The Q&A Archives: Painting Trees to protect from the cold

Question: i read an article regarding painting your trees to protect them from the cold. is this necessary to do on all trees and also on a Japanese Maple tree, that i have?

Answer: Some trees are especially prone to sunscald and frost cracks so gardeners will try to protect the bark by painting it white to reflect the sun, or by wrapping it to shade it during the winter. Maples -- including Japanese maples -- would be in this group. In my experience, using a tree wrap is better because the white paint really stands out in the landscape. White paint is used more often in orchards than on ornamental trees. Be sure to remove the wrap in the spring.

Your Japanese maple would also benefit from a year round layer of organic mulch about two to three inches thick, apply it in a flat layer over the root area and do not allow it to touch the trunk of the tree. If it is in a windy location, you might also consider giving it a wind break of some kind.
