The benefits of mulch do not end with added moisture and weed control. As organic mulches decompose, they promote healthy soil, which in turn helps fend off disease.
Mulches also regulate soil temperature, acting as insulation to prevent the alternating freezes and thaws that can heave plants out of the ground. Such ground-insulating mulches are especially useful in keeping the roots of newly planted trees and shrubs growing as long as possible into autumn. They also keep the soil beneath evergreens unfrozen deeper and longer so that their roots can absorb moisture in winter. Do you find mulches help your garden through the winter?
