Mulching is an important factor for plant beds to maintain a healthy and aesthetically pleasing landscape. A layer of mulch around plants helps retain moisture, which allows the plant stock to be healthier. A layer of mulch around plants reduces the weed growth and adds nutrients to the soil due to its natural decay.

Middle Tennessee Grounds’ Do’s and Don’ts of Mulching


  • When mulching trees, mulch surrounding the trunk should look like a donut – a uniform circle.
  • Keep the mulch to a thickness of 1-2″ around the base of trees, shrubs and perennials to prevent decay of the bark layer causing poor growth.
  • Overall, keep mulch at a maximum thickness of 4″– any more will restrict the access of oxygen to the soil and plant roots.
  • Try to have an edge for the mulch to sit along to prevent it from migrating out into the lawn.
  • If re-mulching beds, it may be necessary to remove some of the old mulch to allow for proper depth when installing fresh mulch in plant bed areas.


  • Avoid excessive build up of mulch around base of trees and shrubs.
  • Using chipped wood from a local municipality is not recommended for typical decorative plant beds. Using these chips may bring in viral infections that a tree had when removed and chipped; in addition, unwanted growth of saplings will also occur.
  • Do not use mulch over landscape fabric in the hope of improving the soil. When the mulch decompose it cannot enter the soil if there is a fabric barrier between it and the soil. Mulch will also break down creating allowing weeds to germinate above landscape fabric.
