What to do in the garden in early February
Do cut back woody shrubs To stimulate lush new growth on plants like Mexican bush sage, artemisia and butterfly bush cut back to within a few inches of the ground. Don’t use this approach on lavender or ceanothus, though, only lightly prune them after blooming. Prune fuchsias back by a third and remove dead, crossing branches and interior twiggy growth. Container fuchsias can be cut back to the pot rim.
Do Cut back hydrangeas if you haven’t already done so and apply a soil acidifier if you want the flowers blue. Although sulfur is the traditional favorite for quickly acidifying soil it is not as kind to many beneficial soil microorganisms. Coffee grounds, pine needles, peat moss and cottonseed meal are kinder to your soil.
Don’t cut back grasses yet if you get frost in the area where they grow.
Don’t prune spring flowering shrubs and trees like lilacs, Flowering cherries, plums and crabapples, rhododendrons, azaleas, camellias, weigela or spirea until after they flower.
Wait to prune back perennials that may have their new foliage damaged in a late frost.
Prune frost damaged shrubs if you can tell how far down the die back goes, otherwise wait until growth starts in the spring.
