Speeding up Leaf Mold

Leaf mold differs from compost in that it provides very little actual nutritional value to the soil…so why bother with it at all? Well it’s main benefit is that it is great at improving the structure of your soil. This in turn helps the soil retain water (and other nutrients) and provide a good environment for beneficial life such as worms, bacteria and other organisms.

Unlike compost, which can be a fickle process to get right, making leaf mold is pretty simple. Just sweep up your leaves and dump them in a pile in a shady corner of the garden and let nature do it’s work. The only down side is that it can take a while (up to 2-3 years) for a pile to break down fully from whole leaves to a fine mold texture.

One simple way to speed up the process dramatically is to reduce the size of the leaves before you add them to the pile. If you’ve got a garden shredder you can simply pass your freshly swept leaves through this.

My technique to speed up my leaf mold is to sweep the leaves into a long line on a patio or path and passing over them with a lawn mower. Doing so only takes a few minutes and the end product is a leaf pile that is already partially broken down.

Using this technique I find that the leaf mold is perfectly useable by the following summer. I use the resulting leaf mold both as a mulch as well as a general soil improver which i dig into the vegetable beds are sprinkle over established beds throughout the year.
