Water your lawn in the early spring right after the last frost for two weeks to promote weed growth. It is easier to kill off weeds when they are vigorously growing and have plenty of foliage for spraying herbicide. In addition, removing weeds before sowing Bermuda is essential for preventing the weeds from competing with your turf grass for the soil's nutrients.
Spray your lawn with a herbicide that contains glyphosate. Apply the herbicide to the crown of weeds down to their base. Reapply the herbicide in a few days.
Till the soil to break up any large clumps of dirt. Use a rake to grade the soil away from the house to the perimeters of the yard. The grade should be a gentle slope to prevent your Bermuda grass from growing in standing water after it rains, because excessive water promotes fungal diseases.
Spread 1 lb. of slow release nitrogen fertilizer every 1,000 square feet. Water the soil thoroughly. Pour half of your Bermuda grass seed into a seed distributor. You want to distribute 1 lb. of grass seed every 1,000 square feet. Distribute the grass seed vertically across the yard.
Pour the rest of the grass seed in your seed spreader and distribute horizontally over the yard. Cover the seed with 1/8 of an inch of compost. Fill a lawn roller halfway with water and push back and forth across the yard to achieve adequate soil to seed contact.
Water the lawn thoroughly. Keep the soil moist by watering three times a day starting in the morning and ending in the afternoon.
