Recover from Winter
The early cold snap was followed by unseasonably warm weather. Many perennials began growing in December just before another cold front moved in. Hardy, established plants with sufficient energy reserves may suffer some minimal damage, but otherwise be fine. New plantings with less robust root systems could suffer more damage and be slower to emerge this spring.
Fluctuating temperatures also caused the soil to alternate between freezing and thawing, causing it to shift and push some bulbs and perennials like coral bells out of the soil. With this process known as frost heaving, the plant roots are exposed to cold dry air. Walk around the garden and reset any bulbs or perennials that have heaved out of the soil.
Check for rabbits and vole damage on young trees and shrubs. Look for the exposed white wood where these critters have eaten away the bark. If any of the cambia (vessels that transport food and water) remain, the plants will recover. Don’t give up on the plant unless it’s obviously dead or there’s a need— and now an excuse—to replace it with something better.
Prune off any broken or damaged branches. Make cuts above a healthy, outward-facing bud where one branch joins another or the main trunk. Then, shape plants as needed. Wait to prune spring-flowering shrubs like lilacs and forsythias until after their spring floral display. Summer-blooming plants like Japanese spireas and Annabelle hydrangeas can be pruned before growth begins in spring. Remove and compost any leaves and twigs that may have accumulated on the lawn. Use a leaf rake to speed drying of the grass and reduce the risk of snow mold.
Locate vole trails left in the lawn as these critters scurried about in search of food. Gently tamp disrupted grass plants back into place. Plan on reseeding larger areas damaged by vole activity and winter weather in late April or early May.
Monitor the landscape throughout the spring and be patient. It’s surprising how resilient plants can be. Once the damage has been assessed, start making plans for this year’s garden and landscape improvements.
