Knowing when to mow your lawn in the UK is the single biggest factor in achieving a healthy, lush garden. Get the timing right and your grass will reward you with thick, even coverage. Get it wrong — mowing too early, too late, or at the wrong height — and you'll struggle with bare patches, moss, and weak growth. This month-by-month guide is tailored specifically for Norfolk gardens, where our mild maritime climate and sandy-loam soils create unique conditions for lawn care.
Understanding Norfolk's Climate and Grass Types
Norfolk sits in one of the driest counties in England, receiving around 650mm of rainfall annually — well below the national average. East Anglia enjoys relatively mild winters and warm summers, which means the growing season can start earlier and finish later than in northern regions.
Most Norfolk lawns feature a blend of perennial ryegrass and fescue — hardy varieties that cope well with our free-draining soils. Some older, established gardens in areas like Thorpe St Andrew and Eaton may have finer bent grass lawns that need slightly different care.
Month-by-Month Lawn Mowing Guide for Norfolk
January & February — Leave It Alone
Grass is dormant. Don't mow. Walking on frozen or waterlogged turf causes compaction that takes months to recover from. Use this time to service your mower, sharpen blades, and clear debris from the lawn surface.
March — The First Cut
In Norfolk, grass typically starts growing in mid to late March when soil temperatures reach around 6°C. Set your mower to its highest setting (around 4cm) and give the lawn a light trim on a dry day. This first cut removes the winter tips and encourages lateral growth.
🌿 Pro Tip
Never remove more than one-third of the grass blade length in a single cut. Cutting too short stresses the plant and invites moss and weeds.
April — Weekly Mowing Begins
Growth accelerates through April. Begin mowing weekly, gradually lowering the cutting height to around 3-3.5cm for standard lawns. This is also an excellent time to apply a spring feed and treat any moss with ferrous sulphate. April is also when hedges start shooting up — read our hedge trimming guide to stay on top of both.
May & June — Peak Growth Season
This is when your lawn grows fastest. You may need to mow twice a week during warm, wet spells. Maintain a height of 2.5-3cm for a neat finish, or keep it at 3.5cm if your lawn gets heavy use from children or pets. If you're finding it hard to keep up, our lawn mowing service takes the hassle out of regular cuts.
July & August — Drought Management
Norfolk summers can be dry. If there's been no rain for two weeks, raise the mowing height to 4cm and reduce frequency to every 10-14 days. Longer grass shades the soil, reduces evaporation, and keeps roots cooler. Never mow a drought-stressed lawn — the brown colour is dormancy, not death, and it will recover when rain returns.
🌿 Pro Tip
During dry spells, leave grass clippings on the lawn. They act as a natural mulch, returning moisture and nutrients to the soil.
September & October — Autumn Recovery
Growth picks up again as autumn rain arrives. Resume weekly mowing and gradually raise the height back to 3.5-4cm. September is the perfect month for overseeding thin patches, aerating, and applying an autumn fertiliser. Clear fallen leaves regularly — they block light and encourage fungal disease. If leaf fall is heavy, a professional leaf removal service saves hours of raking and protects your lawn through winter.
November — The Last Cut
Give the lawn a final cut in early to mid November on a dry day, setting the mower to 4cm. This tidies the lawn for winter without scalping it. After this, clean and store your mower properly.
December — Rest Period
No mowing needed. If there's an unusually mild spell and the grass is clearly growing, you could give it a very light top with the mower on its highest setting, but this is rare in Norfolk.
When to Mow Your Lawn UK — Quick Reference
- First cut: Mid-to-late March (when soil reaches 6°C)
- Peak mowing: May-June (twice weekly in ideal conditions)
- Summer drought: Raise height, reduce frequency
- Last cut: Early-to-mid November
- Winter: No mowing December-February
Mowing Height Guide
- Standard family lawn: 2.5-3.5cm during growing season
- Fine ornamental lawn: 1.5-2cm (requires more frequent cutting)
- Shaded areas: Keep at 4cm+ (longer grass captures more light)
- First and last cuts of the year: 4cm
- During drought: 4cm minimum
Common Lawn Mowing Mistakes
Even experienced gardeners make these errors:
- Mowing wet grass — causes uneven cuts, clumping, and can spread disease
- Scalping the lawn — cutting too short weakens grass and lets weeds in
- Using blunt blades — tears rather than cuts, leaving brown tips
- Mowing in the same direction every time — creates ruts and grain patterns
- Starting too early in spring — walking on wet, cold turf damages the root structure
🌿 Pro Tip
Alternate your mowing direction each week — vertical one week, horizontal the next. This prevents the grass from leaning in one direction and gives a much more even finish.
A well-mowed lawn is the foundation of any great Norfolk garden. Whether you're maintaining a small courtyard in Norwich city centre, a sprawling plot in Sprowston, or a village green-style garden in Aylsham, these timing and height guidelines will help you achieve a lawn you're proud of throughout the year. For a fully hands-off approach, our garden maintenance plans include regular mowing, feeding, and seasonal care.
