Calculations are estimates. Always check specific roll sizes with your chosen supplier as dimensions can occasionally vary.
How to Lay the Perfect Lawn
Follow these essential steps to ensure your new turf establishes quickly and thrives.
1. Preparation is Key
A beautiful lawn starts with the soil. Remove all old grass, weeds, and large stones. Dig over or rotovate the soil to a depth of at least 150mm.
If your soil is poor, use our calculator above to work out how much topsoil you need to add. Rake the area level and firm it down by walking over it using the "heel and toe" method.
2. Laying the Turf
Start laying turf along a straight edge, like a patio or fence line. Unroll carefully, ensuring the underside makes full contact with the soil.
Stagger the joints in a brickwork pattern. Never stretch the turf; instead, push the edges tightly together. Use a sharp knife or half-moon edging tool to trim the edges.
3. Watering
Water the turf immediately after laying. The water needs to soak through the turf and into the soil below.
Keep the turf constantly moist for the first two to three weeks. In hot weather, this might mean watering twice a day. Never let newly laid turf dry out and shrink.
4. Aftercare
Avoid walking on the new lawn for at least 2-3 weeks to allow the roots to establish. You can check root establishment by gently tugging a corner of the turf.
Once rooted, you can give it its first mow. Set the mower blades high and only remove the top third of the grass blades.
Pro Tip: The Planks Method
When laying turf, never walk directly on the newly prepared soil or the freshly laid turf. Instead, use wooden planks or boards to stand on and work from. This spreads your weight, preventing footprints in your perfectly levelled soil and avoiding damage to the new grass. Move the boards forward as you progress across the lawn.
