Riviera Bermudagrass is the premier turf type, seed propagated, winter hardy variety. Fine leaved with excellent turf density, it is the best choice for an attractive bermudagrass lawn. Sharp Bros. Seed Co. provides winter hardy bermudagrass varieties that are adapted as far north as Interstate 70. Bermudagrass is widely adapted to soil textures from sand to clay. Very traffic tolerant and able to mend open spaces in the turf. It can be invasive, moving into flowerbeds or neighboring yards. Excellent heat and salinity tolerance. Bermudagrass maintains green foliage very well as soils dry in the early stages of drought. It recovers and "regreens" when moisture is replenished after severe drought, but less rapidly than buffalograss under similar conditions.
Plantings in the northern portion of the bermudagrass belt, approximately from Interstate 70 to 300 miles south, are best performed between late May and mid-July. During this time period, soil temperatures tend to be consistently warm, facilitating germination. When planted later, seedlings may fail to develop sufficiently to survive the first winter. Bermudagrass seed is slow to imbibe moisture, requiring patience and consistent seed bed moisture management. Although established bermudagrass is strongly competitive, seedling bermudagrass is not competitive. Weed growth should be suppressed with frequent mowing, allowing sunlight to reach bermudagrass seedlings so development continues.
After establishment, bermudagrass nitrogen fertilizer rates of 0.75 to 1.5 lbs of nitrogen per 1,000 sq ft per application are generally recommended. Total nitrogen application per season would rarely need to exceed 4 lbs of nitrogen per 1,000 sq ft in order to maintain an attractive green color. Excessive nitrogen application tends to increase the growth and need to mow.
