Recent research in North Carolina has shown that this problem can be caused by several different factors. Improper Mowing and Fertilization have been indicated as factors in experimental plots where centipede decline developed. More thatch accumulated at the higher mowing height with high nitrogen and caused the stolons to be above the soil. These stolons are more susceptible to damage by cold weather. More centipede decline usually occurs in the spring and summer following very cold winters or following winters with unusually warm weather and then late cold periods.
Excess nitrogen increases the thatch and reduces cold and drought tolerance of centipedegrass.
Usually not more than 1 pound of nitrogen per 1000 sq. The use of fertilizers that are high in potassium and low in nitrogen may help to reduce stress during the summer and winter. This grass has grown well on clay soils without any fertilization for many years. Centipedegrass has a naturally light green color when managed properly. If a darker green turf is desired in the lawn, another type of grass such as bermudagrass or zoysiagrass should be considered.
