Flowers and Groundcovers:

- See UMD’s HGIC’s December Flower tips for more details.
Trees and Shrubs:
- Prune maples, dogwoods, birch, elm, walnut, and yellowwood to prevent “bleeding”.
- Water slowly and deeply if weather is very dry.
- Prune out Fireblight damage Malus and Pyrus when very cold.
- Mulch or compost healthy leaves.
- If your conifers start shedding their needles or your spring bulb foliage starts peeking out of the ground, don’t worry. This is normal for our autumn cycle.
- Prune evergreens to get in shape for fall/winter.
- Prune and thin shrubs that have already flowered.
- Water newly planted trees and shrubs weekly or as needed.
- Pests to watch for: adelgids, aphids, scale, sawfly, spidermites, and voles.
- Diseases to watch for: Fireblight
- See HGIC’s December Trees and Shrubs Tips for more details.
Herbs, Veggies, and Fruit:
- Protect fig trees from freezing by piling up leaves around them.
- Prune out Fireblight damage on apples and pears when very cold.
- This is a good time to have your vegetable garden and landscape soils tested.
- Preserve gourds and dry flowers for display in the fall.
- Watch for insect and disease problems throughout your garden.
- Pests to watch for: asparagus beetle, aphids, cabbage worms, corn earworm, and cutworms
- Diseases to watch for: Fungal, bacterial, viral diseases
- Here are some more fruit and vegetable gardening tips for December from UMD’s HGIC.
- Have soil tested (every 3 years minimum).
- Fertilize your lawn and reseed if needed.
- Apply fertilizer and lime to turfgrass based on soil tests and UME recommendations.
- Rake leaves, shred, and gather in compost piles.
- Turn your compost pile weekly and don’t let it dry out. Work compost into your planting beds.
- Diseases to watch for: brown patch, and red thread
- Pests to watch for: Grubs
- See HGIC’s December Lawn Tips for more details.
- Clean the leaves of your indoor houseplants to prevent dust and film to build-up.
- Set up a humidifier for indoor plants or at least place them in pebble trays.
- Reduce fertilizing of indoor plants (except cyclamen).
- Rotate houseplants to promote even growth.
- Do not place live wreaths or greenery in-between your door and a glass storm door, especially if the doorway is facing south. This placement will “cook” the arrangement on a sunny day.
- For readying Christmas cactus and poinsettias for holiday blooming, see holiday blooming tips: Poinsettia Plant Care, Holiday Plant Care
- Remove old leaves, damaged stems.
- Fertilize houseplants now that they are actively growing again.
- Repot root-bound houseplants and start fertilizing them.
- Pests to watch for: aphids, spider mites, and whitefly
- See HGIC’s December Houseplants Tips for more tips.
Indoor/Outdoor Insect and Wildlife Tips:
- Keep bird feeders filled for birds in the winter.
- Vacuum up any ladybugs that come in the house.
- Don’t put your birdbath away. Birds need fresh water for drinking and bathing throughout the fall season. Clean frequently and keep filled with fresh water.
- Check for vole problems and set up traps.
- Switch your deer deterrent spray.
- See HGIC’s December Insect Tips for more details.
- Watch for: carpenter ants, flies, stink bugs, termites, rabbits, raccoons, groundhogs, deer, moles, snakes, squirrels, and voles.

Plant Clinics are held at several sites in the county on a weekly basis and at special events such as garden festivals and the county fair. Regularly scheduled Plant Clinics are located at public libraries and farmers’ markets throughout the county as well as at the Audubon Naturalist Society in Chevy Chase. There are also clinics three days per week at Brookside Gardens. The busiest season is April through September, but some clinics are open year-round. Bring your plant samples and questions to one of these locations in Montgomery County, MD (see link below to find a location near you):
Maryland Flying Squirrels are abundant, cute, and active year-round, but few see them in the wild because they are active at night – nocturnal. BNC has established a squirrel feeding station so some of our flying squirrels can be seen close up by our visitors. The program starts on the Nature Center deck 30 minutes after sunset to allow the sky to darken. Rain or snow cancels the program.
