Poinsettias
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!
Native Plant Highlight: Ilex verticillata
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
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!
