Excessively mulched tree with mulch piled against trunk.
Jan 24, Mulch can damage trees. Too much mulch applied over the root ball or resting against the trunk (see right photos) can cause problems for trees, especially when there is a lagre range in particle sizes.
Roots often grow up and into the mulch causing stem girdling roots which can kill trees (lower photo). This is especially troublesome on trees planted within the last 10 to 20 years. Apr 12, Mulches are available in two major forms, organic and inorganic. Tree care professionals prefer organic mulches, such as wood chips, pine needles, hardwood and softwood bark, cocoa hulls, leaves, and compost mixes, since they decompose, improving soil structure and increasing soil treenotch.barted Reading Time: 7 mins.
