A healthy, thriving lawn provides many benefits: it helps
to keep air temperatures cooler in the summertime; like other plants,
grass draws carbon dioxide from the atmosphere and gives off oxygen; and
turf is an ideal outdoor carpet for recreation and entertaining.
Growing a natural, low-maintenance lawn - one that you can feel good about
and that won't take over your life - is easier than you may think.
The key to natural lawn care is to choose the right kind of grass and
to provide a healthy soil environment.
THE RIGHT KIND OF GRASS
Kentucky bluegrass, perennial ryegrass, and fine fescues are the primary
lawn species for use in Central Illinois. Kentucky bluegrass is by far
the most popular species used in home lawns in Illinois, due to high quality
appearance, hardiness, and recovery ability. Kentucky bluegrass prefers
full sun, although a few cultivars have tolerance to light shade. Fine
fescues require less maintenance and many adapt to shade. Perennial ryegrass
offers quick establishment and good wear tolerance. Perennial ryegrass
is not suggested to be used alone as a lawn grass; but as part of a lawn
seed mixture.
We at Casey's generally recommend a mix. A blend of the three grasses
allows the strength of one to cover the weakness of another. Fine fescue
germinates more rapidly than bluegrass so it acts as a nurse grass - shading
and protecting the bluegrass seedlings until they get established. Some
areas may be shadier, so the bluegrass won't do as well there, but the
other two will take over.

MOWING AND WATERING
Keep your mower blade sharp: A dull blade injures your lawn by tearing
blades of grass, and it can pull out tender new growth. One very common
mistake is mowing lawns too short. For most lawns, a mowing height between
2 to 3 inches is best for summer. The first and last mowing of the year
should be at a height of about 2 inches; avoid scalping in spring and
allowing the grass to remain excessively high at the end of fall.
An important decision to make before summer is to either water lawns consistently
as needed throughout the season, or let lawns go dormant as conditions
turn warm and dry. Do not rotate back and forth. In other words, don't
let the grass turn totally brown, apply enough water to green it up, and
then let the grass go dormant again. Breaking dormancy actually drains
large amounts of food reserves from the plant. In general, water deeply
or not at all. Shallow watering promotes shallow rooting and weak growth.
If you decide to water a general rule is to apply 1 inch of water per
week to your lawn. This should be enough (in this area) to keep your lawn
looking good without wasting a lot of water.
CONTROLLING WEEDS AND INSECTS
Proper maintenance of a lawn will go a long ways towards controlling weeds,
insects and disease. There are general guidelines for using weed control
on lawns. Avoid windy days, as these materials can damage many landscape
and garden plants if they drift, avoid hot days (over 85 degrees F), try
to maintain adequate soil moisture, but no rain for 24 hours after application.
Don't mow for few days before and after application and use caution on
newly seeded areas. Weed killers are also available to manage annual weeds.
Pre-emergent crabgrass control prevents annual crabgrass from emerging.
Timing of application is very important, as the weed killer should be
applied before the crabgrass emerges from the soil.

White grubs are the most serious and destructive
lawn insect pests in Illinois. While not all lawns will get grubs
and the extent of grub damage varies from year to year, there are
some important points to consider concerning managing grubs in lawns.
Grubs chew on the roots of turf and can sometimes kill entire sections
of lawn. Scott's GrubEX® kills grubs before they can damage
your lawn. One application protects from grubs all season long and
the formula remains active even through heavy spring rains.

The Five Most Common Insect and Disease
Problems
|
Fusarium Blight
Fusarium roseum is characterized by a "frog-eye" pattern
or a ring of diseased grass with seemingly healthy grass in the
center. Fusarium spores germinate in warm, humid spring weather.
and send out threads which form a "cobwebby" mycelium
at the crown of the plant. When temperatures rise to the 70's infected
plants begin to rot and die. Fusarium can continue active growth
until cool weather and then go dormant. It survives the winter in
soil and reappears in the exact spot the following year. Conditions
encouraging Fusarium include: excessive thatch, excessive summer
fertilazation and improper watering. If these conditions are corrected,
disease damage may be decreased.

Fairy Ring
Fairy rings are arcs or continuous circles formed by bands of turfgrass
that are faster growing or darker green than grasses on either side.
A characteristic of fairy ring is the presence of toadstools or
mushrooms in the infected area.
Fairy ring is caused by fungi which grow in decaying matter below
the surface of the soil. The dense mass of white mycelium formed
by the fungi traps the movement of air and gasses and prevents the
penetration of water. Nitrogen becomes available to the infected
area in excessive amounts. Eventually the combination of excessive
nitrogen and toxins produced by the fungus cause the infected area
to die. Although there is no ‘magical cure’ for fairy ring, its
damage can be minimized by watering the infected area with Safer's
Soap. The soap helps water penetrate into the ring.

Rust
Bluegrasses, ryegrasses and certain bermuda grasses are
especially susceptible to rust. In the early stages
of development, lesions are viewed as yellow orange flecks
on the surface of the blades. If the
infestation is severe the leaves turn yellow, progressing from the
tip to the sheath.
In the overall view, turf takes on a rusty appearance. When walking
through turf with rust, orange-red dust comes off on shoes.
Rust is most common in July and August. The best control is a good
preventive fungicide program coupled with proper fertilization.
Turf that enters the winter with rust may be very susceptible to
winter-kill.

White Grubs
White grubs are one phase in the life cycle of various beetles.
The grub does damage by chewing and feeding on grass roots. This
allows turf to be rolled back like a carpet, and damaging grubs
are easily exposed. White grubs destroy turf from late spring through
early fall.
Bird scavenging, raccoon and skunk digging, and mole burrowing are
often signs that your lawn may contain a high white grub population.
These critters can often cause more damage than the grubs!

Sod Webworm
Sod webworms are the larvae stage of the lawn moth's
life cycle. Sod webworms damage the turf by chewing the blades.
Foliage may be almost completely striped off in patches and these
areas have a yellowish-brown appearance similar to drought damage.
All grasses are vulnerable to attack but blue and bent grasses are
susceptible to the greatest injury.
