Guide to a Healthy Lawn
Caring for Your Lawn in an Environmentally Friendly Way
Picture a healthy green lawn: perfect for lounging, great
for ball games and cookouts, a real asset to your home. But did you know that
your lawn - and how you take care of it - could also help the environment?
Healthy grass provides feeding ground for birds, which find it a rich source of
insects, worms, and other food. Thick grass prevents soil erosion, filters
contaminants from rainwater, and absorbs many types of airborne pollutants,
like dust and soot. Grass is also highly efficient at converting carbon dioxide
to oxygen, a process that helps clean the air.
Caring for your lawn properly can both enhance its appearance and contribute to
its environmental benefits. You don't have to be an expert to grow a healthy
lawn. Just keep in mind that the secret is to work with nature. This means
creating conditions for grass to thrive and resist damage from weeds, disease,
and insect pests. It means setting realistic goals for your lawn, whether you
or a professional lawn care service will be doing the work. And if you choose
to use pesticides, it means using them with care so as to get the most benefit
and reduce any risks. Caring for your lawn in an environmentally sensible way
can have a bigger impact than you might think. Your lawn is only a small piece
of land, but all the lawns across the country cover a lot of ground. That means
you and your lawn care activities, along with everyone else's, can make a
difference to the environment, and that's why taking care of the environment
begins in our own backyards.
Working with Nature: A Preventive
Health Care Program for Your Lawn
To start, think about lawn care as a preventive health care program, like one
you would use to keep up your own health. The idea is to prevent problems from
occurring so you don't have to treat them. As they say, an ounce of prevention
is worth a pound of cure. A healthy lawn can compete with most weeds, survive
most insect attacks, and fend off most diseases - before these problems ever
get the upper hand.
Your lawn care program should be tailored to local conditions - the amount of
rainfall you get, for example, and the type of soil you have. No matter where
you live though, you can use the program outlined in this article as a general
guide to growing a healthy lawn.
A preventive health care program for your lawn should have the following steps:
Develop healthy soil
Choose a grass type that thrives in your climate
Mow high, often, and with sharp blades
Water deeply but not too often
Correct thatch build-up
Set realistic goals
grass varieties and mixtures come out on the market every year. Ask your county
extension agent for recommendations.
1. Develop Healthy Soil
Good soil is the foundation of a healthy lawn. To grow well, your lawn needs
soil with good texture, some key nutrients, and the right pH, or
Start by checking the texture of your soil to see whether it's heavy with clay,
light and sandy, or somewhere in between. Lawns grow best in soil with
intermediate or "loamy" soils that have a mix of clay, silt, and sand.
Whatever soil type you have, you can probably improve it by periodically adding
organic matter like compost, manure, or grass clippings. Organic matter helps
to lighten a predominantly clay soil and it helps sandy soil retain water and
Also check to see if your soil is packed down from lots of use or heavy clay
content. This makes it harder for air and water to penetrate, and for grass
roots to grow. To loosen compacted soil, some lawns may need to be aerated
several times a year. This process involves pulling out plugs of soil to create
air spaces, so water and nutrients can again penetrate to the grass roots.
Most lawns need to be fertilized every year, because they need more nitrogen,
phosphorus, and potassium than soils usually contain. These three elements are
the primary ingredients found in most lawn fertilizers. It's important not to
over-fertilize - you could do more harm to your lawn than good - and it's best
to use a slow-release fertilizer that feeds the lawn slowly. It's also important
to check the soil's pH. Grass is best able to absorb nutrients in a slightly
acidic soil, with a pH of 6.5 to 7.0. Acidic soil can be "sweetened"
with lime; soil that's not acid enough can be made more sour by adding sulfur.
Have your soil tested periodically to see whether it needs more organic matter
or the pH needs adjusting. Your county extension agent (listed in your phone
book under county government) or local nursery should be able to tell you how
to do this. These experts can also help you choose the right fertilizer,
compost, and other "soil amendments," and they can advise you about
aerating if your soil is compacted. If a professional service takes care of
your lawn, make sure it takes these same steps to develop good soil. There's no
getting around it: your lawn's health is only as good as the soil it grows in.
2. Choose a Grass Type That Thrives in
The right type of grass - one that suits your needs and likes the local weather
- will always give better results. Grasses vary in the type of climate they
prefer, the amount of water and nutrients they need, their resistance to pests,
their tolerance for shade, and the degree of wear they can withstand.
If you are putting in a new lawn, it will be worth your while to do some research
to identify the best grass type for your needs.
If you're working with an established lawn that fails to thrive despite proper
care, you might consider replanting with a different type of grass.
Why struggle to grow grass that's susceptible to fungal disease if you live in
a humid climate, or attempt to cultivate a water-loving species if you live in
an area with water shortages? Grass that is well adapted to your area will grow
better and resist local pests and diseases better.
3. Mow High, Often and With Sharp
Mowing high - that is, keeping your lawn a bit long - will produce stronger,
healthier grass with fewer pest problems.
Longer grass has more leaf surface to take in sunlight. This enables the grass to
grow thicker and develop a deeper root system, which in turn helps it survive
drought, tolerate insect damage, and fend off diseases. Longer grass also
shades the soil surface keeping it cooler, helping it retain moisture, and
making it difficult for weeds to germinate and grow.
A lawn's ideal length will vary with the type of grass, but many turf grass
species are healthiest when kept between 2-1/2 and 3-1/2 inches. You may have
to readjust your mower - most are set too low.
It's also important to mow with sharp blades to prevent tearing and injuring
the grass. In addition, it's best to mow often, because grass adjusts better to
frequent mowing. The rule of thumb is to mow often enough that you never cut
more than one-third of the height of the grass blades. Save some time and help
your lawn and the environment by leaving short clippings on the grass - where
they recycle nitrogen - rather than sending them in bags to the landfill.
You don't have to grow a foot-high meadow to get good results. Just adding an
inch will give most lawns a real boost.
4. Water Deeply But Not Too Often
Watering properly will help your lawn grow deep roots that will make it
stronger and less vulnerable to drought. Most lawns are watered too often and 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, whereasfrequent
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. Even in very dry areas
though, no established home lawn requires watering daily.
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
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 could 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.
