How Much Mulch Do I Need?
- Don't mulch right up to the base of trees, leave a gap. Voles love the cover of mulch to get to the bark of trees.
- Don't mulch more than 2-3 inches high around trees and shrubs.
- Don't volcano the mulch around trees. It look silly and will suffocate the roots systems. Mt. Saint Helen's never spewed out Bradford Pears!
