How deep should the mulch be around my trees, and what kind is best?

Mulch around a tree should be spread like a donut, not a volcano. Never allow mulch to touch the tree’s bark, and never pile it higher than 3-4 inches. Mulch too deep decreases the exchange of oxygen and carbon dioxide, which can lead to fungal and bacterial diseases. It is best to mulch with wood chips or other coarse organic material.
