Highlights Thatch Core Aeration Endophyte Grasses Overseeding Mowing Watering pH Level

Thatch is the excessive build-up of dead roots and grass. Thatch build-up is one of the worst problems for a lawn. It harbors insects, fungus and disease. It also prevents nutrients from reaching the root zone, effectively starving the plant.

Thatch is created by the use of quick release nitrogen and the use of synthetic insecticides. Synthetic insecticides are not selective and will kill off many beneficials, including the bacteria which decomposes thatch. Quick release fertilizer which overfeeds grass, as well as the conditions listed above, causes the accumulation of thatch.

Thatch can be removed mechanically with a "power rake" which cuts out the thatch. The remaining debris should then be removed manually. Our programs return much needed bacteria to the soil so that the thatch problem is eliminated.
