Roger - Sunscald can be managed by using commercial tree wraps. These are made of crepe paper and help to insulate the bark. In late October or early November, wrap trunks upward from the base of the tree to a point just above the lowest branches. This is typically done on younger trees until they are able to develop thicker bark to serve as protection. These trunk guards should be of a light color so that they can reflect sunlight during winter thereby reducing the temperature on the bark. Be sure to remove tree wrap and tape the following April to avoid girdling and possible insect damage.
