How to Mulch Around Your Trees

A common question we often hear from homeowners is, “Should I put mulch around my trees?” The short answer is: yes – but within reason.

Aside from being beautiful to look at, mulch provides a lot of benefits to your trees, especially when they’re young. Benefits include providing a weed barrier, insulating the root zone, reducing evaporation, and adding beneficial nutrients to the soil as it breaks down.

Mulch can be a great addition to your landscape but there are a few things to consider before you dive in.

Mistakes to Avoid When Mulching Your Trees

Unfortunately, you don’t have to drive far to see examples of how not to mulch. Many people assume that “mulching” is nothing more than tossing a load of wood chips at the base of the tree and while the application of mulch is pretty straightforward if it is done improperly it can actually harm your tree, rob nutrients from the soil, and draw water away from important areas.

One of the biggest mistakes homeowners make when mulching their trees is creating a “mulch volcano.” This is where the mulch pile starts out thin at the edges and then gradually increases until it reaches the base of the tree, creating a mound that resembles a volcano with a tree exploding out of the center.

This can be dangerous as rainfall and watering will naturally cause the mulch to become damp over time. Excess moisture in contact with the tree creates the perfect environment for decay and disease that can inhibit growth and possibly kill the tree.

Additionally, mulch piled too thickly can actually block oxygen and water from getting to the root zone (where it’s needed most) causing roots to grow upward and around the tree trunk in search of nutrients. Roots should not be growing into your mulch if they are it’s a sign your pile is too thick.
