If you have hard ground or need to incorporate soil amendments like bentonite clay or organic matter into your soil prior to laying it is a good idea to rotovate the ground. Grass roots prefer and will grow better in softer soil. Once you have prepared your site and levelled the ground should be soft but firm enough to leave only a shallow footprint.

If you have existing grass or weeds, this vegetative material needs to be removed prior to rotovating your soil.
