Monthly Tip

Prevent Fruit Tree Sun Burn

Tip description
Painted peach tree at our Martial Cottle Park orchard
Summer sun can bake trunks and branches of trees, especially when pruned to allow light into the tree’s center. Use whitewash to protect the bark from sunburn and subsequent insect infestation. Coat the south/west facing sides of the trunk and the top of main, sun-exposed limbs of all young trees and on older trees pruned to allow sunlight to reach the tree interior. Use white interior latex paint diluted to half strength with water. Apply the paint mixture from the soil surface up the entire trunk (and 2 inches below the surface for newly planted trees). Smaller branches are usually naturally protected by the tree’s leaves.
