Wood and bark chip mulch protects trees and shrubs from lawnmower damage. However, do not make “mulch volcanoes” around tree trunks by applying chips up against a tree’s trunk.
Wet chips piled up against the trunk can cause bark problems and interfere with the natural trunk taper, making the tree more prone to wind throw. Keep the mulch at the base of the tree and preferably back at least 6” from the trunk.

Please, NEVER pile bark mulch around tree trunks! |
Bark mulch placed below and away from the trunk flare at the base the tree is healthier for the tree. |
