Choose a lawn renovation by looking at how much useful grass remains and what caused the damage. A few gaps can be repaired locally; a thin lawn with grass across most of it may suit overseeding. If the lawn is mostly bare or the surface needs major correction, starting again may be more practical.
Check the lawn before deciding. Grass browned by dry weather can recover when conditions improve, while repeated wear, deep shade or ground that stays wet may need attention before any repair will last. Our guide to why lawns become thin and patchy helps you look for clues.
When should you renovate?
Plan work for conditions in which existing grass can recover and new seed can establish. Spring and early autumn are common windows; the RHS recommends spring or autumn for lawn repair. Wait if the ground is frozen, saturated or very dry, and allow time to keep newly seeded areas moist.
Repair a few bare patches
Where most of the lawn is healthy, focus on the gaps. Remove dead material, prepare and level the exposed soil, and sow a mix suited to the light and use the patch receives. If people always take the same route across it, a stepping stone or change of route can reduce wear.
For the detailed sequence, see how to repair a patchy lawn.
Refresh a thin existing lawn
If useful grass remains across a wider area, overseeding can add new plants without removing the whole lawn. Mow and clear the surface first so seed can reach soil between existing plants. Choose a mixture suited to the site, use its overseeding rate and protect the area during establishment.
Some lawns also benefit from removing accumulated surface material or aerating compacted ground. Choose those jobs according to what is present, and avoid pulling out healthy grass unnecessarily. The RHS autumn-care guide explains scarifying and aeration; not every task is needed every year. Our overseeding guide takes you through sowing and aftercare.
Start again when the surface needs major work
A lawn with very little useful grass, extensive bare areas or serious unevenness may need more substantial preparation. Starting from seed involves clearing unwanted vegetation and debris, correcting the surface, allowing disturbed soil to settle, then firming and raking a seedbed before sowing.
Seeding gives you a choice of mixtures but needs time and care while the lawn establishes. Turf is another option. See how to prepare soil for grass seed if you decide to sow.
Plan for recovery
A lawn can look untidy immediately after preparation. Recovery varies with the weather, soil, seed and aftercare, so allow for a period with reduced traffic. Water new seed gently as needed and check whether any feed or treatment is suitable for newly sown grass. Our guides to watering new seed and the first mow cover the next steps.
