Most winter damage is not caused by the cold, but by the wind and sun in late winter, when the soil is deeply frozen. Sensitive evergreens, such as Alberta Spruce, Berkmans cedar, and Hinoki cypress, which are susceptible to dehydration, should be wrapped with a covering of burlap. Do not use plastic.
Upright evergreens require protection from the weight of snow and ice.
Vexar Mesh or twine can be used to pull the branches in firmly. Delicate broad-leaved evergreens, such as Rhododendron, Pieris and Laurel, require special consideration. Apply a thick layer of leaf or bark mulch over the root area. Create a shelter around plants using four stakes and burlap as a covering. All evergreens should be well watered prior to freeze up to limit dehydration.
