How to get a lush, verdant hue from the lawn that you
tend so lovingly from year to year; now that is a hotly contested
subject and one that needs some objective comments.
Is it about
the choice of grass originally sown or laid?; is it about climatic
factors?; is it about the condition of your soil?; is it about the the
type of soil?; is it about turf being better than seeding?; is it about
scarifying and general care and maintenance?; is it about water
application?;or is it about nutrients? You are about to get some
answers.
Always bear in mind that there are two very general
choices for grass, one strain that grows well in the Northern
Hemisphere and that other that fairs well south of the Equator. Getting
this wrong is disastrous, so ensure you have the correct variety. They
are categorized as cool season grasses (for northern climes) and warm
season grasses (for antipodeans).
For the north, Kentucky
Bluegrass is a good choice - make sure it is a recent mix of varieties
- because it tends to maintain its form without too much feeding and
even in an extended rain free period. The variations of Fescue are also
a preferred option as they need vary little care to maintain their
lushness. So, mixture is critical; make sure you find the right mix
from reputable suppliers.
The natural soil substructure need not
be a problem with lawns; topsoil is normally all that is necessary for
a successfully green lawn, although do make sure that the subsoil is
sound and not likely to sink.
If you are starting from scratch,
ensure you add enough sand to the topsoil to aid proper drainage;
waterlogged areas will not give you the green lawn you desire but quite
the reverse. Make sure you add in fertilizer which is probably the
single most important factor for obtaining a greener lawn. We will come
to that shortly. Bulk produced fertilizers tend to produce better
results, but if you wish to go organic you can use materials such as
peat moss, leaf mold and pine bark.
The condition of the soil should also be assessed with regard to adding extra lime where necessary.
Scarifying
your lawn will obviously help because the roots thrive on an oxygen
supply which will also help to make the grass leaves greener in the
long term. Removing moss and other undesirables with a sturdy grass
rake will also help immensely by removing competition for the soils
nutrients.
It is nutrients which will ultimately give your lawn
the greener look that you so crave. Organic nutrients are fine and have
their place in the garden but they are time consuming to produce, hard
to apply quickly and efficiently and do not contain the same intensity
and concentration of proprietary brands.
To assess different
fertilizer and nutrient products, first look at what they are designed
to do. You want a richer, greener lawn so make sure that the product is
geared up to achieve the results you want.
A broad rule of thumb
to begin with is around ten to fifteen kilos of a high grade
fertilizer, such as N5-P10-K15, N6-P12-K12, N5-P10-K10, or N7-P14-K21
for each 1000 square feet of lawn. When a soluble form of nitrogen is
employed, do not utilize in excess 500 grams of nitrogen per 1000
square feet.
If you follow the few basic rules outlined above, it
is then all about choosing the best product available for making your
lawn greener. Shop around and see what works for you.
