Thatch & Thatch Control
Thatch in turf is the accumulation of old leaves, clippings, stems, roots, and other organic material which has failed to decay. Thatch sheds water rather than letting it percolate into the grass root zone. It may harbour fungus and other diseases, as well as insect pests, and may make fertilizer applications ineffective.
One of the answers to the thatch problem is a vigorous raking. This is difficult to do by hand. A much easier way is to use a powered vertical mower which is self-propelled and equipped with hardened steel blades. It cuts out the thatch and thins matted growth. If desired, you can set the blades low enough to touch the soil; the scarifying action is an ideal pre-seeding treatment for bare or thin areas that need over-seeding.
