Grassy Weed – Bull Paspalum

(Paspalum boscianum)

Bull Paspalum – also referred to as Thin Paspalum and Bull Crowngrass – is an annual grassy weed. Preferring sandy soils and open habitats, Paspalum boscianum is typically found growing in disturbed areas, dry sites and sometimes lawns. Bull Paspalum thrives mainly in the southeastern United Sates.       

Identifying Bull Paspalum -

Bull Paspalum can be identified as a thick, annual annual, forming unsightly clumps in turfgrasses. It has a short ligule and narrow collar with smooth, loose sheaths and a prominent midvein. Its blades are flat, but wavy along edges, also with a prominent midvein. They are sparsely hairy along the edges and near the ligule, and are tinged purple in color.

Bull Paspalum flowers during warm months, producing small, inconspicuous white flowers.

Bull Paspalum Control -

Bull Paspalum is a very common invader of disturbed areas and frequently shows up in warm season lawns and other landscaped turfgrass areas. Because it forms thick, dense clumps, it is difficult to remove this grassy weed using cultural methods without creating bare patches in turf.

Bull Paspalum

         Scotts LawnService recommends cultural weed control practices to reduce Bull Paspalum in your lawn and landscaping. This is due to the limited number of selective weed control products options to kill this weed. However, this weed can be controlled with non-selective weed controls such as Round-Up, which will kill this weed and surrounding turfgrass.  Re-seeding may be necessary to repair treated areas where Round-Up is used.
