St.
Augustine is a turf grass widely
adapted to the world's warm, humid (subtropical) regions. It
is believed to be native to the coastal regions of both the
Gulf of Mexico and the Mediterranean. In Florida, St. Augustine
is the most common planted turfgrass in urban, coastal areas.
It can be grown in a wide variety of soils, but grows best in
well-drained, fertile soils. To produce an acceptable quality
lawn, St. Augustinegrass requires WATERING
and FERTLIZING.
ADVANTAGES - St. Augustinegrass produces a dark to blue-green,
dense turf that is well adapted to most soils and climatic regions
in Florida. It has good salt tolerance and certain cultivars
will generally tolerate shade better than other warm-season
turfgrasses. St. Augustinegrass establishes from sod quickly
and easily. Several different types of St. Augustinegrass sod
and plugs are available from garden centers and sod installers
throughout Florida.
DISADVANTAGES - St. Augustinegrass, like most turfgrasses,
has certain cultural and pest problems which may limit its use
in some situations. The coarse leaf texture is objectionable
to some people. It requires irrigation to produce a good quality
turf, and does not remain green during drought conditions without
supplemental irrigation. Excessive thatch buildup can occur
under moderate to high fertility and frequent irrigation conditions.
It wears poorly, and some varieties are susceptible to cold
damage. The major insect pest of St. Augustinegrass is the chinch
bug and sod
webworms.

Bahiagrass
was introduced from Brazil in 1914
and was originally used as a pasture grass on the poor sandy
soils of the southeastern United States. Several varieties have
become available for use as lawngrasses. The ability of bahiagrasses
to persist on infertile, dry soils and their resistance to most
pests have made them increasingly popular with homeowners.
ADVANTAGES - Bahiagrass can be grown from seed which
is abundant and relatively inexpensive. Once established, these
grasses develop an extensive root system which makes them one
of the most drought tolerant lawngrasses. Bahiagrass produces
a very durable sod which is able to withstand moderate traffic.
In addition, bahiagrasses have fewer pest problems than any
other Florida lawngrass, although mole crickets can severly
damage it.
DISADVANTAGES - Bahiagrasses have a relatively open
growth habit and the tall unsightly seedheads that are produced
continuously from May through November. The prolific seedheads,
plus the very tough leaves and stems make bahias difficult to
mow. The coarse texture of several bahia varieties reduce their
visual quality. Bahiagrasses are not well adapted to soils having
high pH (alkaline soils) and grow poorly in areas subject to
salt spray. They often appear yellow in spring and fall due
to lack of iron and they can be seriously damaged by insects
called mole crickets. Bahiagrass has low tolerance to most currently
available postemergence grass herbicides. This makes weed control
difficult in bahiagrass turf.

Bermudagrass
is planted throughout Florida primarily
on golf courses, athletic fields, tennis courts, and bowling
greens. They are primarily used in areas where fine-textured,
high quality turf is essential for sports activities, and maintenance
budgets are adequate. Bermudagrass is native to Africa where
it thrived on fertile soils. Today, most of the bermudagrass
used for turf in Florida are hybrids of two different species.
ADVANTAGES - Bermudagrass produces a vigorous, light
to dark green, dense turf that is well adapted to most soils
and climatic regions in Florida. Bermudagrass has excellent
wear, drought and salt tolerance and is a good choice for ocean
front property. It establishes rapidly and is competitive against
weeds and, depending on the variety, is available as seed, sod
or sprigs.
DISADVANTAGES - Bermudagrass has a large number of cultural
and pest problems which restrict its use in many Florida situations.
It is not suitable for most home lawns because of the need for
restricted use pesticides to control nematodes and insects.
It also requires the most maintenance for an acceptable apperance
of any Florida turfgrass.
