How to mow the lawn for the first time in spring
The first mow of the season is one of the most important lawn care jobs. Done correctly, it sets your lawn up for thicker growth, fewer weeds, and a healthier appearance throughout spring and summer.
Cut too early or too short, and you can weaken the grass just as it comes out of winter dormancy.
Quick answer: first lawn mow in spring
Mow your lawn for the first time in spring when the grass is dry, actively growing, and around 5–8cm tall. Set your mower blades high, remove only the top third of the grass, and avoid cutting too short.
Step-by-step guide to the first spring mow
Step 1: Wait for the right conditions
- Grass should be dry and actively growing
- Soil should be firm, not waterlogged
- No frost or very cold weather
Step 2: Prepare the lawn
- Remove leaves, twigs, and debris
- Lightly rake to lift flattened grass
- Check for moss or damaged patches
Step 3: Set the mower height high
- Use the highest or second-highest setting
- Follow the one-third rule (never cut more than one-third)
- Keep grass slightly longer early in the season
Step 4: Mow evenly and carefully
- Mow in straight lines for an even finish
- Avoid sharp turns that can damage soft ground
- Take your time — this is a light first cut
Step 5: Finish and clean up
- Leave fine clippings if short (they add nutrients)
- Remove heavy clumps if present
- Clean mower blades after use
When to mow your lawn for the first time
Your first mow should happen when:
- Grass has started actively growing
- It reaches around 5–8cm in height
- Conditions are dry and mild
Mowing too early, especially on wet or cold ground, can damage both grass and soil structure.
