah. So I can be reached at the Home and Garden Education Center and my number here is 860-486-6271, 860-486-6271.

00:29:57 Stephen Thal

It has been very interesting. We've given out a lot of information and we hope that our listeners will take you up on it, call you and if they need more information. Ohh. One other thing I forgot to ask, is there a cost involved for the soil samples and all this sort of thing?

00:30:14 Heather Zidack

So for soil samples there is a cost.

00:30:17 Heather Zidack

For our plant diagnostic lab, if a sample needs to be submitted, there is a cost. However, working with the UConn and home and Garden Education Center, our advice is free and we will also if you if clients e-mail us pictures, we can kind of take a look and get the ball rolling and sometimes we can we can make a determination from a picture, so advice that comes out of the office that I'm in is free.

00:30:41 Stephen Thal

We appreciate your coming on and we'd love to get you back in the fall. So give us a call, call me like in August.

00:30:49 Heather Zidack

Yeah. Thank you for having me.

00:30:50 Stephen Thal

And let's see if we can get you back in, whether you come in September or October, you let me know and we'll work it out with the studio in terms of, yeah, having you get involved.

00:31:00 Heather Zidack

That would be great. Thank you for having me.

00:31:02 Stephen Thal

Yeah, it's a pleasure. You know, we try to cover a wide range of things for our listeners and we know that some of our programs really move the people forward and get some things done that they like.

00:31:14 Heather Zidack

That's fantastic. Yeah.

00:31:16 Stephen Thal

So we want to thank you. This is Stephen Thall with another segment on focal point. We want to thank everyone for allowing us into your homes. Couple of last minute comments first.

00:31:25 Stephen Thal

Please wear your sunglasses and a hat during these days when you're outside with the sun because it's protects your eyes and the second thing is develop an emergency plan at home and practice it. And when you're traveling, make sure that you go to places where there's at least two exits. So in case one is blocked, you can get out the other door.

00:31:48 Stephen Thal

So again, thank you all for listening. Stay safe, stay healthy.

A Beginner’s Guide to Orchids

Posted on March 21, 2024March 25, 2024 by Zidack, Heather

By Dawn Pettinelli, UConn Home & Garden Education Center

Orchids, with their captivating beauty and elegance, have long held a revered status among plant enthusiasts. If you’re tempted to dive into orchids, this is the perfect time to explore what’s available as it is orchid show season. Those looking for a day trip might want to explore Florals in Fashion at the New York Botanic Garden until April 21. Closer to home, the CT Orchid Society holds its show April 20-21 at the Bristol Senior Center.

Often associated with exotic locales and intricate care routines, these plants are surprisingly adaptable and many can thrive in the comfort of your own home. Whether you're a seasoned gardener or a novice looking to add a touch of sophistication to your indoor space, cultivating orchids can be a rewarding endeavor.

Orchids belong to one of the largest and most diverse plant families, Orchidaceae, comprised of over 25,000 species. They come in various shapes, sizes, and colors, but broadly speaking, orchids can be categorized into two main groups based on their growing habits: epiphytic and terrestrial. Epiphytic orchids grow on trees and absorb their moisture and nutrients mostly from rain. They are usually found in tropical rainforests and need a specialized bark based growing medium. Terrestrial orchids grow in soil and while the most spectacularly colored ones come from the tropics, we are fortunate to have native terrestrial orchids such as lady slippers.

Another important distinction among orchids is their growth pattern, which can be classified as sympodial or monopodial. Sympodial orchids grow horizontally sending out new shoots or pseudobulbs from a rhizome or creeping stems. Cymbidiums and dendrobiums are species that exhibit this behavior. Monopodial orchids grow vertically, with a single stem that continues to elongate as the plant matures. Paphiopedilum and vanda species have this growth habit. Understanding these distinctions can help you tailor your plant care routine to suit the needs of your orchids.

The key to growing orchids successfully in the home is understanding the conditions they need to grow and thrive. These will vary according to the species but in general orchids need bright, indirect light. East and south windows usually supply ample light, but a sheer curtain may be needed to keep orchids out of hot sun from south windows during the summer. Direct sunlight may burn their leaves. Orchids also do well under artificial light.

Next to light, temperature is critical as some like it hot and others thrive in a cooler environment. It makes the most sense to select the orchid species that would do well in the temperature range you prefer. Most species, however, are happiest if there is a 5 to 10 degrees drop in night temperatures.

Orchids also tend to do best in more humid environments and our homes are mostly on the dry side. Consider using a humidifier, using pebble filled trays under plants or even growing plants in ornamental glass cases.

Making sure your orchids are receiving the proper amount of watering can be challenging to beginners. Terrestrial orchids are usually grown in an orchid bark & enriched potting soil mix and need to be kept moist but not overly wet. Epiphytic orchids in orchid pots with bark or attached to slabs of tree ferns can be drenched or dunked and then drained. The roots should not sit in water very long. Some experimentation will be needed to determine frequency of waterings.

There are so many species of orchids to choose from but beginning orchid enthusiasts might start off with dendrobium species. Dendrobiums are one of the largest and most diverse orchid genera made up of numerous species as well as hybrids. They are even sold at my local grocery store. Dendrobiums are known for their brightly colored flowers that usually bloom in clusters along long stems. They are relatively easy to care for and tolerate typical household conditions.

Phalaenopsis orchids are another large genus that are tolerant of a range of household conditions so are ideal for beginners. Plants can tolerate a little less light than many other species so east windows work well. Nighttime drops in temperature are important to initiate new flower stalks.

Those with cooler growing spaces might want to try Cymbidiums. These plants are just gorgeous in bloom with their long-lasting sprays of colorful flowers. Cool temperatures and bright light are keys to healthy, floriferous plants.

Lady slipper orchids (Paphiopedilum) have distinctive pouch-shaped blooms, similar to our native lady slippers. They are terrestrial orchids preferring a very well-draining potting mix and indirect light.

If orchids are just too alluring, try to attend an orchid show or two, visit local garden centers that sell orchids and can answer your questions about them, or even check out the resources at the American Orchid Society (https://www.aos.org/) to find out information about caring for these beautiful, mysterious and addictive plants. For basic orchid information or if you have any other gardening questions, contact the UConn Home & Garden Education at (877) 486-6271 or www.homegarden.cahnr,uconn.edu or your local Cooperative Extension Center.

The Do’s and Don’ts of Early Spring Gardening

Posted on March 14, 2024March 15, 2024 by Zidack, Heather

By Heather Zidack, UConn Home & Garden Education Center

There’s a well-known scene in the movie “Braveheart” where Mel Gibson’s character, commands his men to “Hold!” as the enemy is rushing upon them. It’s a scene that I often reference as an analogy for this part of the year. Daylight savings time has changed our clocks, the sunshine is warm, temperatures are reaching the “light jacket” level of comfortable, and we all feel spring rushing towards us with the promise of seedlings, flower buds, and fresh green leaves. With this, there are certainly plenty of chores that we can do right now to prepare, but there are others that we really should be waiting for a few weeks longer.

Houseplants may enjoy a short afternoon in the outdoor sunlight on these warmer days but resist the urge to put them outside full time until night temperatures consistently reach 50 degrees Fahrenheit. The occasional day trip is an effective way to help them transition from the protection of your indoor environment to full sun outdoors. More importantly, consider giving your houseplants a good spring cleaning. Repot or divide root bound plants, remove the winter dust from leaves with a damp rag, and trim out any dead or unsightly growth. Now they’re ready for their spring debut!

Fertilizing is another task that many gardeners feel may be a chore to check off their lists early. This is a project that should wait a little bit longer. Often, fertilizer will push new growth in your plants. Pushing them too early can leave tender leaves and buds at risk of exposure to frost and freezing temperatures, actively slowing or stunting growth that you intended to give a boost to. In the same vein, grub control, pre-emergent, and many other synthetic materials used in the landscape require specific soil temperatures to be effective and it’s still just too cold. Always read the label of any garden product to learn the best timing of any application. At this point in the year, consider doing a soil test. If you haven’t done so before, it's great to have a baseline for planting and caring for your garden. If you’ve done it a few years ago – check it again! Things change and you may be surprised by what nutrients you need (or don’t) since you last checked in.

It may still be a little early for mulch as well. Adding fresh mulch too early in the season can trap moisture and slow the soil from warming up to optimum growing temperature. Take this time to pull out grass and weeds that may have taken root in mulched beds and put this time into your hardscape. Look for tripping hazards to address like cracked, sinking, or heaved pavers. Check structures like pergolas, sheds, and even raised beds for rotting boards, warping, or structural damage. Repair as needed. Building new garden spaces is always an option! Create your punch list of projects that will need fresh paint or sealant. If the weather is going to be warm and sunny – consider power washing hardscapes and structures now.

Late winter/early spring is a fantastic time for pruning trees and shrubs in the landscape. It’s ideal because there is great visibility, and the cooler temperatures prevent disease and insects from taking advantage of fresh wounds. You want to make sure you’re pruning correctly, for the species and purpose of the trees and shrubs in your landscape – so do your homework! As a rule of thumb, roses, hydrangeas, and some hardy perennials tend to appreciate a later pruning and can vary between types within the species, so stay aware of what you have on your property to ensure success!

“But when do I get to play in the dirt?” That's next! For our outside plants, think about dividing perennials. Divisions at this point in the year make the plants much easier to handle for the gardener. Moving your plants now gives them a chance to “wake up in place” this spring. You will reduce concerns with transplant shock when you move plants ahead of their spring flush and our summer heat.

Indoors, stepping your seedlings up into larger containers gives them a little more breathing room as we wait for the season to start. Only transplant seeds when they’ve started to show 2-3 sets of true leaves and keep in mind that different species can have different needs. If you excitedly started your tomatoes too early, and now notice leggy stems, try transplanting them in plastic cups and burying them all the way up to their first couple sets of true leaves. They will put out even more roots along that covered stem and be even better prepared when you put them in the garden this season!

Tips for the February Gardener

Tips for the February Gardener

By Dawn Pettinelli, UConn Home & Garden Education Center

February is a tough time for gardeners. Days are getting longer but the cold temperatures, and in many cases, snow, are keeping us inside. This is a good month to provide houseplants with a little TLC before the weather warms and the gardens beckon.

If possible, bring your plants one by one to the kitchen sink. Give them a thorough grooming by removing any dead or off color leaves. Trim back wayward or undesirable growth. Then give them a good rinsing under the faucet or use a wet cloth to wipe dust off of their leaves. For plants with hairy leaves, like African violets, a soft brush could be used to clean their leaves. Wash their saucers out before setting plants back.

Plants that have outgrown their pots can be repotted at this time. Usually, plants would be moved up to a pot that is an inch or 2 wider. Loosen or trim roots if they are growing in a circle or very dense. An all-purpose potting mix can be used for most plants but specialized mixes for plants like cacti and African violets are also available.

Your amaryllis has probably finished blooming by now. Cut off any spent flowers. Some people like to leave the stem until it yellows as it can photosynthesize but I generally remove the whole stalk after flowering. If you want plants to rebloom next year, the foliage needs light, water and nutrients to grow. Set your plant in a bright location and fertilize monthly starting in March. Plants can be moved outdoors after the danger of frost has passed either in their pots or set them into the ground in a part shady spot. Bring inside in mid-October and let the bulbs go dormant in a dark, warm area for about 8 weeks and then repot for another season of striking trumpet-shaped blooms. Some cultivars do not require a dormant period.

Check on any tender bulbs that you have in storage. Dahlias and tuberous begonias can shrivel if they dry out too much. They are usually stored in some barely moistened peat moss or wood shavings. Sprinkle with a little water if they are on the dry side. Also, this would be a good time to check on any winter squash, potatoes or other vegetables that you’ve been keeping. Use them up before they spoil.

Time spent perusing garden catalogs, either in print or digital format, is a great way to get through cold, winter days. When making out a seed order, don’t forget to note what seeds you have leftover from last year. Most seeds retain their viability for at least a year. It’s always a good idea to plan out the vegetable garden so you know what’s going to be planted where, and when. Last frost dates for your area can be found at: https://garden.org/apps/frost-dates/. The UConn Master Gardener program is offering a Garden Journal with tips on how to plan and maintain your flower and vegetable gardens and plenty of room for you to make notes. To order go to: https://mastergardener.uconn.edu/2024/01/30/garden-journals-available/.

Most of us recognize the benefits of buying local when it comes to produce and other Connecticut grown products but did you know we have at least 5 seed companies in Connecticut. They include Select Seeds (www.selectseeds.com), the Chas. C. Hart Seed Co. (www.hartseed.com), the Heirloom Market at Comstock Ferre selling Baker’s Creek Heirloom Seeds (www.heirloommkt.com), John Scheppers Kitchen Garden Seeds (www.kitchengardenseeds.com), and New England Seed Company (www.neseeds.com). Be sure to see what they have to offer either online or at various retail locations.

If you need a floral fix to get you through to spring, stop by the CT Flower and Garden Show at the Convention Center in Hartford, Feb 22 -25. Visit the UConn Home & Garden Education Center’s booth for a free pH test (bring a half cup of soil) and answers to your gardening questions. A blooming time can also be had at Elizabeth Park’s Greenhouse Bulb and Plant Show, March 1 – 9. Since spring can’t be here soon enough, you’ll just have to go to where the flowers are blooming!

Hearts for Valentine’s Day

Posted on February 6, 2024February 6, 2024 by Zidack, Heather

Hearts for Valentine’s Day
By Dawn Pettinelli, UConn Home & Garden Education Center

While there’s always the traditional Valentine’s Day gifts of flowers and candy, why not give that special someone a plant with heart-shaped leaves that will likely last much longer than chocolates or bouquets. There are actually a number of plant species to choose from with some being quite easy to grow.

Perhaps the cutest, as well as the easiest is the Sweetheart hoya (Hoya kerrii). Hoyas are a very slow growing, vining plant with stems that may reach 13 feet in length. Typically, it is grown in a wreath form or on a trellis. The pink or white flowers are fragrant but not produced in great abundance.

While this plant has the most adorable heart-shaped leaves, the ones that are sold as a single leaf in a pot will, in most cases, remain as a single leaf. Unless a piece of stem was left attached to the potted leaf, the plant is not able to initiate new leaf or stem formation. This makes for a simple plant to care for, however. Keep your Sweetheart hoya leaf in a bright sunny spot with temperatures in the 60 to 80 degree F range and water when dry.

Another plant for small spaces with charming marbled, heart-shaped leaves is the String of Hearts (Ceropegia woodii). While the dainty individual stems can grow 12 feet long, they can be trimmed to keep the plant compact. The grey-green leaves are small, only about ½ inch in diameter. String of Hearts is a succulent best grown in a potting mix labeled for cacti and set in bright, filtered sunlight. Let plants dry out slightly between waterings. Keep away from drafts and note that plants may go dormant if the temperature falls below 60 F.

Philodendrons (P. hederaceum) have been grown for ages and with good reason. These tough, vining plants with heart-shaped leaves tolerate the lower light levels found in many homes. Stems may grow 3 feet or longer and plants are best suited to a hanging basket or trellis. Exciting newer cultivars such as ‘Brasil’, ‘Cream Splash’ and ‘Rio’ offer variegated leaves. Grow plants in bright, indirect light and avoid overwatering. Trim plants if they overgrow their bounds.

More recently, anthuriums with their flashy colored spathes in red, orange, pinks, and purples have been livening up the holiday plant scene. Both the spathes, which are modified leaves, and the true glossy, green leaves are shaped like hearts. Plants grow to about 16 inches high and if content will produce long-lasting colorful spathes several months of the year. Tiny flowers are on the tail-like spike that emerges from each spathe. Anthuriums also appreciate bright but indirect light, a well-draining, acidic soilless potting media and to be kept moderately moist.

Similar in care to anthuriums, syngoniums have heart-shaped leaves and new varieties come in various shades of pink, purplish red and even variegated cultivars. Syngoniums are evergreen climbers but can be maintained as a shrubby houseplant if trailing stems are removed. As the plant ages, leaves become more arrow-shaped. Plants enjoy warmth and humidity and do best in moderately moist potting mixes and in bright diffused light.

A little harder to find but worth the search is the Heart Fern (Hemionitis arifolia). Like many tropical ferns, it prefers indirect light in a warm, humid location. Plants may reach 10 inches tall and wide. The leaves are dimorphic, with the sterile fronds being heart-shaped and the fertile ones resembling arrowheads. Unlike most ferns, the foliage is thick and leathery. Being an epiphyte, plants should be grown in a light, airy potting mix and kept moist at all times.

Lastly, there are varieties of English ivy (Hedera helix) with heart-shaped leaves. ‘Sweetheart’ and ‘Heart’ are two common cultivars. Blue-green leaves form along stems that can be trimmed to any length. Grow as a hanging basket or in a decorative pot. English ivy enjoys cooler temperatures and bright but diffused light. East or north facing windows are ideal locations.

This year, mix it up a little for Valentine’s Day and give the heart-felt gift of a plant with heart-shaped leaves. Do note that some of the above plants are toxic if consumed so should be kept away from children and pets.

If you have questions about these plants or if you have any other gardening questions, contact the UConn Home & Garden Education at (877) 486-6271 or www.homegarden.cahnr.uconn.edu or your local Cooperative Extension Center.

Alluring African Violets Chosen as 2024 Houseplant of the Year

Posted on January 22, 2024January 22, 2024 by Zidack, Heather

Alluring African Violets Chosen as 2024 Houseplant of the Year
By Dawn Pettinelli, UConn Home & Garden Education Center

This last decade or so has seen a burgeoning interest in houseplants. While this has led to the introduction of some new and exciting species, classic stalwarts are still in demand as evidenced by the National Garden Bureau naming African violet the 2024 Houseplant of the Year. They are from Africa, as their name implies, but they are not related to the violets we commonly encounter in our gardens. These plants were discovered in the mountainous regions of Tanzania and Kenya where they grew in shady, rocky locations.

The first person to successfully send plant material back to Germany where it eventually reached the Royal Botanic Gardens at Herrenhausen was Captain Baron Walter Saint Paul in 1892. This new species of plant was placed in the Gesneriad family and given the Latin name, Saintpaulia ionantha. A number of additional species were described over the next half century. More recently, after DNA analysis, African violets were put in the genus, Streptocarpus.

Regardless of their classification, African violets are endearing plants showering their caretakers with an almost continuous parade of blossoms if properly taken care of. Maybe the most difficult part of growing African violets is deciding which ones to grow. They can be found as miniature, standard, and trailing varieties and there are thousands of cultivars. In fact, the African Violet Society of America (www.africanvioletsocietyofamerica.org) has a Master Variety List of over 16,000 recorded species and cultivars.

Flower color ranges from white to pink, purple, blue, violet as well as bicolored cultivars. They can be single, double or semi-double, ruffled or picoteed. Leaves can be a handsome green, some with burgundy overtones while others can be variegated or mosaic. Whichever type or cultivar of African violet you choose, care is similar.

The proper amount of light is key to good flowering. Plants need lots of bright indirect light. East windows are usually ideal as they get morning sun. If only a west or south facing window is available, filter the light with sheers. African violets do exceptionally well under fluorescent or LED lights. Consider artificial lighting if natural light is limited.

Temperature is also important. African violets mostly thrive in the same temperatures we do, around 65 to 70 degrees F. Place them where nighttime temperatures do not drop below 55 F. This is more likely to be a problem during cold winters when plants are left too close to windows. Often exposure to cold results in the plant starting to wilt. Daytime highs ideally should not exceed 75 F.

When watering your African violets, avoid getting water on the hairy leaves as this may cause spotting. Many African violet enthusiasts choose to water from the bottom. Plants can be grown in special ceramic African violet pots where a well is filled with water, and it keeps the root ball just moistened enough. Plants can also be watered using a watering can with a long narrow spout so water can be directed at the potting mix and not land on the leaves. The potting mix should stay moderately moist at all times but should not be saturated. If watering from the top and excess water drains into a saucer, be sure to empty it. Soggy soils promote crown and stem rots.

African violets like a very well-draining potting mix rich in organic matter with an acidic pH. One can purchase specialty mixes for African violets, or a standard soilless commercial potting mix will do. While plants do need to be fertilized during their period of active growth, which is usually spring and summer, note if when repotting the mix you are using already contains fertilizer. If it does, don’t start fertilizing until plants start looking a little light in color. If no fertilizer was added to the potting mix, you can use a half strength liquid fertilizer every 2 weeks or so from mid-March until about mid-October.

Plants bloom best when slightly pot-bound. Often the plant can be lifted once a year and then groomed and reset back into its original pot with some fresh potting media or in a slightly larger one. Remove spent flowers to encourage more flower buds to form.

Sometimes cyclamen mites, spider mites or root rots can be a problem so pay attention to your plants and see that they are receiving the proper care. Always isolate new plants for 30 days before introducing to your collection.
