How to Get Rid of Wiregrass (Bermudagrass) in Flowerbeds

Wiregrass (Bermudagrass, Cynodon dactylon) is a perennial that spreads aggressively via underground rhizomes. Digging often fails because fragments regrow. Chemical control is usually necessary.

Glyphosate (Roundup): Effective but non-selective — kills any plant it touches. In mixed beds, apply with a paintbrush to target only grass blades. Water the area well 2 days before application to boost uptake. Multiple applications over several weeks are typically needed.

Fluazifop (selective grass killer): Sold as "grassy weed control," it kills grasses but spares most ornamentals. Check the label for a list of tolerant and sensitive plants. Follow directions precisely. Available in ready-to-spray bottles.
