Identifying and Controlling Dollarweed in Florida Lawns

A Florida gardener battles dollarweed (also called pennywort) that has taken over the yard. The key is proper identification: dollarweed has a stem attached to the center of the leaf, while dichondra's stem attaches at the leaf edge.

Control Options

• Glyphosate (Roundup) concentrate kills dollarweed effectively but is non‑selective; protect desirable plants.
• Cultural practices: improve drainage, reduce irrigation, and maintain dense turf to outcompete the weed.

For detailed guidance, see the Clemson University resource: Dollarweed Management.
