Mowing
Mow overseeded bermuda grass at 1 inch before the grass gets taller than 1 1/2 inches. Recycle nutrients by not collecting the clippings unless they accumulate heavily on the surface. Dormant bermuda grass that has not been overseeded need not be mowed.

Fertilization
Do not fertilize bermuda grass that has not been overseeded. For overseeded bermuda grass, apply 1/2 pound of nitrogen per thousand square feet in December and February. In the absence of a soil test, use a complete (N-P-K) turf-grade fertilizer with a 3-1-2 or 4-1-2 ratio (for example, 12-4-8 or 16-4-8).

To determine the amount of product required to apply 1 pound of potash per thousand feet, divide 100 by the third number in the fertilizer ratio. For example, for a 6-6-12 fertilizer, divide 100 by 12. The result is 8.3 pounds of product per thousand square feet: 100/12 = 8.3

Irrigation
Dormant bermuda grass may have to be watered periodically to prevent desiccation, especially when warm, windy weather prevails. Watering is particularly important for lawns that have been overseeded.

Weed Control
Apply broadleaf herbicides as needed to control weed such as chickweed, henbit, and hop clover. Selective herbicides can be applied in November or December to lawns that have not been overseeded to control annual bluegrass (Poa annua) and several winter annual broadleaf weeds.
