Mulch volcanoes kill trees –
Let’s end their use in Saratoga
Properly applied, mulch helps keep the roots cool, retains soil moisture longer, and suppresses weeds. But it is important to keep the mulch away from the trunk of the tree. No matter how many professionals you see piling mulch into volcanoes around the trunk, don’t follow this harmful practice.
A handy rule of thumb for proper mulching is the 3-3-3 method
: 3” deep, 3” from the trunk, and a radius of 3 feet.
Why should you NEVER pile mulch against the tree trunk in a “mulch volcano?” These weaken and ultimately kill many trees. Mulch volcanoes can suffocate the tree and, by compromising the bark, can open the tree up to attack from fungi, boring insects, mice and other threats. Use the 3-3-3 method for a healthy tree.
