| Tree Mulch Saves Moisture and Trees Applying mulch around a tree is one of the most beneficial things you can do for it. Mulches are materials, such as wood chips and shredded bark, that are placed over the soil surface to help conserve moisture, improve soil conditions, and protect the tree. Apply a layer of mulch 3 - 4 inches deep and as broadly as practical around the tree. Mulch out to the outermost reaches of the branches of younger trees. Keep the mulch 3-6 inches away from the trunk of the tree to help limit rodents from feeding on the bark and prevent bark rot on the tree. Avoid piling on too much mulch and creating "mulch volcanoes" around your trees. |

| If you keep the tree watered, a layer of mulch will help retain moisture. Mulch can also improve soil structure and aeration, keep roots cool in summer and insulated in winter, and help retard weed growth. By limiting weed growth around the base of the tree, you limit the chances of weed whackers and/or lawnmowers damaging the bark and opening the tree to decay, insects, and disease. Repeated injuries from these tools can completely girdle a tree and kill it. | ||||||
