Remove any debris including leaves, roots, twigs, rocks and weeds from the soil area. Level and shape the ground when the soil is dry using a straight board. Allow 30mm below paths, driveways and similar areas for the grass to be laid on top and remain level with the surrounding surface. Soil water repellency may be overcome with the use of a wetting agent, such as Richgro's Ezi-Wet soil wetter.
If reticulation is to be installed, now is the stage to install the system. The sprinkler heads should be positioned 20mm above the surface of the soil allowing for the height of the lawn. Reticulation is strongly recommended for establishing any lawn, particularly through summer.
