Spotted spurge is a broadleaf annual that grows close to the ground in a fast-spreading mat. Its small leaves are green with a brown-red spot on top. Cut stems exude a milky liquid.
Spotted spurge reseeds heavily. A high-mowed, well-fertilized and vigorous lawn provides tough competition. Pull isolated plants before they seed. Spot-treat with a postemergence weed killer and use appropriate preemergence herbicides to prevent new weeds.
