Leaf Mold - Time and Process

Time and Process

Leaves alone can take between one and two years to break down into rich humic matter with a smell reminiscent of ancient woodland. While not high in nutrient content, leaf mold is an excellent humic soil conditioner. To speed up the decomposition process, fallen leaves can be shredded, for instance by using a rotary lawn mower. Adding fresh grass clippings to autumn leaves will also speed the process. For best results watch the pile to keep moisture content high enough, observe temperatures, and turn the pile occasionally to improve the cycle.
