We’ve already had a tiny bit of snow here on the Island. The light kind of snow that melts as soon as it hits the ground and is prettier to look at than worrisome. However, with winter just around the corner—and an abundance of storms predicted—it pays to go over what to do about your trees and shrubs after a heavy snowfall.
Heavy wet snow can cause damage to delicate young trees and shrubs. The weight of snow can break branches or split them, and some may even be uprooted if the snow is heavy enough.
During most snow and ice storms, you won’t have to do anything to your trees and shrubs. Nature is pretty good at taking care of itself, but once in a while, it can use a helping hand. While a light covering of snow won’t do any damage, if you see branches—or in the case of some shrubs like arborvitae, the whole plant—being pulled to the ground by the weight of the snow you may want to get some of the snow off before the branches or trunk snap under the weight. If a plant tips you’ll have to wait until spring to right it, and once you do you should stake it with supports for at least a year or two so that it can regrow a strong root base.
It is best to remove the snow before it freezes over as removing the snow which has frozen to the plant can cause more damage than you’ll save by getting it off. Branches can be more delicate than they look and when already weakened by the weight of ice and snow they can snap off easily.
If branches have already broken, there isn’t much you can do to save them. It’s best to just leave them until spring to prune. However, if the branch is a safety hazard you should trim it right away or call a professional like Organically Green Horticultural Services to come and take a look at the damage, assess it, and find the best solution for the health of the plant.
