Introduction
After a long winter, your lawn might look tired, patchy, or overgrown—but jumping in with the mower too soon can do more harm than good. Timing your first grass cut after winter is essential if you want a lush, healthy lawn throughout spring and summer.
If you’re new to lawn care, don’t worry—this simple guide will walk you through exactly when to mow your lawn after winter, how to do it properly, and what mistakes to avoid.
Most lawns in the UK should have their first cut between mid-March and early April, once temperatures consistently rise above 7°C and the grass starts actively growing.
When Should You Mow Your Lawn After Winter?
The Ideal Time in the UK
In most parts of the UK, the best time to mow your lawn after winter is:
- Mid-March to early April
- When temperatures are consistently above 7°C
- When grass is visibly growing again
Spring weather can vary, so always focus on conditions rather than calendar dates.
Key Signs Your Lawn Is Ready
Before you take out the mower, look for these signs:
- Grass is actively growing (not dormant)
- Lawn looks uneven or slightly overgrown
- Soil is dry enough to walk on
- No frost or waterlogging
If your lawn ticks all these boxes then you’re good to go!
Why You Shouldn’t Mow Too Early
It might be tempting to tidy up your garden early, but mowing too soon can damage your lawn. We don’t recommend mowing your lawn when the grass is wet, frozen, or not actively growing
Here’s why to wait:
- Frozen or wet soil can lead to compaction
- Cutting dormant grass weakens roots
- Wet grass results in uneven cuts and disease risk
How to Cut Grass After Winter (Step-by-Step)
Step 1: Choose a Dry Day
Pick a mild, dry day – ideally late morning or early afternoon when dew has evaporated.
Step 2: Set Your Mower Height High
For your first cut:
- Keep blades higher than usual
- Avoid cutting too short
This protects fragile grass after winter stress.
Step 3: Follow the 1/3 Rule
Never remove more than one-third of the grass height in a single mow. Cutting too much can shock your lawn.
Step 4: Use Sharp, Clean Blades
Sharp blades:
- Give a clean cut
- Prevent disease
- Improve lawn appearance
How Often Should You Mow in Spring?
Once your lawn starts growing:
- Every 1–2 weeks in early spring
- Increase to weekly as growth speeds up
You can also consider eco-friendly approaches like No Mow May, which supports pollinators and biodiversity.
Common Beginner Mistakes to Avoid
Avoid these common pitfalls:
- Cutting grass too early
- Mowing when wet
- Cutting too short (scalping)
- Ignoring mower maintenance
Fixing these habits early makes a huge difference in lawn health.
Extra Lawn Care Tips for Spring

- Water lightly during dry spells
- Remove debris and moss

Consistent care = stronger, greener grass.
