Winter is almost here, and we can feel it with the chilly weather, frosty mornings,
and frigid nights. It’s time to round down our time in the garden outdoors, put up
our tools, and turn to our indoor plants for greenery.
With plenty of leaves still changing their beautiful fall colors and falling to the
ground, we must remember get out and rake excessive leaf matter so not to smother
the underlying plants.
Wondering what kind of garden chores you can do this time of year? Check out what chores we recommend doing this month:
Do you have a maple tree? Wrap trunks of young red maples and other thin barked plants to prevent southwest winter injury.
Cover vegetables and other plants when the temperature drops 28°F or below with an overturned box or large flower pot. When plants are frozen, avoid touching them until the temps are above freezing again. If snow is weighing down your plant, gently remove it to lighten the load. Do not prune damaged leaves, as this will expose more of the plant to the cold. Avoid pruning until February.
Want to decorate your house with greenery from the garden? You can take cuttings of holly, magnolia, and other evergreens. Be sure to prune carefully to avoid hurting the tree, and prune lightly so you don't over-prune. Take pieces from all over the plant to keep it natural-looking.
Do you have a live Christmas tree? Be sure to give it plenty of water.

Depending on how mild the weather has been, you may still be seeing some warm-season vegetables. If they are still producing, continue harvesting, and if they are spent, be sure to remove them and toss them in the compost. If you are wanting to plant some cold-season vegetables, here are a few things you can plant in your garden this month:
Looking for some winter color? Sasanqua camellias, deciduous hollies, and hellebores (a.k.a. Lenten rose) are extremely showy this time of year. These will need to be planted either in spring or fall, but there are still plenty of ornamentals you can plant in December:
Other popular choices for indoor winter color include poinsettias and amaryllis bulbs.
Once you have planted your winter annuals, you will want to fertilize them monthly.
Mulching Tips: Mulching helps keep the temperature of the soil more consistent, helps retain more water, and keeps unwanted weeds at bay. Avoid heaping up the mulch onto the main stem(s) of the plant to provide airflow. Place mulch 2–3 inches high in your bed and around trees.
When you buy a poinsettia, punch holes in the decorative foil to allow drainage and prevent soggy conditions. Place these beauties in a plant dish to catch any excess water, and provide even moisture for the plant.
Poinsettias love a well-lit spot in bright sunlight. Be sure to place your poinsettia in a place where night temperatures do not drop below 50–60°F. Learn more about caring for poinsettias and other winter favorites in this article on Holiday Gardening and Decorating.
