Inland Northwest, High Desert
Check for Frost-Heaved Plants
Take a walk through the garden but stay on the paths and look at the base of perennials and small shrubs. If the freeze/thaw cycle has tossed them up high enough to expose roots or grafts, cover them up again with more soil or mulch.
Prune Trees and Shrubs
These sunny, dry days are a good time to prune trees and shrubs (except for roses). You can see branch structure and the overall shapes of your plants now. Remember to always cut back to a branch origin and never leave stubs.
Order Seeds and Plants
He who hesitates goes without, especially when it comes to early spring catalog orders. Growers have only a limited quantity of each plant or seed, and this is when the early bird gets the goodies.
Pull Some Weeds
Thought you could weed only in spring, summer, or fall? Give a clump of crabgrass a pull on one of these sunny winter days. You'll be pleasantly surprised to see how the freeze/thaw cycles have loosened the soil for you, making the pulling barely a tug.
Broccoli, cabbage, cauliflower, kale, and onions can get a head start indoors now. The Garden Writers of America urges you to plant a little more than you need and give the excess away. The campaign is called, "Plant a Row for the Hungry." Any fresh produce that you can take to your local soup kitchen will be more welcome than you can imagine.
