Most cool-season and warm-season lawns look best when you follow the “one-third rule”—never remove more than one-third of the blade height at a time. In active growth, that typically means weekly mowing; during slower periods, you can stretch the interval.
- Target heights: Kentucky bluegrass 2.5–3.5", tall fescue 3–4", bermuda 1–2".
- Keep blades sharp to reduce turf stress and browning.
- Mulch clippings to recycle nutrients and improve soil.
- Adjust frequency with weather—more often after rain/heat spikes.
