Sometimes it’s tricky to tell what’s too much, not enough or just right for our trees.
Take mulching, for example. It’s a must for proper tree maintenance, but when mulch is too high and touches a tree’s trunk, it can cause problems.
Let’s look what can happen when you apply mulch that’s too thick around trees.
To be clear, mulch is great for trees (when it’s applied correctly). Mulch reduces weeds, conserves moisture and improves the soil, which helps your tree stay healthy!
But when it comes to mulch, it is possible to have too much of a good thing. Piling mulch too high and covering a tree's trunk, also known as “volcano mulching,” can cause decay.
When mulch is too high and sits too close to a tree’s trunk, it causes two main issues that can slowly damage your tree over time.
Luckily, preventing these problems is as easy as mulching your tree the right way.
