General Seasonal Guide:
Note: Planting seasons vary depending on the climate of your region.

December
Garden essentials: Prune evergreens for holiday decorations. Don't leave pruning stubs! Finish planting bulbs. Force pots of paperwhite narcissus. Continue transplanting.
Lawn care: Do winter fertilization if you didn't complete this task in late November. Rake leaves and litter off lawn.
Gardening Tip: Mulch paths with wood chips to keep feet drier. Ask for a cold frame to extend your gardening season! Be grateful for the blessing of harvests.
January
Garden essentials: Yank vigorous winter weeds. Prune trees and shrubs, removing diseased or storm-damaged wood. Lightly water and fertilize indoor plants.
Lawn care: Sharpen mower blades and tune up mower. Don't walk on soggy or frozen grass. Healthy lawns compete with moss, which infests shady, compacted or stressed turf. Lime won't eliminate moss.
Gardening Tip: Plan your veggies and flowerbeds. Remember to keep any crops rotated.
February
Garden essentials: Early February often brings deep cold. Don't uncover roses, prune or plant when temperatures drop below freezing. On mild days, plant bare-root roses and fruit trees. Midmonth, pull mulch partly away from emerging bulbs and perennials; hunt hidden slugs. Bring pots of hardy bulbs into warmth and light for early bloom.
Lawn care: Starlings pecking at turf help remove soil grubs such as crane fly. Check lawn for standing puddles. Correct drainage, or replace lawn with better adapted ground covers.
Gardening Tip: Start broccoli, cabbage and cauliflower indoors under a fluorescent shop light. At month's end, move starts into a cold frame or sheltered outdoor location to toughen.
