Buffalo grass (Buchloe dactyloides), a native North American turfgrass, grows primarily in the Great Plain states and Texas and is sometimes planted in Alabama as a warm-season grass. Use buffalo grass to overseed winter grass from April to July whenever your cool-season grass begins to get stressed from heat. In the late fall, overseed the buffalo grass with a cool-season grass that's suitable for Alabama. This grass performs best in sunny locations and displays high drought tolerance.
Move furniture and other objects, such as grills or play areas, off your lawn. Mow over your existing lawn to cut it as short as possible.
Rake your turf with a grass rake to loosen the top 1/4 inch of soil before planting. Pick up rocks and debris that can get in the way of buffalo grass seed germinating.
Sow buffalo grass seed over your lawn, applying approximately 16 seeds per square inch, working by hand for small areas or with a mechanical spreader for larger areas.
Rake the lawn again to cover the grass seed with 1/4 inch of topsoil. This prevents the seed from blowing away before it can germinate.
Water the soil until the ground becomes moist, but not sopping. Water the grass until moist twice a day, once in the morning and again in the evening.
