🌳 A Common Mulching Mistake That Can Kill Your Tree
One of the most common problems we see in landscape beds is mulch piled up against the trunk of a tree. It might look clean and tidy at first, but this practice—often called a “mulch volcano”—can actually cause serious damage over time.
When mulch is piled against the trunk, it can:
• Trap moisture against the bark
• Cause the trunk to rot
• Attract insects and rodents
• Encourage roots to grow incorrectly (girdling roots)
• Slowly weaken or even kill the tree
The correct way to mulch:
✔ Keep mulch 2–3 inches deep
âś” Leave a small gap around the trunk so the bark can breathe
âś” Spread mulch out in a wide ring, not a tall pile
Healthy mulching helps retain moisture, regulate soil temperature, and improve soil health—but only when it’s done properly.
If you’ve noticed mulch piled high around your trees, it’s an easy fix that can add years to their life.
