UK Lawn Care Calendar 2026: Month-by-Month Mowing Guide
British lawns follow a reliable annual rhythm, but the climate varies enough between the south-west and Scotland that following a rigid schedule by date alone leads to mistakes. This calendar sets out what to do each month, tied to grass behaviour rather than just the date, so the approach holds whether you garden in Cornwall or Aberdeenshire.
How this calendar was compiled
We don't run a test lab and we don't pretend to. Our recommendations are built from published manufacturer specifications, verified owner reviews on Amazon UK and retailer sites, and UK pricing data, cross-checked so the numbers on this page match the numbers you'll find on the box. Where a figure is the maker's claim rather than an independent measurement, we say so.
Rankings are based on cut quality, battery and runtime for the garden size in question, weight, build, and value at UK prices. We update picks when models are discontinued or superseded. We earn affiliate commission on some links, but it never decides the order of a list. More on our method.
January and February: rest and preparation
Grass growth is negligible in most of the UK during these months. Soil temperatures are typically below the 5-6 degrees C threshold at which growth resumes, so mowing is not needed and should be avoided on frozen or waterlogged ground.
What to do instead: clear fallen leaves, twigs, and debris from the lawn surface. Lying debris blocks light and encourages moss and disease. Keep foot traffic to a minimum on frozen grass, as the ice crystals inside the blades shatter under pressure, leaving visible brown tracks that persist for weeks.
For cordless mower owners, January is the best time to check battery health. Manufacturer guidance consistently recommends storing lithium-ion batteries at 40-60 percent charge in a frost-free location. Read the full guidance in the battery care guide.
March: the first cut of the year
As daytime temperatures climb above 6-8 degrees C, grass begins growing again. Owner reviews and horticultural sources consistently report that the safest first cut of the season is a light trim only: set the blade to its highest setting (typically 40-50 mm) and remove no more than a third of the blade height.
Inspect the mower before the first cut. Check the blade for chips or blunting over winter. A dull blade tears grass tips rather than slicing cleanly, which leaves brown, frayed ends. If in doubt, follow the steps in the blade sharpening guide before the season begins.
Check the wheels, drive belt (on self-propelled models), and grass box for any winter deterioration. For battery mowers, do a full charge cycle before the first use to condition the cells.
April: lowering the blade and increasing frequency
Growth accelerates through April. The lawn can typically handle cuts every ten to fourteen days early in the month. Move to weekly towards the end of April as growth picks up. Lower the blade by one setting each fortnight rather than dropping straight to summer height in one go.
April is also when mulching becomes worthwhile. Short spring clippings break down quickly on the surface, returning nitrogen to the soil without smothering the lawn. If your mower has a mulching plug, this is a good month to start using it. See the mulching guide for how to get clean results rather than clumps.
Apply a pre-season lawn feed in April, typically a high-nitrogen spring formula. Time it after the second cut of the season, once the grass is actively growing and can take up nutrients.
May: weekly mowing and the first feed
By May, most UK lawns need cutting every seven days. Growth is vigorous and the one-third rule becomes critical: never remove more than a third of the blade height in a single pass, or the grass diverts energy from the roots to recover leaf area, weakening the sward over time.
Rainfall is variable in May. Avoid cutting wet grass where possible. Wet blades flatten rather than stand up to the cutter, which leads to tearing, clumping, and an uneven finish. If the grass is very long after rain and you cannot wait for it to dry, raise the blade height and use side discharge rather than the grass box. Full details in the mowing wet grass guide.
Hold off on a second feed until June if you applied in April. Over-feeding in spring encourages soft, disease-prone growth.
June: peak growing season
June is the most demanding month for lawn maintenance. Growth peaks. A weekly cut at the correct height keeps the lawn dense and weed-resistant. Most UK lawns perform best at a cut height of 25-40 mm in summer: low enough to look tidy, high enough to retain moisture and shade out weed seeds.
Stick to the one-third rule strictly in June. If you have missed a cut and the lawn has grown long, do not drop back to the correct height in one pass. Drop one setting per cut over two or three sessions.
Mulching clippings in June reduces watering needs by helping the soil retain moisture, and feeds the lawn with each cut. The clippings are short enough to disappear quickly. Avoid mulching if the lawn is showing signs of fungal disease, as infected material can spread spores across the surface.
July: managing drought stress
Hot, dry spells in July put lawns under heat and moisture stress. Manufacturer and horticultural guidance is consistent on this: raise the blade height during dry periods. A longer leaf blade shades the soil, reduces evaporation, and keeps the root zone cooler. Cutting too short in drought causes the grass to brown quickly and recover slowly.
Reduce mowing frequency during dry spells. If growth has slowed noticeably, cutting weekly removes a large proportion of the limited leaf area and stresses the plant further. Cut every ten to fourteen days in dry periods, or when the grass genuinely needs it rather than by the calendar.
Owner reviews of cordless mowers consistently note that battery runtime is less affected in summer than expected, because dry, shorter grass cuts more easily than long, wet spring growth.
August: bare patches and the return of rain
Rain typically returns in August after a dry July, and growth resumes quickly. Continue the raised blade approach until a sustained wet period confirms the drought is broken rather than just a single day of relief.
Late August is a good window for overseeding bare or thin patches, particularly if there has been rain. Grass seed needs consistent moisture to germinate, and the soil is still warm enough to support rapid establishment before autumn. Scatter seed onto scarified or raked bare patches, press it in gently, and keep off the area for three to four weeks.
Avoid feeding in August. Late summer nitrogen encourages soft growth that is vulnerable to the fungal diseases that arrive with autumn damp.
September: autumn recovery
Lower the blade back to summer height gradually in September, aerate compacted areas, and apply an autumn lawn feed. Temperatures drop, rain returns, and the grass enters a recovery phase before dormancy: three tasks done now save significant work in spring.
Aeration: if the lawn suffers from compaction (water lying on the surface rather than draining, or a hard, bouncy feel underfoot) September is the best time to address it. Solid-tine or hollow-tine aeration opens channels in the soil for air and water. Apply a top-dressing of sharp sand after hollow-tining to keep the channels open.
Autumn feed: use a low-nitrogen, high-potassium formula in September. This hardens the grass for winter rather than pushing soft leafy growth. Do not apply a spring formula now. It produces lush growth that disease and frost will damage.
Scarifying: if you have a heavy thatch layer (the matted layer of dead material between the grass and the soil surface), September is the best time to remove it. Scarify, then overseed bare patches immediately afterwards so they establish before the cold sets in.
October: final cut and mower service
Growth slows significantly in October as soil temperatures drop. The last meaningful cut of the season typically falls between mid-October and early November, depending on location. Set the blade slightly higher than summer height for this final cut: going into winter at around 35-40 mm leaves the grass better placed to handle frost.
After the last cut, clean the mower thoroughly. Scrape clippings from the underside of the deck, clean the grass box, wipe down the housing, and check the blade for any damage before storage. A blade left caked with clippings over winter will be harder to clean in spring and more likely to rust.
Battery storage: remove the battery from the mower, charge it to 40-60 percent, and store it in a frost-free location. Do not leave it on charge all winter. Most major battery brands, including EGO, Greenworks, and Ryobi, publish the same guidance in their user manuals.
November and December: lawn resting
The lawn is dormant or near-dormant through November and December in most of the UK. No mowing is needed, and any mowing on frozen or waterlogged ground causes more harm than the grass length justifies.
The main task for these months is keeping foot traffic off the lawn, particularly on frosty mornings. Frozen grass blades snap underfoot, leaving brown tracks that are visible for weeks after the frost clears. Set out stepping stones or a temporary path if you need to cross the lawn regularly.
Keep the lawn clear of leaves. A dense covering of wet leaves through winter blocks light and air, encourages moss, and creates the damp conditions that fungal disease needs to establish. One clear per fortnight through November and December is typically enough to prevent problems.
The mower should be stored clean, dry, and with the battery removed. If you have a petrol mower, drain the fuel or add a fuel stabiliser before winter storage to prevent gumming in the carburettor.
