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

thatch digester once per season, preferably in

apply 2 to 3 times per season depending on the
degree of thatch.
