Recently we got several loads of mulch from an arborist working in the neighborhood. Mulch is made of trees or branches chipped into small pieces and spread over paths or flower beds. There are many benefits of doing this. Mulch holds moisture in the soil preventing evaporation and mulch prevents weeds from sprouting. It also breaks down over time turing into organic matter that provides other benefits to the soil. This mulch is from pine trees and smells really good!
