Scutch grass is a common weed with long, tough roots that can be difficult to remove from your garden. Its scientific name is Cynodon dactylon, but it's also known by many other common names, including Bermuda grass, couch grass, devil's grass, Indian doab, and wiregrass. In some regions, it's also called star grass, Durban grass, or sweet grass. Regardless of the name you use, scutch grass is a hardy plant that can quickly take over your yard if left unchecked. To avoid this, regular maintenance and careful weeding is essential to keep your lawn looking its best.
