Thickly Mulch Around Trees to Help Retain Moisture
Laying wood-chip mulch around trees and garden beds is a great way to retain moisture and add more organic material to the soil. But too much of a good thing is often a bad thing—and mulch is a prime example. When adding mulch around a tree, avoid creating a “volcano” shape at the base. If the mulch is too close to the tree trunk, the bark will remain overly wet, inviting pests and disease. Instead, create a donut shape, with the mulch tapering down to nothing at the tree’s base. This practice will allow for airflow while suppressing weeds and retaining soil moisture.
