Our garden expert talks about how to protect shrubs from heavy snow and cold weather in winter, including how to use winter shrub covers.
How to Protect and Cover Shrubs in Winter
Question: Which shrubs should I protect for winter, and what’s the best way to use winter shrub covers? —Robin Evans of Export, Pennsylvania
Melinda:Â Broadleaf evergreens are the most susceptible to winter damage in colder regions like yours. Hemlocks, less hardy and newly planted needled evergreens, and shrubs exposed to drying winds and winter sun also benefit from protection. Create a wind break and a bit of shade with burlap or landscape fabric. Mount the fabric on stakes or posts placed on the windy and sunny side of the plants. Other options include decorative fencing, a plain old snow fence, a pop-up plant protector or a winter shrub cover.
Give tender plants extra TLC. After the ground freezes, apply winter mulch to grafted hybrid tea roses, borderline hardy plants—or anything that may need a little help through the winter—by piling on evergreen boughs, weedfree straw or marsh hay. After the holidays, discarded Christmas trees also provide welcome shelter for birds and create windbreaks for broadleaf evergreens. Place the discarded tree so that it blocks the wind from sensitive plants. Further reduce winter damage to shrubs by keeping them healthy throughout the growing season. And water your shrubs thoroughly before the ground freezes.
Never plant these invasive shrubs (and what to grow instead!)
Winter Storm Damage on Trees and Shrubs
Don’t shake ice and snow off your plants. Doing this can break branches, causing even more damage than the nasty weather already has. Prevent splitting and broken branches on arborvitae and other upright evergreens by loosely tying their stems together with cloth strips or canvas strapping. If you’re exposing berries for birds, brush off the snow gently.
Remove damaged branches when weather permits. Snow and ice storms can take a heavy toll on even the hardiest, best-established trees and shrubs. A broken bough dangling over a sidewalk or driveway is a recipe for disaster, so when you can do so safely, cut it off.
In the future, save yourself some work by planting new landscape additions in areas where they’ll be protected from these extreme cold weather conditions. Plants perform best on the east side of a house or building where they take advantage of the afternoon shade.
