First the age old question: Should I remove snow from my plants? Most of the time it is not necessary. Sometimes, not advisable. If temps are below 20ºF you will break branches easily. If you just can’t take it, use a broom and gently knock off snow while it is fresh. But this may cause more harm than good to your plants as well as to yourself. Learn more from the Chicago Botanic Garden blog, “Snow Removal from Shrubs?”
Snow can also beneficial to plants. It acts as a layer of insulation during friged winter temps and harsh winter wind while providing moisture and nutrients. Learn more from Purdue University Extension: Snow is Good and from Friends of the Garden: Snow contains nutrients.
