How to dispose of grass clippings often has a surprising answer: you may not need to. Leaving clippings on the lawn, sometimes called grasscycling, returns nutrients and moisture to the soil and saves bagging time. When you do need to collect them, clippings can be composted, used as a thin mulch, or put out for yard waste collection. Several states and many cities ban yard waste from regular landfill trash, so check before bagging clippings with garbage.
Leave them on the lawn
Short clippings break down quickly and do not cause thatch, a common myth. To grasscycle well:
- Mow often enough to cut no more than about a third of the blade at a time.
- Use a sharp blade, or a mulching mower.
- Mow when the grass is dry so clippings scatter.
- Rake or mow again if clumps form.
Compost
Grass clippings are a nitrogen-rich “green” material. Mix them with dry “browns,” such as leaves, straw, or shredded paper, to avoid a slimy, smelly pile. A rough mix of more browns than greens by volume works well.
Mulch
Dry clippings make a free mulch for vegetable beds and around shrubs. Spread them in thin layers, about an inch at a time, so they do not mat and smell. Let fresh clippings dry first.
Yard waste collection
| Option | Notes |
|---|---|
| Yard waste cart | Common in many cities; often seasonal |
| Paper yard waste bags | Required in some areas instead of plastic |
| Yard waste drop-off sites | Accept clippings, sometimes free for residents |
| Regular trash | Banned in some states and cities |
Some yard waste programs ask for clippings to be kept separate from brush.
Herbicide-treated clippings
Some lawn herbicides persist in clippings and can harm sensitive garden plants like tomatoes and beans even after composting. Follow product labels, which may advise against composting or mulching with treated clippings for a set period.
What not to do
- Do not blow clippings into the street or storm drains. They carry nutrients into streams and lakes, feeding algae blooms. Many cities prohibit it.
- Do not dump clippings in woods, creeks, or vacant lots.
- Do not pile thick, wet clippings against trees or buildings.
Hauling large amounts
Wet clippings are heavier than they look and can overload a pickup or rental box. Let them dry if possible. See wet yard waste in a rental box.
