Snow can cause damage when it is thrown over plants by shoveling or snowplows. Snow pushed or thrown over plants is denser than natural snowfall and can rip branches from shrubs and small trees. Evergreens, which trap snow, are most susceptible.
Immediately after a snowstorm, gently remove snow from branches that are bending to the ground. Most evergreens bent over by winter snow recover their upright shape in spring. Do not try to crack ice off branches. Wait for it to melt.
Snow can be good for the landscape because it is an insulator against chilling temperatures. Snow on the ground prevents injury to roots, which generally can’t withstand extreme cold. Snow gradually melts and waters the plants during the winter.
Salt injury
Salt draws moisture from plant cells, causing tissue to dry out. This can happen in roots or leaves. Needled and broadleaf evergreens are most susceptible to salt damage because they still have living leaves.
