Tree Maintenance

Once a tree has been properly planted in the right location, establishing a suitable maintenance routine is important to lengthen a tree's life, maintain its safety, and improve its aesthetics. Check out the sections below, or view the Landscape Guide for Developers, Businesses and Homeowners for helpful information.

Mulch is valuable for a tree’s health and care. Mulch insulates the soil helping to provide a buffer from extreme temperatures, retains water helping to keep the roots moist, keeps weeds out to limit root competition, prevents soil compaction, and reduces lawn mower damage. Organic mulch such as wood chips or bark pieces is best as inorganic mulch can lead to a variety of problems. For example, rocks will heat up in the summer sun. 

Place 2 to 3 inches of organic mulch around the tree, being sure to keep the mulch from touching the trunk of the tree. Mulch should be at least 3 inches away from the trunk and should extend out 3 to 10 feet depending on the size of the tree. Piling 6 to 12 inches of mulch at the base of the tree trunk is called volcano mulching. This causes CO2 to build up and prevents the tree from completing respiration. As oxygen is depleted the tree will decline.
