Importance of a Lawn

The lawn and other landscape components should complement the house and provide a pleasant area for family activities.

Importance of a Lawn

Sound establishment and maintenance practices will improve the appearance of your lawn.

Importance of a Lawn

Unkept Lawns reflect the people who live there and are unappealing to the neighborhood.

Selecting Turfgrasses

Do not make the assumption that all grasses are alike. There are several grasses to choose from and they require various conditions and treatment for good growth. They also differ in appearance. Color variation is easily seen here.

Types of Grasses

Warm Season Grasses

• Common Bermuda

• Hybrid Bermuda

• Centipede

• St. Augustine

• Zoysia

• Bahia

• Seashore Paspalum

Cool Season Grasses

• Tall Fescue

• Fine Fescue

• Rye Grass

• Kentucky Bluegrass

Types of Cool Season Grasses

• Tall Fescue• Fine Fescue• Rye Grass• Kentucky Bluegrass

Tall Fescue

• Most heat tolerant cool season grass

• Easily established from seed

• Very economical

Tall FescueThe biggest problem of fescue is that it doesn’t spread and becomes clumpy and spotty. It lacks rhizomes and stolons to fill in bare ground in the landscape.

Tall FescueReseeding is recommended each fall to reduces the gaps between clumps.

Tall Fescue

• Should be mowed to about 3 inches.

• Shorter mowing will stress the grass especially during summer.

Tall Fescue

• Very Coarse Texture

• Wide Leaf Blade

• Unappealing to some

Tall Fescue

Poorly managed fescue lawns quickly become unattractive.

Fine Fescue

• Not widely used in Georgia

• Less heat tolerance than tall fescue

Fine Fescue Tall Fescue

FescueVarieties of fine fescue are being researched and there is promise of heat and drought tolerant varieties for the south.

Kentucky Bluegrass

• Most popular lawngrass in the Northern United States

• Limited to only the northern part of Georgia due to poor hear tolerance

• Medium Textured Grass

• Found commonly in mixed stands with fescue

Kentucky Bluegrass

Kentucky BluegrassThe boat shaped leaf tips readily distinguish Kentucky Bluegrass.

Ryegrass• Two types: Annual and

Perennial

• Not usually grown in Georgia as a single grass lawns.

• Used mostly to overseed dormant warm season grasses for winter color.

Warm Season Grass Characteristics• A major disadvantage is that they become dormant and

turn brown in the winter.• They can be overseeded with ryegrass to provide green

color in the winter.• Grow during late spring, summer and fall.

Types of Warm Season Grass

• Common Bermuda• Hybrid Bermuda• Centipede• St. Augustine• Zoysia• Bahia

Warm Season Grasses- Vegetative Reproduction

Most of the finest grasses are hybrids and must be reproduced vegetatively. This can be slow if sprigged or plugged and expensive if completely sodded.

Bermudagrasses

• Most popular warm season grass

• Most adapted grass to Georgia

• Can be mowed at short desirable lengths

Bermudagrass• Selecting and breeding of bermudagrass has been

present since 1950.• The University of Georgia Coastal Experiment

Station in Tifton has been a leading producer of successful cultivars.

Bermudagrass Seed Heads• Seeds are most

abundant on common bermuda.

• A very unattractive characteristic.

• Hybrid breeds have been selected for their lower number of seed heads.

Four Groups of Bermudagrass

• Common (Arizona Common)

• Improved Common or Seeded- have better color, density, or traffic tolerance than common bermuda, depending on the type.

• Hybrid- produces sterile seed and can only be propagated vegetatively. Has a finer leaf blade than common.

• Ultradwarf- relatively new, they are selected for their low mowing height. Used mostly for golf greens.

Common Bermudagrass

• Distinguished by its coarse texture and open habit of growth.

• Most widely used lawngrass in Georgia• Grows very easily• Can be reproduced by seeds

Bermudagrass

The difference in texture of the finer hybrid bermuda and the more course common Bermuda can be seen here.

Bermudagrass HybridsHybrid bermuda grasses can be very beautiful if given the extra care that is required.

Bermudagrass Hybrids

Bermudagrass HybridsTifgreen 328 is best used on golf greens, but can be used on lawns.

Bermudagrasses for LawnsTifway 419 is the most popular hybrid bermuda used for lawns. It is also well suited for golf fairways and football fields.

Bermudagrass- Ultradwarf• Used only for golf greens • Selected for their close mowing ability• Have a high maintenance requirement

Bermudagrass Characteristics

• Bermuda is commonly confused with Zoysia

• The leave angles are different for the two species. Bermuda leaves are at 45º angles, while Zoysia leaves are at 80 º angles.

• Zoysia is also much stiffer and spindly to the touch than Bermuda.

Zoysiagrass• Provides a neat and

clean appearance.

• A slow grower

• Cannot be grown from seed

• Zoysia sod is expensive and the sprigs grow slow.

ZoysiagrassZoysia can spread by stolons and rhizomes, shown here, as does bermuda.

Zoysiagrass vs. Bermudagrass

Zoysia and bermuda are difficult to tell apart. Bermuda leaves, on the right, stand at 45º angles to its stems. Zoysia, on the left, has leaves that stand at about 80º to its stems.

Zoysiagrass Hybrid Bermuda

ZoysiagrassZoysia makes a beautiful lawn but grow slowly and requires a lot of extra care. It can be grown in light shade, unlike bermuda.

ZoysiagrassThese plots were planted at the same time, ten months ago. The zoysia has not spread as well as the bermuda.

Meyer ZoysiaThe most widely used cultivar. Is known for its improved growing rate.

El Toro ZoysiaThe El Toro variety is a high quality hybrid. This fine textured grass has a low growth habit, attractive color and high density. However, its cold tolerance is less than other varieties of Zoysia.

Emerald Zoysia• Very fine leaf texture• Poor cold tolerance

Centipedegrass• Low Maintenance

Required

• Easily and economically established from seeds.

• Less mowing and fertilizer needed than other grasses

Centipedegrass

• Ability to grow in the sun or shade

• Poor cold tolerance• Yellow-green color is

unattractive to some homeowners

Centipedegrass

• Coarse Texture

• Opposite leaf arrangement

• Single stem seed head

St. Augustinegrass

Very popular in the Coastal Plains Region of Georgiabut also grown successfully in the Athens-Atlanta area.

St. AugustinegrassHas large flat stems and wide coarse leaves. Lacks seeds, so must be propagated vegetatively. A very aggressive grass that spreads rapidly.

Centipede St. AugustineSt. Augustine is sometimes confused with centipede. Centipede (right) which has a narrower leaf and whose leaves are opposite on the stem. St. Augustine's leaves (left) are alternate on the stem and are much taller.

BahiagrassNot usually recommended as a lawn grass, with the rapid production of unattractive seed heads being the most objectionable trait. Bahia is used mostly where quality is not important, such as roadsides and ditches.

Seashore Paspalum

• Recently developed in Florida

• Tolerates poor soils• High salt tolerance (Can

even be irrigated with ocean salt water!)

• Highly suitable for coastal regions

Seashore Paspalum

• Used mostly on golf courses near the coast

• Can be mowed to an 1/8 inch height but ½ to 1 ½ is recommended.

Seashore Paspalum• Seed heads grow

quickly, however not enough viable seed is produced to be effective.

• Vegetative propagation is used with stolons, rhizomes, and sprigs

Selecting a Grass• Matching the proper

grass to a site can be confusing.

• Remembering all the characteristics of each grass is difficult for a beginner.

• Find a grass that best suits your situation
