Define the area to be repaired. If patching with turf rolls or slabs, cut the area to shape with clean, square edges using a spade. If using seed to repair, then define the required shape.
Remove any old grass and deeply aerate with a garden fork. Make sure that all the old grass is removed as well as any material like twigs, roots or rocks. Drive the fork in at least 5cm deep at around 5cm spacings across the entire area. This improves aeration and is vital if the soil was compacted.
Add turf soil mix and starter fertiliser and level. For small areas, bagged turf mix or turf underlay soil is the quick and easy option. Whether using rolls or seed, add lawn starter fertiliser to speed up establishment. Check the seed you are using as some will have a starter blended in. If you have clay soil, spread gypsum too.
Use the flat back of your landscape rake to bring to level. Here’s where there is a difference between rolls and seed. For rolls or slabs, the soil should be levelled to around 10mm below the surrounding soil to allow for the root layer of the rolls. When laying seed, the soil should be left slightly mounded (around 10mm above) to allow for natural settling.
Position turf and trim to fit. When laying the rolls or slabs it’s best to start along an existing straight edge to allow for a neater finish. Once rolls are in and trimmed, use a little lawn mix to fill any gaps along the edges and smooth out any transition between old and new.
If using seed, water the area lightly. This helps the seed “stick” to the soil. Distribute the seed evenly, allowing a little to scatter into surrounding grass to create a blended area.
Water well, first with water and then with a seaweed solution. Don’t use a fertiliser-fortified blend as you’ve already fed with your starter fertiliser. If using seed, take care to water gently to avoid any seed being washed away.
Turf rolls can be walked on immediately, but it’s best to keep people off for around a week. Keep moist but not wet until the grass starts to take hold to the soil below.
A seed lawn will require you to keep all foot traffic off for at least a few weeks, generally until the first mow. See the pack for more details. Seed will need to be kept reliably moist until well established. This may mean watering twice a day in warmer weather.
