You should usually give your lawn its first cut after winter in early spring, once the grass is actively growing and conditions are mild and dry enough.

Quick Scoop

  • Aim for March as a typical first-cut month in many temperate climates, but adjust for your local weather.
  • Wait until frosts have finished and daytime conditions are consistently above about 6 °C (soil and air).
  • Make sure the ground and grass are dry , so you don’t compact the soil or tear the grass.
  • Start with a high mower setting , removing less than one‑third of the grass height on the first cut.
  • Through spring, gradually lower the cutting height and mow more often as growth speeds up.

When should you first cut grass after winter?

For most home lawns in cool, temperate regions, mowing is normally needed between March and October , with the first cut often falling sometime in March. The exact timing depends on where you live, how sheltered your garden is, and how that particular year’s weather behaves.

Experts note that grass really gets going again when soil temperatures rise above about 6 °C , and mowing should only start once winter frosts have properly passed. In many places, this sweet spot appears from late March to early April , though mild years can shift it earlier and cold springs can push it back.

Key conditions to check before the first cut

Think of it less as a fixed date and more as a checklist:

  1. Temperature
    • Grass growth starts once soil is above ~6 °C , so your lawn should look like it’s slowly growing again.
 * Avoid mowing if nights are still regularly frosty; guidance is to wait until **frost risk has largely passed**.
  1. Ground moisture
    • If the ground is very wet and squelchy, the mower’s weight can compact the soil and damage roots.
 * Let a few **dry days** pass so the surface firms up before you start.
  1. Grass condition
    • The grass should be standing up and not waterlogged or frozen.
 * If it’s long and floppy after winter, the first job is a gentle tidy, not a close shave.
  1. Weather trends
    • A short, mild spell after a cold winter may not be enough; look for a sustained period of milder weather (above ~5–6 °C for a couple of weeks).
 * In unusually mild years, some lawns may grow almost all winter and be ready earlier; in harsh springs they may need longer.

How to do that first post‑winter cut

Once conditions look right, treat the first mow as a reset , not a full makeover.

  1. Set the mower high
    • Raise the blade and remove less than one‑third of the grass height on the first pass.
 * Cutting too low stresses the grass, encourages **shallow roots** , and can leave it more vulnerable to drought, disease, and bare patches.
  1. Choose a dry, later-in-the-day window
    • Cut when the grass is dry to avoid clogging the mower and tearing the leaves.
 * Later in the day is better so **frost has thawed and dew has evaporated**.
  1. Check the ground as you go
    • If you see muddy wheel ruts or the mower sinking, the soil is still too soft and you should stop.
 * On heavier soils, give it extra time to drain before trying again.
  1. Plan the next few weeks
    • After that gentle first cut, you can gradually lower the cutting height over several mows as temperatures rise.
 * Early in the season, mowing every **two weeks** at a higher setting is typical, moving to **every 10 days or weekly** once growth ramps up around mid to late spring.

Different viewpoints and trends

Garden and wildlife groups increasingly encourage a lighter touch with spring mowing to support pollinators and biodiversity. Some people delay the first cut or leave parts of the lawn longer to allow early flowering plants and wildlife habitat to develop. At the same time, lawn-care brands and property advice sites still focus on achieving a neat, lush lawn and suggest starting as soon as conditions are safe and growth is steady.

Climate trends are also stretching the growing season , with grass in some regions growing for more of the year than it used to. That means you might notice your first cut creeping earlier over the years in milder springs, while unusually cold or snowy springs can still delay mowing well into April.

Simple rule-of-thumb

If you want a quick, memorable guideline for when should you first cut grass after winter :

  • Wait until:
    • Frost risk is mostly gone.
* Soil and daytime temperatures sit above ~6 °C for a couple of weeks.

* The lawn is visibly growing and reasonably dry underfoot.
  • Then:
    • Give it a high, gentle cut , taking off under one‑third of the height.

This balances lawn health, appearance, and the changing spring weather patterns.

TL;DR: Start thinking about the first cut after winter around March , but don’t mow until frost has passed, soil is above about 6 °C , and the lawn is dry enough to walk on without sinking—then mow high and gently for that first pass.
