Come spring, your lawn may have suffered from winter weather. The grass may have thinned out overall, or bare patches may have appeared.
In extreme cases, the damage may warrant replanting a completely new lawn, but in many cases you can repair the damage and return the lawn to its lush, green state in time for the summer. This involves either repairing bare patches in the grass, or over-seeding the entire lawn. Garden centres sell special lawn seed mixtures for reseeding and repairing.
Seed the lawn
Cut around the damaged area of your lawn with a half-moon edge cutter to a depth of 20 to 25 cm. Ease a garden spade under one edge and lift the turf out.
Loosen up the soil in the patch with a garden fork. Add some compost to the hole, filling it to the level of the surrounding soil. Firm it down.
Cast seed on the lawn, following the manufacturer's recommendations as to the amount. Cover the seed with a 2.5 cm layer of compost. Firm it down gently enough to avoid compaction.

Mix grass seed with compost in the proportion recommended on the packet. Rake the mixture over the existing grass so that there is about a 2.5 cm layer covering the whole lawn.
Soak the lawn with a sprinkler for at least 30 minutes. Water every day until the new grass sprouts in about seven to 10 days.
- Keep people and pets off the reseeded lawn, or reseeded sections, for three to four weeks to allow the new grass time to establish.
- Wait until the last frosts have passed before reseeding your lawn.
