Distance from Trunk

• As a general practice, mulch should be maintained at least 3 to 5 inches away from the trunk of a young tree and 8 to 12 inches away from older trees. In most cases, it should be spread on the ground to the outer reaches of the canopy or branches. This practice can be of assistance in maintaining moisture in the ground during dry periods, while keeping grass and weeds from growing too close to the trunk and root system.
