Know Your USDA Zone -- It's vital information, since plant label and catalog descriptions usually list which zones a plant grows best in.
Houseplant Basics -- Houseplant growth this month is slow, so don't fertilize and keep watering to a minimum. For more information, check out our houseplant guide.
Forced Bulbs -- Check on pots of any bulbs you forced late last fall. Most forced bulbs need 12-15 weeks of chilling. Remove them into warmth and sunlight indoors when the tips are 1-2 inches high and/or roots are growing out of the drainage holes
Start Seeds Indoors and Last Frost of the Season -- Start seeds indoors for the very slowest-growing plants, such as parsley, thyme, tarragon, bedding geraniums, and sage. You can also start seeds for the plants you can put outdoors early, well before your region's last frost, including chives, onions, and leeks.
Bird Feeding -- If you've been feeding birds, continue to do so and check feeders to make sure they haven't become clogged. Also, fresh water is important this time of year. Consider adding a heater to your birdbath.
Stored Plant Roots -- Check on any stored plant roots or corms, such as dahlias, tuberous begonias, cannas, or glads, for shriveling or decay. Throw out any that are damaged.
Garden Journal -- If you haven't already, start a garden journal or file. Tuck into it names of plants you like, magazine pictures, plant labels and seeds, and anything else that suits your fancy. If you're feeling crafty, make your own journal.
