4. Water Deeply But Not Too
Often
Watering properly will help your lawn grow deep roots that make
it stronger and less vulnerable to drought. Most lawns are watered
too often but with too little water. It's best to water only
when the lawn really needs it, and then to water slowly and deeply.
This trains the grass roots down. Frequent shallow watering trains
the roots to stay near the surface, making the lawn less able
to find moisture during dry periods.
Every lawn's watering needs are unique: they depend on local
rainfall, the grass and soil type, and the general health of
the lawn. But even in very dry areas, no established home lawn
should require daily watering.
Try to water your lawn in a way that imitates a slow, soaking
rain, by using trickle irrigation, soaker hoses, or other water-conserving
methods. It's also best to water in the early morning, especially
during hot summer months, to reduce evaporation. Apply about
an inch of water--enough that it soaks 6-8 inches into the soil.
Then let the lawn dry out thoroughly before watering it again.
The best rule is to water only when the lawn begins to wilt from
dryness--when the color dulls and footprints stay compressed
for more than a few seconds.
5. Correct Thatch Build-Up
All grass forms a layer of dead plant material, known as thatch,
between the grass blades and the soil. When thatch gets too thick--deeper
than one-half inch--it prevents water and nutrients from penetrating
to the soil and grass roots. Some grasses tend to form a thick
layer of thatch. Overuse of fertilizer can also create a heavy
layer of thatch. |

You can reduce thatch by raking
the lawn or using a machine that slices through the thatch layer
to break it up. Sprinkling a thin layer of topsoil or compost
over the lawn will also help.
In a healthy lawn, microorganisms and earthworms help keep the
thatch layer in balance by decomposing it and releasing the nutrients
into the soil.
6. Set Realistic Goals
Setting realistic goals will allow you to conduct an environmentally
sensible lawn care program. It's probably not necessary to aim
for putting-green perfection. Did you know that a lawn with 15
percent weeds can look practically weed-free to the average observer?
Even a healthy lawn is likely to have some weeds or insect pests.
But it will also have beneficial insects and other organisms
that help keep pests under control.
Also realize that grass just can't grow well in certain spots.
Why fight a losing battle with your lawn, when you have other
options? At the base of a tree, for example, you might have better
luck with wood chips or shade-loving ornamental plants like ivy,
periwinkle, or pachysandra. If your climate is very dry, consider
converting some of your lawn to dry-garden landscaping. It could
save time, money, and water resources.
What Is IPM?
Integrated Pest Management is essentially common-sense pest control.
IPM is not a new concept; some forms of it have been practiced
for centuries.
IPM involves the carefully managed use of three different pest
control tactics--biological, cultural, and chemical--to get the
best long-term results with the least disruption of the environment.
Biological control means using natural enemies of the pest, like
lady bugs to control aphids. Cultural or horticultural control
involves the use of gardening methods, like mowing high to shade
out weeds. Chemical control involves the judicious use of pesticides.
IPM is a highly effective approach that minimizes the use of
pesticides and maximizes the use of natural processes. Lawn care
professionals who use IPM should have a sophisticated understanding
of the ecosystem of your turf and the available pest control
tactics. Home gardeners can also practice IPM by following the
steps outlined in this brochure.
Tips For Using Pesticides
Sometimes, even with good lawn care practices, weather conditions
or other factors can cause pest problems to develop. Pesticides
can help control many lawn pests. But pesticides have risks as
well as benefits, and it's important to use them properly.
The chemicals we call pesticides include insecticides, herbicides,
and fungicides. These products are designed to kill or control
pest insects, weeds, and fungal diseases. Pesticides can be very
effective. But don't be tempted to rely solely on pesticides
as a quick-fix solution to any lawn problem.
Serious, ongoing pest problems are often a sign that your lawn
is not getting everything it needs. In other words, the pests
may be a symptom of an underlying problem. You need to correct
the underlying problem to reduce the chance that the pest will
reappear.
All pesticides are toxic to some degree. This means they can
pose some risk to you, to your children and pets, and to any
wildlife that venture onto your lawn--especially if these chemicals
are overused or carelessly applied. Pesticides can also kill
earthworms and other beneficial organisms, disrupting the ecological
balance of your lawn.
Store pesticides out of children's reach in a locked cabinet
or garden shed.
When Spraying, Protect your skin, your eyes, your lungs
Wash this clothing separately before using it again.
Before Using Any Pesticide, Be Sure To Review These Basic Rules
1. Take safety precautions. Never assume a pesticide is
harmless. Read the entire label and follow its instructions.
Use only the amount directed, at the time and under the conditions
specified, and for the purpose listed.
Be sure to wear any protective clothing--like gloves, long sleeves,
and long pants--indicated on the label. Wash this clothing separately
before using it again.
Keep children and pets away from pesticides, and make sure no
one goes on a treated lawn for at least the time prescribed by
the pesticide label.
Remember to follow any state or local requirements for posting
your treated lawn or notifying your neighbors that a pesticide
has been applied.
Store and dispose of pesticides properly, according to the label
directions and any state and local regulations.
2. Use pesticides to minimize pests, not eradicate them.
The latter is often impossible and unnecessary.
3. Be sure you have accurately identified the pest so
you can choose the best pesticide for the job and use it most
effectively. Obtain professional advice from your county extension
agent or a local expert.
4. Spot treat whenever possible. In most cases, it isn't
necessary to treat the whole lawn with pesticides if the problem
is confined to certain areas. Spraying more than necessary is
wasteful and can be environmentally damaging.
