Spreading and Levelling
The topsoil should be a loamy sand, sandy loam, clay loam, loam, silt loam, sandy clay loam or other soil suitable for the area. Check the pH levels to make sure it is suitable to your grass of choice. You can either use lime to increase or sulphur to decrease the pH level. These can be added into the topsoil before being spread on your lawn.
- Sir Walter Buffalo: 5.6 – 7 pH
- Kikuyu: 5.5 – 6.5 pH
After placing the top soil, spread it out using wheelbarrows and shovel. Then finish it off by using a rake and leveller to even it out.
Level the surface
Try to estimate where water will run when it rains and eliminate drainage problems. Make sure to allow for the height of the turf along paths. If you are installing buffalo or kikuyu, leave your soil height below the top of the path by around 40mm. This will allow the leaf of the grass to be above the path. You will also need to lightly compact the soil to prevent unevenness or sinking after installation.
