Florida betony (Stachys floridana) is a hard-to-control perennial weed that emerges in the fall and becomes a problem in late winter and spring. It is easily recognized by the very characteristic white tuber that resembles a rattlesnake rattle. This weed also has square stems and produces white to pink flowers in the spring. It is found in the southern United States west to Texas and north to Virginia.

Cultural Control

Skip to Cultural Control

Perennial broadleaf turf weeds are capable of living more than two years. They thrive in weak, thin turf; golf fairways and roughs; home lawns; playfields; and industrial grounds. Proper turf maintenance is the key to control of this weed. First, select adapted turfgrass cultivars for your area and then properly fertilize, mow, and water to encourage dense growth.
