WHAT IS LAWN THATCH?

Lawn thatch is a layer of un-decomposed stems, roots and other debris that accumulates near the soil surface.   When thatch becomes excessive, the lawn may root into the thatch rather than the soil. Since thatch does not hold moisture, lawns rooted into thatch will not tolerate dry weather or cold temperatures. Thatch can harbor insects and diseases,  limit root development  and restrict water infiltration. The rate at which thatch accumulates is determined by moisture, environmental conditions and the type of grass. Over application of nitrogen promotes thatch accumulations.

NOTE: Contrary to popular belief, grass clippings do not contribute to thatch accumulations. In fact, grass clippings, left on the lawn, can stimulate soil biomass and produce nutrients necessary for healthy plant growth. 

CONTROLLING LAWN THATCH
Lawn thatch digester will decompose lawn thatch, grass clippings and other organic residue. In addition, it will aid in the restoration of soil biomass, build humus and promote plant establishment.

LAWN THATCH DECOMPOSER For thatch prevention apply thatch digester once per season, preferably in early spring.
LAWN THATCH DECOMPOSER For thatch reduction apply 2 to 3 times per season depending on the degree of thatch.
NOTE:
To optimize the efficacy of thatch digester, apply when soil temperature is above 40F.
