Suppress weeds by blocking out sunlight.
Helps prevent tree trunk injury by mowers and line trimmers.
Plants should be mulched as needed to maintain a 2 to 3-inch layer. Keep mulch at least two to three inches away from the stems and trunks of plants. When mulching individual trees planted in lawns, create a circle of mulch about 2 feet in diameter for each inch of trunk diameter. Measure the trunk diameter 6 inches up from the ground. Increase the size of the mulched area as the tree grows, extending up to or beyond the dripline or outermost reaches of the branches.
