Scarifying is the most important task next to regular mowing, and cab help you to achieve the best possible lawn. Scarifying improves the grass and soil condition of your lawn by removing dead leaves and thatch build up. Dead grass, roots and other material, can choke a lawn robbing the soil of air, water and essential nutrients. The best time to scarify is in autumn, before applying fertiliser, or mid-spring as the grass starts to grow. Treat any moss problem before scarifying. After scarifying your lawn will look ragged but will recover quickly, as new grass fills in any bold patches. If extensive patches occur, re-seed where necessary.
