In many new housing developments, the developer supplies the home with lawn to give the homeowner something green to get him/her started. In many cases, the lawn may look green and healthy for a few seasons, but then gradually starts deteriorating, leaving unsightly bare patches. Very often, no matter how much lawn dressing and fertiliser is applied, the lawn just doesn’t recover completely.
If there is limited traffic on the lawn, it is likely that the problem lies in the condition of the soil. To investigate further, you’ll need to dig to find out what is happening underneath your lawn. In the majority of cases, we find that the lawn was laid directly on builder’s rubble or over an area where the builders did their cement mixing. Here are 2 examples:
Preparing your soil
How to prepare your soil for lawn:
- Dig and loosen the soil to a depth of 20 – 30cm
- Remove any stones, rocks, debris or concrete that can impede the growth of your lawn
- Apply compost, about 1 x 60dm bag per 4 square meters, and lightly work it in with a fork
- Apply Superphosphate (and/or bonemeal) to encourage root development, at a rate of 50g per square metre
- Dig over the area again and rake it level
- Check the levels and ensure that runoff and drainage have been considered
- Lightly roll or stamp the area to settle any air pockets and to prevent uneven surfaces
- Rake the soil lightly again to get a fine finish
Once you have completed these tasks you can plant your lawn sods, or lawn plugs. If you are using sods, give the lawn one last roll with the roller once you have planted it, again to remove any air pockets and to settle it into your ground.
