Reasons Not to Over-Mulch Your Tree

One popular landscaping error homeowners make is putting a lot of mulch around trees. Of course, there’s a reason for this. 

Mulch is a helpful landscaping tool that can improve the curb appeal of your house with its ability to deter weed growth and retain moisture. However, when using it around trees, you have to follow the “less is more” rule, whether you’ve got softwood or hardwood.  

You might notice a couple of issues if you apply to much mulch around your tree. Today, we’re going to talk about why most tree service Port St Lucie recommends the “less is more” approach. 

The Right Amount of Mulch to use 

You’ve got to avoid using a lot of mulch if you want to protect your tree against pests, root rot, and fungal disease. You can still apply mulch around the trunk of a tree. However, you’ve got to apply less mulch.  

An excellent rule to follow is to apply a mulch layer less than 2 inches deep. This should not have a huge influence on the health of a tree at this depth. It will instead offer just enough coverage to improve the aesthetics of your lawn while deterring weed growth in the process.  

If you apply too much mulch, here are a couple of issues you might encounter: 

Pests 

Naturally, insects are attracted to mulch. Thus, it should not come as a surprise to know that utilizing too much around a tree will leave it susceptible to pests.  

You might discover pests creating holes into the tree if you apply too much mulch around the tree’s trunk. Aside from that, you might even notice pests eating the tree. 

Root Rot 

Another reason you should not utilize too much mulch around trees is that it can cause root rot. If your tree is surrounded with too much mulch, your tree might suffer from root rot, even if it is healthy and otherwise green. 

For those who don’t know, there are a couple of reasons why mulch can cause root rot. First, too much mulch traps moisture. This enables rot-causing bacteria to thrive. Second, it limits the roots of oxygen. Obviously, this is required for proper growth and health.  

You need to stop using too much mulch around trees if you want to have a healthy root system. 

Fungal Disease 

Regardless of whether it is surrounded by mulch, the fungal disease can affect any tree. But, you can make your tree more vulnerable to fungal disease if you apply a thick layer of mulch around the trunk of a tree.  

The issue with too much mulch is that it produces nutrient-rick, damp, and dark environment in which fungi can survive. Fungi might infect the tree with any type of disease as it develops in the mulch.  

A couple of fungal illnesses aren’t major. However, some can cause death and a lot of stress. Because of this, you’ve got to avoid applying too much mulch.  

If you’re planning to apply mulch, make sure you ask a professional arborist for help.
