Grasscycling and Eco-Friendly Lawn Care

What if the best fertilizer for your lawn was something you currently bag up and throw away? Grasscycling — leaving grass clippings on the lawn after mowing — feeds your turf for free, saves time, and reduces green waste. Here is how to do it right in Southern California.

How grasscycling works

Grass clippings are about 80% water and rich in nitrogen. Left on the lawn, they break down quickly and return nutrients to the soil — supplying a meaningful share of your lawn's nitrogen needs over a season. They do not cause thatch, a common myth; thatch comes from roots and stems, not clippings.

Doing it right

• Mow regularly: remove no more than a third of the blade at a time so clippings are short and settle into the lawn.
• Use a mulching mower or blade: it cuts clippings finer so they disappear into the turf.
• Mow when dry: dry clippings spread evenly; wet ones clump and can smother grass.
• Keep blades sharp: clean cuts decompose faster and keep grass healthy.

The benefits add up

Grasscycling cuts your fertilizer needs, saves the time spent bagging and hauling, and keeps yard waste out of the landfill. It also helps the soil retain moisture — a real advantage during Inland Empire summers and water restrictions.

When to bag instead

Bag clippings if the lawn is diseased (to avoid spreading it), if it has gone too long between mows and clippings are excessively long, or when overseeding. Otherwise, let them lie.

Frequently asked questions

Do grass clippings cause thatch?

No — that's a myth. Clippings decompose quickly. Thatch is built from roots and stems, not clippings.

Will clippings make my lawn look messy?

Not if you mow regularly and when dry. Short clippings settle out of sight within a day.
