Organic lawn care doesn’t mean you sit back
and watch as weeds infiltrate your lawn until dandelion lint covers
your sidewalk. Nor does it mean that you need to be out on hands and
knees from sunrise until sunset, hand-pulling crabgrass and invasive
weeds in order to have the lush green carpet of your neighbors’
chemically treated lawns. What organic lawn care does mean is that
with a good lawn care plan and a minimum of work, you can have an
attractive addition to your landscape that is safe for both your
family and the environment.
In organic lawn care, as in all organic gardening, the foundation
for building a great lawn is your soil. The first step in planning a
lawn is to find out what kind of dirt is under your grass. A soil
test, from your county extension agent or other lawn care
professional, tells you whether it’s sand or clay based, nutrient
rich or nitrogen poor, acid or alkaline. From there, you can decide
how to improve (amend) it and choose the seed that will give you
more green for your colorful US dollar.
A basic rule of thumb in organic lawn care is that it’s more
important to feed the soil than to fertilize the grass. Nutrient
rich soil holds moisture, entices beneficial insects, and maintains
a healthy environment for microorganisms that fight disease, deters
pests and parasites, and generally help keep your lawn growing and
green. Six to ten inches of good top soil is worth its weight in
green for your lawn!
A mulching mower solves two problems in organic lawn care with just
a few swipes of its blades. First of all, when mowing, always keep a
high clip (2 ½ to 3 inches) unless it’s your final mowing in the
fall. Short grass clippings and especially fine mulch from a
mulching mower will fall in between the cut blades of grass and
reach the soil where they quickly decay, adding nitrogen and other
nutrients to your soil. Because grass is very efficient in its use
of nitrogen, composting your lawn with grass clippings can radically
cut down on your fertilization needs. Grass clippings alone can
contribute up to two pounds of the two to six pounds per 1000 square
feet that your lawn needs to stay healthy.
During dry seasons, an organic lawn care basic is to water your lawn
infrequently but deeply. Deep watering forces grass roots down while
over-watering allows them to remain near the top. Deeply rooted
lawns better compete with invasive weeds.
In addition to helping your lawn retain moisture, annual lawn
aeration is one organic lawn care method of giving easy growing room
to roots and provides circulation for the colonies of critters that
tend your soil. The best time to aerate your lawn is in the spring.
Not only will spring aeration break up the compaction of frost and
snow accumulated during winter, spring rains also help aeration
clumps decay quickly, further enriching your topsoil.
