Do you have a tree with a mound of mulch around the trunk? Don’t get me wrong, putting mulch around your tree trunks so the lawn mower does not hurt their bark is a good thing but only when it is 2″ or less of mulch. Many people loose trees and they don’t know why. Over time, having mulch piled up around the trunk causes the bark to rot because of the continued moisture around the bark after the rain. The tree gets its life and nutrients from the bark, so if the bark rots and falls off, the tree cannot sustain itself anymore so it has to die Many good trees have died unnecessarily so make sure they are not your trees!
