Death By Mulch..

Why Too Much Mulch Can Damage Your Trees

As Texans in the Tree Service Industry, we’ve seen it all. Homeowners see spring around the corner and want to start mulching and planting as soon as possible. But when you take a closer look at the newly mulched tree bed, keep an eye out for volcano mulching!

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.

When gardeners, landscape artists or your yard guy help you to begin beautifying your lawn, it’s important to be educated on the do’s and don’ts of mulching.

Too much mulch against your tree bark holds in a ton of moisture. This moisture can suffocate and rot the inside layers of tissue cells that transfer food up and down the plant. If not careful, too much mulch can actually do even more damage such as:

  • Infestation of 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 Do I Fix My Mulch Problem?

If your trees have been “volcano mulched” you may have already caused damage. Luckily, we do have a solution called Air Spading. This is the best way to remove excess amounts of mulch without harming your tree. Air spading will reduce soil compaction and help expose the root flare as nature intended. Your tree will no longer be stressed or look like a “volcano.”

Request a free estimate if your trees have been “volcano mulched” and an Arbor Care, Inc. Certified Arborist will be able to assess the damage and develop a plan for bringing the tree back to health.
