Thatch is a build-up of organic matter, which can include dead grass leaves, stems, stolons, rhizomes and overcrowded grass roots and lateral weed growth. Thatch can stifle the growth and health of grass. Power raking of lawns is a mechanical process whereby the surface and subsurface of the lawn is rigorously abraded by metal tines. Removing the thatch can be a benefit by:
- encouraging grass to thicken up
- making grass stronger and less susceptible to disease.
- increasing the levels of water, air and nutrients that can get through to the root zone.
- helping grass to thicken up over time
