Bermuda grass germinates within 10 to 30 days of planting, according to the University of California. Because of the 20-day window until seedlings emerge, gardeners must adjust their gardening schedules to keep the soil moist during that time. Certain factors slow down germination time. Both improper sowing and lack of soil fertility will prolong germination. Gardeners can speed up the process or increase the likelihood that their Bermuda grass seed will germinate by adding additional nutrients to the soil.
Using more than the recommended rate of Bermuda grass seed slows down establishment times, according to the University of Minnesota. When too many grass seeds have been sown, they compete with one another for the soil's nutrients and moisture. The result is a longer germination time. To avoid prolonging your germination time, distribute Bermuda grass seed at a rate of 1 lb. per 1,000 square feet, as suggested by Texas A&M University. Measure out the proper amount for the entire yard and divide it in half. Sow one half horizontally and the rest vertically to achieve adequate coverage.
Distributing a starter fertilizer high in phosphorous promotes seed germination. Phosphorous bonds DNA, which holds genetic codes, with RNA, which reads the codes. Phosphorous also promotes healthy grass root development. Use a starter fertilizer with an NPK amount of 16-20-0 at a rate of six lbs. per 1,000 square feet, as recommended by the University of California. Work the starter fertilizer into the first 2 to 4 inches of topsoil before seeding your lawn with Bermuda grass.
Dried-out soil will not promote seed germination or help seedlings survive. Water your lawn when you see two-thirds of the soil dry out or turn lighter in color, says Lance Walheim of the National Gardening Association. Apply enough water to moisten the top 6 to 8 inches of topsoil. You can check moisture depth by pressing a screwdriver in the soil and checking the soil at the bottom of your hole.
