Grasscycling

Grasscycling is an easy maintenance technique that reduces a lawn's fertilizer needs, and increases biological activity near the soil surface, resulting in a healthier lawn. A mulching mower or attachment may be needed (requires the removal of excessive thatch).

Grasscycling is the natural recycling of grass clippings by leaving them on the lawn when mowing. Successful grasscycling requires only the kind of attention lawns should have on a regular basis.

Grasscycling

Remove excessive thatch before leaving clippings on the lawn. Although quarter inch of thatch is no problem, a thick layer will keep clippings from reaching the soil.

Mow your grass when it is dry and at the upper recommended cutting level for your type of turf: ideally one inch for Bermuda or other fine-leafed subtropical grasses, and three inches for cool-season turfs such as fescues and ryes.

A sharp blade and frequent mowing will produce finer clippings that will decompose quickly. A mulching mower, or a mower with a mulching attachment is preferable.
Avoid over-fertilizing your lawn. If it becomes too dense with growth, your clippings won't reach the soil to decompose.
 
You may choose to collect clippings every third time you mow, or every other time. If you only collect your clippings occasionally, recycle them as mulch in planting beds or add them to the compost pile.
