Are You Using Too Much Mulch?

Are you using too mulch? Use the right amount for the most benefits!

It is possible to have “too much of a good thing”. While using mulch is one of the best things you can do for your yard, sometimes enough is enough! Let’s talk about how much mulch you should be using and what happens if you use too much mulch.

Why should I use mulch?

Mulch is used for many reasons: inhibit plant diseases, reduce weed growth and soil erosion, regulate soil temperature, and improve aesthetics. In order to reap all of these benefits from using mulch, you have to make sure you use the correct amount and you do not under-mulch or over-mulch.

What happens if you over-mulch?

Many people think about all the benefits of mulch and think that the more they use, the better. Unfortunately, too mulch can not only hinder the progress of your landscaping, but it can also damage your plants and landscaping. There are a few things that can happen when you use too much mulch.

  1. Your soil and plants require water, but if your mulch is layered to thick, that water will never reach the soil underneath–leaving your plant roots to dry out and die.
  2. Soil and plants also need air to survive. If you are using too much mulch, you will essentially suffocate the soil and the plant roots below.
  3. Volcano mulches, or excessive mounds of mulch around the base of trees, can cause the same problems as listed above, but they can also attract unwanted pests. You will also start to see decay around the tree, which can cause it to become unstable, creating a safety hazard.

How much mulch do you need?

To calculate the quantity of mulch needed for a project, measure the size of the area in feet. Take this amount and divide by 100 to gain the number of yards you need to cover that area, 3 inches deep. For example, an area 10′ by 20′ would be 200 square feet in size. (200/100 = 2). In this case, as with all our products, you would need 2 yards, which would cover 3 inches deep.
