Too Much Mulch Can Damage Your Trees
We've all seen it. You drive by a freshly mulched property, notice that distinct smell of fresh mulch, and take a closer look at the newly mulched flower and tree beds. To an untrained eye, you might see an appealing bed with a tree and a few other smaller plants. The trained eye, however, cannot look past the glaring danger that is commonly referred to as "volcano mulch."
The term "volcano mulch" is used to describe excessive mulch along the root flare and base of a tree, which ends up looking very much like a volcano.
Mulch against tree bark holds in excess moisture. This moisture suffocates and rots the inside layers of tissue cells (xylem/phloem) that transfer food up and down the plant.
Commonly found issues with "volcano mulch":
- Trees weakened and stressed by moisture/rot issues are susceptible to insects, fungi and bacteria.
- Increased growth of unwanted suckers which will weaken structural development.
- Water is prevented from penetrating to the tree’s roots and weak secondary roots will cause strangulation.
How to Mitigate Risks of Volcano Mulch
If your trees have been "volcano mulched" on a regular basis there could be substantially damage caused. A solution that we recommend for improving the health and reviving "volcano mulched" trees is air spading. This safe, effective, and economical solution is the best way to remove excess amounts of mulch without causing harm to the tree. Air spading will reduce soil compaction and help expose the root flare as nature intended. Your tree will no longer be stressed and look like a "volcano."
