Your lawn takes nutrients out of the soil that it is bedded
in and uses these nutrients to aid its growth. If your soil
lacks these nutrients your lawn will ultimately suffer.
So while fertilizing makes your lawn greener it also provides
a top of any nutrients that your soil is lacking helping
grass to grow. When the nutrients are available, the lawn
develops healthier roots which invariably grow deeper allowing
the lawn to draw upon water and nutrients in the soil. Furthermore,
deep roots reduce thatch and browning. Finally, fertilizer
contains nutrients that grass needs to resist disease and
drought.
Fertilizers also offer the additional benefit of including
chemicals to inhibit or kill weeds. The three primary nutrients
in a fertilizer are Nitrogen, Phosphorous and Potassium.
Each element has its own affect upon grass. Nitrogen stimulates
grass growth and greening. Phosphorous stimulates the development
of roots and seedlings. Potassium promotes disease and drought
resistance.
As the weather changes, so too does your lawn have changing
needs. In the heat of the summer, your lawn needs water
and little else. In order to survive the cold weather, your
lawn needs to have healthy roots and so a fertilizer to
promote root growth should be applied before the cold weather
sets in. At other times of year your lawn needs nutrients
to enable growth and greening. Weeds also have their own
growing seasons so you should fertilize at the beginning
of the various weed growth seasons.
Where you live, the type of grass you have, the condition
of your soil and the weather all affect your choice of fertilizer
and when it should be applied. You also have a choice of
organic fertilizer, liquid fertilizer, which is sprayed
on, or time released granules which are distributed with
a spreader. All of these factors result in the many choices
of fertilizer. And of course you can always purchase your
fertilizer via a wholesaler online, meaning that the more
you buy the cheaper the deal.
