Raking your lawn to remove moss and a build up of dead grass and debris (thatch) prevents the lawn feeling too soft and spongy when walked on. Raking also allows air to the grass and creates healthier growing conditions. When moss growth is very thick, it is advisable to kill the moss a few weeks prior to raking with a moss killer which can easily be applied in granular form. The Flymo Lawnrake Compact 340 makes light work of lawn raking and moss removal.
Raking is normally done in spring or autumn, but a light raking in early summer on a high setting when the grass is green and growing will greatly improve the condition of your lawn.
