Just because itās winter doesnāt mean you canātāor shouldnātāget into your yard and garden. In the North, itās mostly about protecting your lawn, garden, and landscape from harsh winter conditions.
Prune the correct deciduous trees and shrubs. Some deciduous trees and shrubs benefit from dormant pruning in winter, others not so much. You can give most deciduous trees a major prune in late winter or early spring but check the shrub āpruning restrictionsā below before making your first cut.
DO NOT! prune spring-flowering shrubs, such as lilac, forsythia, honeysuckle, and mock orange, because they bloom on the wood produced last summer. Youād be cutting offspring buds! Prune these shrubs in spring after they bloom.
Summer-flowering shrubs, including hydrangea, rose, Japanese spirea, and smokebush produce flower buds on new growth and should be pruned now on dry, mild days while theyāre dormant or in early spring before buds begin to open. For a list of spring- and summer-blooming shrubs in your area, check with your local university extension.
Mulch. Borderline-hardy perennials and bulbs can be mulched to provide insulation after the ground is frozen to help prevent the freeze/thaw cycle, which can damage plants. If thereās a blanket of snow, your work is done. If not, recycle the evergreen boughs from the holiday garlands or tree, or cover the garden with straw. Remove winter mulch in spring when the danger of a hard frost has passed.
Deicing. Regular deicing salt can damage plants and when you shovel the most recent layer of snow, youāre tossing residual salt on your lawn and landscape. Instead, use the smallest effective amount of a plant-friendly deicing compound. You may even consider using sand, kitty litter, or birdseed for traction.
Keep Out! If critters are a problem in your yard, maintain barrier fences, which may have shifted from wind and snow.
Rescue plants from heavy snow. Plants can easily be weighed down by heavy snow. Remove the snow to help prevent branches from permanently sagging or snapping off. If the snow has already frozen, let it melt.
Donāt tread on me! Dormant or frozen lawns can easily be damaged and possibly killed by foot-traffic, landscaping equipment, and parked cars, as frozen grass blades contain ice crystals for protection and can break.
