Grass clippings: mulch or bag?
Short answer: mulch, almost always. Clippings are mostly water and nitrogen — leaving them on the lawn returns the equivalent of about one free fertilizer application per season. But there are real exceptions, so here's the full picture.
The thatch myth
The most common reason people bag is fear of thatch buildup. Clippings don't cause thatch — thatch is made of slower-decomposing stems and roots, while clippings break down within days. (If you do have a spongy thatch layer, that's an aeration and dethatching conversation, not a bagging one.)
When mulching wins
- Any regular cut following the one-third rule — short clippings disappear into the canopy
- Hot, dry stretches — the clipping layer slows soil evaporation
- Every week you'd rather not pay a bagging fee
When bagging actually makes sense
- Overgrown lawns. Heavy, clumping clippings smother grass — bag the rescue cut, then mulch after
- Active lawn disease. Bagging limits spreading fungal spores around the yard
- Fall leaf mix. Sometimes a mow-and-bag is the fastest cleanup pass
Homigo mulches by default and bags on request — and our crews will flag it if your lawn hits one of the bag-it situations above. See what every mowing visit includes.
