Lawn Care Calendar UK: Month-by-Month Guide

A perfect lawn doesn’t happen overnight. It follows a rhythm — one shaped by the UK’s changing seasons. Knowing what your lawn needs each month helps you plan ahead, avoid common mistakes, and keep your grass thriving year-round. Whether you’re a first-time homeowner or an experienced gardener, this month-by-month lawn care calendar will show you exactly when to mow, feed, repair, and rest your grass.

At The Grass Is Always Greener, we’ve simplified this process with a seasonal subscription kit that aligns perfectly with the British climate. But even if you prefer to DIY your care routine, this guide will tell you everything you need to do — and when — for a lush, resilient lawn.

January — Rest and Protect

January is the quietest month for lawn care. Grass growth is minimal, and soil is often frozen or waterlogged. The main goal now is protection, not action.

• Keep off frosty or muddy grass to avoid compaction.

• Remove fallen branches and debris to prevent mould.

• Clear paths for drainage if puddles appear.

• Service your mower ready for spring.

You don’t need to mow or fertilise in January. Let the lawn rest.

February — Prepare and Plan

By late February, the first signs of growth begin to return in milder areas. This is the ideal time to prepare for the busy spring months ahead.

• Rake away remaining leaves or moss.

• Check for early signs of moss or thatch build-up.

• Sharpen mower blades.

• Plan your first feeding for March.

If the weather is mild and frost-free, you can lightly aerate compacted areas with a garden fork.

March — Wake the Lawn Up

March marks the true start of the lawn care year in most parts of the UK. Temperatures rise, growth begins, and moss or weeds often appear.

• Lightly scarify or rake to remove winter debris.

• Aerate to relieve compaction and improve drainage.

• Apply a spring fertiliser high in nitrogen to boost colour and growth.

• Overseed thin areas once the soil reaches 8–10°C.

• Begin mowing once the grass exceeds 7–8cm, setting blades high (around 4cm).

This is also when your first Greener Garden Kit pack for spring arrives — timed perfectly to repair winter damage and kick-start new growth.

April — Growth and Feeding

April is prime growth season. Consistent temperatures, regular rain, and longer daylight create ideal conditions for lawn improvement.

• Mow weekly, gradually lowering the cutting height to around 3.5cm.

• Spot-treat weeds before they spread.

• Apply moss killer if necessary.

• Reseed bare spots for quick recovery.

• Keep feeding with a balanced spring fertiliser.

Avoid mowing when grass is wet — this can cause clumping and tearing.

May — Thickening and Strengthening

By May, your lawn should be growing strongly. Focus on thickening the turf and preparing for summer stress.

• Continue mowing once a week, maintaining around 3–4cm height.

• Apply a second round of spring feed if growth slows.

• Watch for signs of chafer grubs or leatherjackets.

• Keep soil moist with deep watering once or twice per week.

• Edge borders for a clean, defined finish.

May is also a great time to overseed shaded areas before the hot months arrive.

June — Summer Maintenance

As summer begins, your lawn faces increased heat and use. Prevent stress with careful mowing and watering.

• Raise mower blades slightly (4–5cm) to help retain moisture.

• Water deeply once or twice weekly in dry spells.

• Apply a summer fertiliser with extra potassium to strengthen against drought.

• Avoid heavy feeding in heatwaves.

• Continue light weed control as needed.

Morning watering is best — it soaks in before evaporation and reduces disease risk.

July — Hydration and Protection

July can be tough on lawns due to high temperatures and foot traffic. Your focus should be hydration and gentle maintenance.

• Keep watering consistently, preferably early mornings.

• Mow less frequently and keep grass slightly longer.

• Avoid scarifying or heavy feeding.

• Inspect for dry patches or pests.

• Use a lawn conditioner or tonic to maintain resilience.

If your lawn browns slightly in drought, don’t panic — healthy grass will recover once rain returns.

August — Mid-Summer Recovery

By August, rainfall often increases, giving your lawn a breather. This is a good time to prepare for autumn rejuvenation.

• Continue mowing weekly at 4cm height.

• Reseed any worn areas from summer activity.

• Begin planning your autumn scarifying and feeding routine.

• Keep on top of weeds and moss before cooler weather sets in.

If your lawn looks thin, this is a great transition month to apply your Greener Garden Kit Autumn Pack early.

September — Repair and Restore

September is arguably the best month of the year for lawn improvement in the UK. Warm soil and frequent rain create perfect conditions for recovery and overseeding.

• Scarify to remove thatch and moss.

• Aerate the entire lawn to improve airflow and drainage.

• Overseed generously for a thicker, greener lawn next spring.

• Feed with an autumn fertiliser low in nitrogen, high in potassium to strengthen roots.

• Keep leaves cleared to prevent smothering.

This single month’s effort often defines how your lawn looks for the next year.

October — Strengthen Before Winter

Grass growth slows, but roots are still active underground. Focus on building strength before frost arrives.

• Apply your final feed of the year with an autumn formula.

• Keep mowing until growth stops (usually mid-month).

• Continue clearing leaves weekly.

• Avoid heavy foot traffic on wet soil.

A well-fed autumn lawn will stay greener through winter and bounce back faster in spring.

November — Clean and Protect

As temperatures drop, maintenance becomes light again. Prevent disease and prepare for dormancy.

• Remove debris and remaining leaves.

• Avoid walking on the lawn during frost or heavy rain.

• Store tools dry and serviced for next year.

• Lightly brush in sand or compost over low spots for levelling.

If moss reappears, treat lightly with iron sulphate before winter sets in fully.

December — Rest and Reflect

December is another rest period. Don’t mow, feed, or water unless conditions are unseasonably mild.

• Keep clear of frozen grass.

• Brush away standing snow to prevent mould.

• Review your year’s results and plan next season’s improvements.

This is the calm before the spring growth surge — and the perfect time to subscribe or renew your Greener Garden Kit ready for the new year.

Tips for Consistent Results

1. Follow weather, not the calendar: Seasonal transitions vary slightly between regions — adapt timing to your local climate.

2. Feed four times a year: Once per season is ideal for most lawns.

3. Keep blades sharp: Dull mower blades stress the grass and increase disease risk.

4. Aerate twice yearly: Spring and autumn aeration improve drainage and prevent moss.

5. Overseed annually: Thick grass is the best defence against weeds and bare patches.
