Mulching is a basic garden act. It helps trees keep water, control heat, and stop soil loss. Bad mulch work hurts trees. Volcano mulching is a poor method. This text shows risks of volcano mulching, tree harm, and safe steps for mulch work.
The Problem with Volcano Mulching
Volcano mulching piles a thick layer of mulch near a tree’s base. The mulch can reach one foot high. This heavy pile suffocates the tree. The bark loses strength when it sits under the pile. Bugs and decay then attack the soft bark.
Bob Ricard from the University of Connecticut says the heavy mulch can harm both old and young trees. The weight pushes roots into bad spots and helps germs and insects grow. When the bark breaks, the tree’s water and food stop moving well. The tree may soon become weak and die.
Signs of Improper Mulching
Spot these hints early to keep trees safe:
- Dark bark: A tree with a thick mulch pile shows dark, decaying bark at the bottom.
- Roots high above ground: Roots that grow out or above the soil warn of stress.
- Wet, mushy mulch: Mulch that turns wet may hold germs that harm the tree.
Proper Mulching Techniques
Follow these safe mulch steps:
- Clear weeds and grass around the base. This step stops a fight for water.
- Spread mulch two to three feet wide around the tree. Keep it only two to three inches deep. Air must flow around the roots.
- Keep the mulch from touching the bark. Let the mulch thin out to the ground. The bark stays bare.
- Pick good mulch materials like old wood chips or broken bark. They break slowly.
- Note tree size. Big trees with a trunk diameter of 10 inches or more may not need extra mulch.
- Check the mulch often. If the layer grows thick or rots, take some off.
Using these plain steps keeps trees safe. Good care and smart mulch work help trees live long and stay strong. For more help on tree care and mulching, talk with local garden experts.
