Dollarweed

Dollarweed is the main weed problem for St. Augustinegrass lawns. With round, shiny leaves (about the size of a silver dollar, hence the name), dollarweed thrives in wet areas. While there are chemicals that kill dollarweed, they're often harmful to other plants, as well as animals. Your best bet is to control this weedy pest by hand-pulling, and not overwatering your lawn.
