Dollarweed, also called Pennywort, is a small broadleaf plant. The best way to get rid of it is to hand pull it from the root.The problem is that it grows in large patches and it replaces itself quickly so that few find pulling it up a reasonable solution. There are, however, a plethora of avenues of attack to try. Try weed-killing chemicals. There are chemicals available including WipeOut by GreenLight which will kill the weeds but not their seeds so multiple applications will be needed. A product called Image is also an option. It?s especially good for use with St. Augustine grass. Ortho Weed B Gon Max for Southern Lawns is also safe for use on St. Augustine. Lesco Momentum Force and Lesco Drive herbicides are not registered for use on St. Augustine. If you have a different product in mind, be sure to read the fine print on the label so you know it's safe to use on St. Augustine.

I'd eliminate the weeds first and then put your lawn on a regular feeding, mowing and watering schedule. You're right - a thick, healthy turf will crowd out most weeds.
