Mulch Around Trees
Too much mulch can kill your tree.
It doesn’t take much excess soil to put a tree into a stressed situation. Even just an inch of excess soil around the root collar can hide problems such as decay or root girdling.
While a tree may have been planted properly initially, you can re-create the problems of planting too deep by piling mulch up around the base of the trunk and root collar. You should never mulch up against a tree trunk, as seen in this photo we took recently. Mulch should always be placed in a shallow layer and burm away from the base of the trunk.
