Are you planning on spreading mulch around your trees and landscape this year? Master Gardener Volunteers see this common practice of mulch placed under trees and right up the tree trunk!
Another mulch volcano! That is a big NO, NO! It’s important to keep mulch off the tree trunk because the covered tree trunk will grow roots under the mulch. As the new roots grow in the soft mulch, the deep roots begin to die off. Eventually, a tree with a weak root system could be blown over by a strong windstorm.
For more information on mulching trees see this excellent article written by Joe Boggs that can be found on the OSU Buckeye Yard & Garden onLine (BYGL), https://bygl.osu.edu/node/1494.
