Dollarweed, also called Pennywort, is a small broadleaf plant. The best way to get rid of it is to hand pull it, roots and all. The problem is that it grows in large patches and it replaces itself quickly so that few find pulling it up a reasonable solution. Ortho? Weed B Gon? Spot Weed Killer can help but you'll need to spray only the dollar weed and repeat applications may be necessary. Hope it works well for you!
