Grasses used in Oklahoma are turfgrass species and cultivar that is adapted to the environmental conditions of Oklahoma and that fits your personal needs and interests. The grass should also be suited to the physical or environmental limitations of the planting site, such as shade, no supplemental water, or poor soil conditions. Bermudagrass, buffalograss, and zoysiagrass are the warm-season (grows in the summer and dormant in the winter) turfgrass species most commonly planted in Oklahoma. Occasionally, cool-season turfgrass species, such as tall fescue, Kentucky bluegrass, and perennial ryegrass are planted on shaded sites because the warm-season turfgrasses cannot tolerate shade. Cool-season turfgrasses, such as tall fescue and Kentucky bluegrass can also be successfully grown in full sun, but requires more frequent watering during the summer than bermudagrass to prevent wilting, thinning, and a loss of turf density. Thus, cool-season turfgrasses may be utilized in full sun only when a convenient means of irrigation is available.

Cool-season grasses:
Tall Fescue - Tall fescue is adapted to a wide range of soil and climatic conditions, but performs best on well drained clay soils in the "transition zone." Tall fescue demonstrates good shade tolerance in the southern region and remains green year-round under irrigated conditions. The improved turf-type tall fescues are finding widespread acceptance as lawn grasses in the transition zone. And, in the southern region under moderately shaded conditions, tall fescue is gaining in popularity. With proper management tall fescue can survive in densely shaded sites that warm season grasses cannot tolerate. Also, the improved tall fescues retain color during the winter months and provide a year-round green lawn. The best grass species that we recommend for shady conditions is the turf-type tall fescue.

Perennial ryegrass - Perennial ryegrass can be utilized for overseeding into dormant warm-season turfgrasses or for soil stabilization during the fall and spring when a turf cover is rapidly needed. Perennial ryegrass is commonly seeded into an established bermudagrass turf when a fine textured, green turf cover is desired from October through April.

Kentucky bluegrass - Kentucky bluegrass is a persistent and attractive species that is used in many home lawns, institutional grounds, parks, and athletic fields. This species has a medium to fine leaf texture and a medium- to dark-green color when properly fertilized. It produces extensive underground stems, called rhizomes, which provide good sod-forming characteristics and superior recuperative potential when compared to most other cool-season turfgrasses. Kentucky bluegrass is cold tolerant, wear tolerant, and moderately heat and drought tolerant. It makes optimum growth during the spring and fall and becomes semi-dormant under prolonged periods of heat and drought. It usually recovers quickly from dormancy with the advent of cooler temperatures and adequate soil moisture. Kentucky bluegrass is limited for use in the cooler zones of Oklahoma.

Warm-season grasses:
Bermudagrasses - Bermudagrass is an aggressive, warm-season turfgrass species that spreads rapidly by above-ground (stolons) and below-ground (rhizomes) stems. It is the best-adapted turfgrass for full-sun areas in Oklahoma due to its excellent heat and drought tolerance during the summer and its sufficient winter hardiness. Bermudagrass cultivars having a fine texture (relative measure of leaf-blade width) and a high turf density (number of leaves or stems per unit area) are best suited for areas such as lawns, athletic fields and golf courses.

Zoysiagrasses - Zoysiagrass is fine to medium-textured warm-season turfgrass that spreads by stolons and rhizomes. Its winter hardiness and its ability to grow under light shade are its desirable features. Its slow establishment rate is its greatest liability. Zoysiagrass requires more frequent watering to prevent wilting than bermudagrass but has lower annual fertilizer requirements. Zoysiagrass, like the fine-textured bermudagrasses, should only be utilized for lawns when a top quality and high-maintenance turf is desired.

Buffalograss - Buffalograss is a warm-season, sod-forming, native prairie grass that spreads by stolons. It has a fine texture and a grayish-green color. It has excellent tolerance for the heat, drought, and cold conditions found in Oklahoma. Buffalograss is best suited to full-sun sites in areas of Oklahoma receiving 12 to 25 inches of rainfall per year. It grows best on heavy-textured soils and has some tolerance of alkaline soils. Buffalograss is the best choice for unirrigated lawns and general turf areas of western Oklahoma. It produces numerous seed heads which may distract from the general appearance of the turf. Buffalograss can be established from processed and treated seed or from sod.

USING THE QUICK GRASS SEED CALCULATOR:
Simply select your unit of measurment and enter your area value(s). The total square footage (if appropriate) and seed required to cover your area will be automatically calculated.

USING THE ADVANCED GRASS SEED CALCULATOR:
Enter as many grass areas/lots as you need. If you have lots with areas not needing seed (e.g. buildings, driveways etc.) enter the dimensions of those under 'Voids' to be subtracted from the total area. Clicking the '+' button will add a new area; clicking '-' will remove the associated area.
