when should you cut grass

You should cut grass during its active growing season, when it’s dry, and only ever take a little off at a time for a healthy, good‑looking lawn.

Quick Scoop

1. Best time of year

  • In most temperate climates, mowing season runs roughly from March to October , once frosts have passed and grass is growing again.
  • Start in early to mid‑spring when daytime temperatures stay above about 6–10°C and the lawn clearly starts to lengthen.
  • Ease off and usually stop in late October or early November as temperatures drop back toward 6°C and growth slows right down.

2. How often you should mow

  • General rule: mow every 7–10 days in the main growing season, adjusting for how fast your grass actually grows.
  • Spring and autumn: every 1–2 weeks, depending on growth.
  • Summer: usually once a week; in hot, fast‑growth spells you might need to mow twice a week, but cut less off each time.

3. Time of day that’s best

  • Aim for late morning to mid‑afternoon , once dew has dried but before the strongest late‑day heat.
  • Avoid early morning when grass is wet (clogs the mower and tears the blades) and avoid the hottest late‑afternoon sun, which stresses the lawn.

4. Seasonal mini‑guide

  • Spring: First cut around mid‑March; start high and mow every 1–2 weeks as growth speeds up.
  • Summer: Mow weekly, never removing more than about one‑third of the blade height, and raise the height a little in drought so the grass doesn’t scorch.
  • Autumn: Reduce frequency to every couple of weeks, with a slightly higher setting as growth slows.
  • Winter: Usually don’t mow; only consider a very light cut if the grass is still growing, the ground is firm, and temperatures are safely above freezing.

5. Simple “when should you cut” checklist

Cut your grass now if:

  1. It’s in the growing season (roughly March–October where winters are cool).
  1. The grass is dry, and it’s late morning or early afternoon.
  1. It has grown enough that taking off up to one‑third of its height will bring it back to your preferred level.

If any of those aren’t true, wait a few days and check again. TL;DR: Cut grass from spring to late autumn whenever it’s actively growing, dry, and tall enough that trimming off up to one‑third keeps it at a steady height, aiming for weekly cuts in peak season.
