- GOOD – proper mulching is good for trees. It helps soil hold water, fertilizes soil, and protects the bark from mowers and string trimmers.
- BAD – Too much mulch is bad for trees. NO MULCH VOLCANOES!
- Mulch mounded up on the trunk in the shape of a volcano is bad because it softens the bark and causes it to become susceptible to insect, fungus, and rodent infestation.
- HOW TO APPLY – Start 6 inches from the tree trunk at ground level and mulch outward to the edge of the drip-line to a maximum depth of 2-3 inches.
- OLD MULCH – remove crusted mulch before adding new mulch
Newly planted tree:
- Provide the tree with one inch of water per week (in addition to the water provided by any lawn sprinklers)
- Water trees 3-5 times a week during the first few months of planting, if there is no heavy rain.
- Remove all supporting stakes from around the tree on year after planting.
- Keep all mulch at least 4 inches from the bark of the new tree and not more than 2-3 inches deep.
- Refrain from planting perennials and bulbs within 10 feet of the new tree
Mature, established tree:
- The above procedures should be followed especially during prolonged dry periods.
- Refrain from attaching any objects to a tree such as a sign, flag, mailbox etc.
- Refrain from planting perennials and bulbs within 10 feet of the base of the tree.
