When do you de-thatch?
Spring or Fall
Thatch control is best performed in the spring or fall of the year, with
fall being the best time of year for lawn work. The "ideal" period in the
Pittsburgh area is August 20th through October 20th. The following three
steps will help control thatch depth in the northeastern US: core aeration,
dethatching, and liming (or other pH control) as needed.
helps prevent Thatch Build-up
Aeration of your
lawn once (fall) or twice (spring & fall) a year will help prevent
thatch buildup, improve the penetration of fertilizer and lime into the
root zone, and allow the soil to "breathe". We use machines that pull a soil plug
or "core." The cores are left on the lawn surface to breakdown and
usually disappear within three weeks.
aeration should be performed once or twice a year since it will help
prevent thatch build-up which can result in later renovation expenses
When thatch approaches or
exceeds the safe "threshold" of 1/2-inch thick, it becomes necessary to employ
removal techniques. We use a flail-type "thatching" machine to remove a
portion of the thatch layer. For lawns with extremely thick thatch
(1-inch or more) we recommend stripping the thatch layer and starting a
new lawn from bare soil.
The third step in thatch
control is making a light application of ground limestone. Even though your soil
pH may be in the correct range, the thatch layer can be very acidic, reducing its tendency
breakdown. We use pelletized lime for our applications since it makes less mess and speeds
our application. We recommend a soil test for
anyone serious about improving their lawn's long term quality. Soil test
results are usually back within 3 to 4 weeks.

you renovate a lawn?
Spring or Fall
Lawn renovation is best performed in the spring or fall of the year, with fall being the
best time of year for lawn seeding. The "ideal" period near
Pittsburgh, PA is August 20
through October 20, the earlier in that 60-day period the better. Good
irrigation of newly seeded areas will greatly improve success.
In addition to the
procedures mentioned above in "Thatch Control", we also overseed
your lawn with
improved varieties of grass seed and apply a "starter" fertilizer. Depending on
your individual needs, we may also fill-in depressions in the lawn with
soil, and apply a mulch to
help keep the grass seed moist.
When thatch exceeds
1/2" thick, we recommend stripping the lawn down to bare soil with
sod-cutter and starting from "scratch" (bare soil).
This speeds the renovation process and
has the added benefit of seeding the lawn entirely with improved varieties of
& weedy grasses
On many occasions, an
is infested with tenacious weedy grasses that can only be removed with chemical controls
(herbicides). In these instances, we begin the "Total Renovation" process with an
herbicide application to remove the majority of undesirable grasses and weeds.
