Because sacaton is a coarse grass that grows rapidly, it should be managed carefully to make full use of the forage and to maintain sacaton flats in a highly productive condition. Sacaton stands should be fenced to control use and protect upland grasses from heavy grazing. These areas can be used most effectively by grazing them in the early spring. After the grasses on the upland ranges have begun to grow, livestock should be moved from the sacaton flats and kept off until fall. The coarse, unpalatable old growth may be removed by burning every three or four years. It is advisable to divide a flat into three or four parts and to burn one part each year. The plants will suffer the least fire injury if they are burned during the late winter or early spring months before growth begins and soils are moist.
