Centipede grass should be planted in the spring or early summer in the southern states of Georgia, Louisiana, Mississippi, Alabama, Texas, Arkansas, South Carolina, parts of North Carolina and north Florida to truly flourish The salty conditions of much of South Florida's soil is unsuitable for Centipede grass to thrive. The ideal time to sow is April, May, June and July. Do not plant in the fall or winter because centipede grass is very sensitive to cold weather and often the southern states are struck by unpredictable frost in the fall and winter. Planting centipede grass seeds in the fall and winter will often result in death of the seeds or very poor results because of heavy frost or freezing conditions which will render the seeds unable to truly germinate and thrive.
In the spring or early summer till the soil completely utilizing a tiller. By tilling and planting in the spring and early summer weed growth is removed before it is firmly established. This allows the seeds to germinate without weed competition. Once the soil is completely tilled, give the ground a rest which allows soil to settle and any remaining weeds to sprout again. It is ideal to wait one week and then re-till the soil so any weeds can be easily removed before the centipede grass is sowed. Spring is always an ideal time for tilling to remove young weeds before they become firmly established.
Centipede grass should be fertilized in the spring or early summer. Once the centipede grass germinates it is time to fertilize. The first application of fertilizer should be done approximately 45 to 60 days after the day of planting. Use a nitrogen and potassium fertilizer that contains no phosphorous. A 15-0-15 mixture is ideal. Make sure the fertilizer contains iron. Lightly spread the fertilizer using a spreader and water thoroughly. Do not fertilize the centipede grass again until the following spring. You should only fertilize centipede grass once a year in the spring or early summer for ideal growth.
