If lime is recommended, apply as directed any time during the cool months. Lime takes several months to reduce acidity.
Fertilize warm-season grasses when they are growing and will use the nutrients. This is a couple of weeks after spring green-up and until early fall. Fertilization other than this time frame is either wasteful or harmful to the turf and environment. Centipedegrass is fertilized lightly two or three times per season, and carpetgrass is fertilized only once in spring. St. Augustine grass and zoysia are fertilized not more than three times each season, while bermudagrass gets four applications. Avoid fertilizing in fall to avoid brown patch disease and freeze damage.
