Virginia buttonweed is a tough perennial that spreads by seed, rooting stem nodes, and mower-dispersed fragments. It resists standard broadleaf herbicides. For fescue or zoysiagrass, use triclopyr. For bermudagrass or centipedegrass, use a broadleaf weed killer blend. Apply at least three times at six-week intervals. Alternating with imazaquin can improve control. Glyphosate kills it but also kills desirable grass. Start early and stay persistent.
