Common lespedeza is a prostrate growing summer annual. Three oblong, smooth leaflets, all joining on a common petiole, have a prominent mid-vein. Stems are wiry, prostrate and freely branching. The flowers of common lespedeza are pink to purple and are found in the leaf axils. Lespedeza is commonly found on soils with low fertility. Common lespedeza is found in the southern United States, north to New Jersey and west to Texas and Kansas.
Use of good turf management programs, including a sound fertilization program, to form dense stands of turf grass may assist in prevention of lespedeza infestation.
For optimum control, make your post-emergence herbicide application to lespedeza that is actively growing and in the seedling to flower stage of growth.
