Healthy
grass out-competes most weeds and diseases and by adopting good turf
maintenance practices, your lawn will look good and be free of most
obnoxious weeds.
How do
I mow my lawn?
Seems
like a simple question, right? Well most people seem to think so until
they find out the proper way to mow. The problem is most people seem to
mow in the same pattern and direction each time. By doing so, they
create streaks and striped lines that grow back irregularly and look
rather unsightly. To keep your lawn as healthy as possible, it is
important that your lawn is not trampled or continuously matted to the
point were it is not allowed to grow properly. To help avoid this
problem, it is best to change your mowing directions each time you mow.
You should either cut cross-diagonally or in the opposite direction each
time you mow.
Should
I mulch my lawn?
In
general, mulching your lawn is a good idea because it helps provide the
soil with increased ground cover to hold moisture, and acts as a
fertilizer. Clippings can contain up to 80% water and 5% nitrogen that
can continuously fertilize your lawn! Additionally, mulching can reduce
the amount of fertilizer you need to apply to your lawn. Mulching also
reduces the headache of bagging your lawn and disposing of cut
clippings. Again, the common side effect to mulching is development of
thatch in your lawn. As a rule of thumb, mulching is recommended during
times of seasonal droughts, heat waves, and after fertilization and lawn
development. Conversely, it is recommended that you try to rake and bag your
clippings occasionally, especially when you witness either a build-up of
clippings on the lawn surface or an excess development of thatch in the
lawn.
Fertilizing
The Lawn:
Fertilizers are
commonly labelled with N-P-K ratios (N=nitrogen,
P=phosphorus, K=potassium). Nitrogen makes lawns green, phosphorus promotes good roots, potassium
is a disease fighter. Other trace elements are needed for a healthy
lawn. Calcium promotes root hair growth, magnesium is a big part of
chlorophyll, sulfur helps seeds form, boron improves the yield, copper
makes enzymes work harder, manganese stimulates germination, molybdenum
makes nitrogen enzymes work harder, and zinc is needed for chlorophyll
and growth.
What kind of fertilizer should I use?
There are two
basic categories of nitrogen fertilizer -- soluble and slow release.
Soluble fertilizers are available quickly to plants (even at low
temperatures), stimulate rapid growth and are depleted quickly. To keep
your lawn healthy, use fertilizer with slow release nitrogen. To
maintain uniform growth over a long period of time and to prevent
possible burning, you'll need to make frequent, light applications of
the materials. Slow release nitrogen sources depend on soil bacteria or
moisture to gradually decompose the materials and transform the
compounds into usable forms of nitrogen. Consequently, they release
nitrogen to the grass over a longer period of time.
How often should I water my lawn?
Water
(or rainfall) at a rate of 1" per week about every 3 or 4 days
during the growing season. A little more often if the temperature is
very high. Water deeply to wet the top 3 to 5 inches of the soil to
encourage deeper root growth. Avoid daily light watering as this will
promote shallow root growth and make the lawn more prone to drought
conditions. If you are starting a new lawn, frequent watering to keep
the soil moist is essential. An automatic lawn sprinkler system will
help you water properly and easily without wasting water.
