The full year, in plain English. What kit to buy, then the order to do it in: scarify, aerate, feed, level with a lute, overseed and water. No jargon.
A green lawn is not luck, it is a routine. Do these jobs in roughly this order and the grass stays thick and green year after year. Most of the year is just mowing, feeding and watering, the heavy lifting happens once, in autumn.
New to it? Read top to bottom. Already mowing and just want the deep-green upgrade? Skip to the autumn cycle: scarify, aerate, top dress with a lute, overseed and feed.
You do not need everything at once. The first four lines below cover the autumn cycle that makes the biggest difference. Prices are rough UK 2026 ballparks for home-garden kit.
Pulls out dead thatch and moss. A hand rake is fine for small lawns; a powered scarifier saves your back on anything over ~150m².
Opens up compacted soil so air, water and feed reach the roots. A sturdy fork does the job; a hollow-tine tool pulls cleaner cores.
A flat, toothless frame that drags top dressing level and works it into hollows. The tool that turns a bumpy lawn into a flat one.
Spreads feed and seed evenly so you avoid stripes of burnt grass and bald patches. Far more even than scattering by hand.
The right cut is half the battle. Match the mower to your lawn size and whether you want stripes. We compare 176 of them.

For overseeding thin and bare patches. Match the mix to your sun/shade and how much wear the lawn takes (family vs ornamental).
A thin layer worked in with the lute fills holes, smooths bumps and improves the soil over time. Buy a ready-mixed lawn dressing.

Spring feed (high nitrogen) drives green growth; autumn feed (high potassium, low nitrogen) hardens roots for winter. Never swap them round.
A deep soak twice a week beats a daily sprinkle, because it grows deeper roots. A water butt keeps it cheap and through hosepipe bans.

A combined "weed, feed & moss-killer" in spring handles all three at once. Rake out the blackened moss a couple of weeks after.

Good mowing is the foundation. Never cut more than one third of the height in a single pass, keep the blades sharp so they slice instead of tearing (torn tips go brown), and raise the cut in summer so longer grass holds moisture. Mow when the grass is dry.
Thatch is the dead, matted layer of old grass and moss sitting at soil level. Too much of it blocks water, air and feed. Rake hard with a spring-tine rake, or use a powered scarifier, until you can see soil between the grass. It looks scruffy straight after, that is normal, it bounces back in a few weeks. Bin all the debris.
Compacted soil starves the roots. Push a garden fork about 10cm deep and rock it gently, repeating every 10 to 15cm across the whole lawn. On bigger lawns a hollow-tine aerator pulls out small soil plugs, leave them to dry then rake them up. Do not skip this on a lawn that gets walked on a lot.
Spread a thin layer of top dressing (a sand, soil and compost mix) over the lawn, then drag it level with the lute, working it down into the aeration holes and any dips. Aim for a flat surface with the grass tips still poking through, do not bury the grass. This fills holes, smooths bumps and steadily improves the soil.
Scatter fresh grass seed over the worked surface, concentrating on thin and bare areas. Choose a mix that matches your sun, shade and wear. Lightly rake it in so it sits in contact with the soil, water gently, and keep off it until the new grass establishes (a few weeks).
This is what gives the deep green colour. Spring (Mar to May): high-nitrogen feed to push growth. Summer: a lighter balanced feed. Autumn (Sept to Oct): an autumn feed (low nitrogen, high potassium) to strengthen roots for winter. Never use spring feed in autumn, it forces soft growth that frost kills. Spread it evenly and water it in.
A good soak twice a week beats a light daily sprinkle, because it encourages deep roots. Water early morning or evening to lose less to evaporation. If the lawn goes straw-coloured in a drought, do not panic, it almost always recovers when the rain returns.
Spot-treat weeds and moss as they show up, which is gentler than blanket treatment. A combined weed, feed and moss-killer in spring handles all three at once. Rake out the dead, blackened moss a couple of weeks after treating it.
Get autumn right and the rest of the year looks after itself.
| Season | Months | What to do |
|---|---|---|
| Spring | Mar – May | Light scarify, overseed bare patches, spring feed, start mowing regularly, treat weeds & moss. |
| Summer | Jun – Aug | Mow high, water deeply, light summer feed, spot-treat weeds. |
| Autumn | Sep – Oct | The big one: scarify, aerate, top dress & lute, overseed, autumn feed. |
| Winter | Nov – Feb | Stay off frosty grass, keep it clear of leaves, mower away for service. |
