What to Plant:
Annuals/Bedding plants: Masses of petunia, pansy, snapdragon, lobelia, alyssum, and viola add color in winter.
Bulbs: Amaryllis can be forced to bloom now or planted outdoors for spring blooms.
Herbs: Some examples of cool-weather herbs include parsley, thyme, sage, dill, fennel, garlic, comfrey, and cilantro.
Vegetables: Reliable cool-season vegetables include cabbages, collards, beets, and broccoli.
What to Do:
Perennials: Cold damage: Wait until warm weather returns to cut back cold-damaged plants.
Vegetable garden: Make sure that seeds and transplants are properly spaced for good development of tubers and vegetables.
Houseplants: Inspect regularly for pests on indoor plants. Keep in mind that
adequate light is a key factor to ensuring that indoor plants thrive.
Soil test: Consider performing a soil test if plants do not perform as
desired or if new plantings are planned.
Compost/mulch: Use fallen leaves to provide the carbon ingredient needed for successful composting and also to make a good mulch.
Garden pests: Continue monitoring and treat as needed. While cooler weather generally means fewer pests, some populations actually increase at this time of year.
