Do plants require winter protection?

In our climate, perennials and hardy shrubs are usually protected by a deep snow cover, which is the best form of winter protection. They usually do not need to be tightly covered with jute or plastic. However, protection is required for less hardy or for grafted plants, as it compensates for abrupt changes in temperature. Install protection in mid to late November, once plants are dormant after a few consecutive days of temperatures between -5°C and -10°C. Remove it around mid-April, once the ground has thawed.
