Collapse ▲Description
Bermudagrass (Cynodon species) is a medium- to fine-textured warm-season turfgrass that spreads by rhizomes and stolons. It has excellent heat, drought, and salt tolerance but does not do well in shade. Bermudagrass is the most widely used species on athletic fields and golf course fairways / tee boxes due to its high wear tolerance and rapid recovery. It can also be a very invasive and hard to control weed in some turf settings. Bermudagrass can be confused with nimblewill. However, nimblewill has a membranous ligule, which can be distinguished from the hairy ligule of Bermudagrass. Bermudagrass is also often confused with zoysiagrass, but zoysiagrass has hairs standing upright on the leaf blade, whereas Bermudagrass does not. Zoysiagrass is also stiff to the touch and offers more resistance to your hand than Bermudagrass. Zoysiagrass leaf vernation is rolled whereas Bermudagrass leaf vernation is folded. There are many different hybrids of Bermudagrass that range from fine to coarse in leaf texture. As a weed, Bermudagrass is sometimes referred to as wiregrass.

Bermudagrass as a Weed
Cultural Control
Most turfgrasses are difficult to control within another turfgrass. Therefore, turf managers should select clean seed or vegetative sources for establishment, use an adapted turfgrass species and cultivar for their location, and use proper mowing and fertilization techniques to maintain a dense, actively growing, desired turf. Digging or removal with hand or mechanical equipment, for example a sod cutter, is one way to control undesired perennial turfgrasses. You may spot treat an infested area with an appropriate non-selective herbicide, realizing it will also kill the desired turfgrass.
