I don't use chemicals, so my only defense is hand pulling the runners when they encroach on the veggie garden perimeter. Don't have an issue with them in the garden itself. The lawn is a totally different story. :(

Round up and an old paint brush or one of those throw away spongy ones. Make round up and put in bucket and use brush/sponge and paint on so as not to disturb other plantings. Takes a couple sessions, but it worked for me.

I successfully got rid of it in my Saint Augustine lawn with Ortho's Weed B Gone for Southern Lawns.

There are several kinds of weeds it didn't work on, but the Dollar grass is gone and the Saint Augustine is doing fine.

Be sure to read the instructions because I've seen people get in trouble using it. For example, if you mix it too strongly or use it in the heat of summer, it will take out your Saint Augustine too.

RE: Dollarweed

A product called "Atrazine" is very effective in killing Dollarweed. Buying it in bags, as a weed-n-feed formulation, is ridiculously over-priced! A bottle of Atrazine lasts me for years. And, that's using it in the garden and the lawn.

I think Atrazine may be harmful to many ornamentals and, I wouldn't "spray" it around my vegetables. Here's how I apply Atrazine in my landscape and vegetable gardens;

I put on a rubber/nitrile glove first, to prevent any of the herbicide from coming in contact with my skin. Then, I put on a cotton glove over the rubber one, as 'the wick". Beforehand, I prepare a plastic margarine tub with Atrazine mixed according to mfg instructions. I dip my gloved hand into the Atrazine and grab the offending weed (Dollarweed) letting it slip through my lightly clenched hand as I draw my hand back. I keep dipping my hand into the Atrazine to make sure the cotton glove stays saturated with the herbicide. This method has never resulted in the unintentional damage of my plants.

I do the same thing with Roundup when targeting weeds in my lawn. There is just no way to spray Roundup on your lawn without overspray killing some of your sod.

This method sounds very labor intensive but, with just a couple of applications you can make HUGE strides in eradicating problem weeds.

With typical weeds, you should kill the weed before it goes-to-seed. Once you allow the weeds to go-to-seed, you will have to fight the germinated seeds (weeds) until you catch up.

Of course, there are "pre-emergent" herbicides for dealing with seeds. Whole nudda story.

Did you know that Dollarweed is edible? I'm tellin ya, it is!

If you just have a little bit of dollarweed, it is possible to dig it out. You must patiently work to get every last bit of root (they are not very deep). If you get it, you're done. I have done that in flowerbeds. Don't wait! Get it while it's small.

If you have a bad infestation, I second the motion for Ortho's Weed B Gone for Southern lawns. I had it in a groundcover and the weed B Gone did not kill the ground cover. It did kill the weed when I sprayed it twice, one week apart. Be sure there is not rain coming for at least 24 hours after spraying.

just an FYI...
dollarweed is edible
its even a close relative to Ginkgo Biloba
(people pay good $ for Ginkgo Biloba)

it even can help with erection....
(supposedly)

Plants are natural chemical factories. These weeds have a chemical, like celery, that helps the aorta and blood vessels relax. They do that by increasing the amount of nitrous oxide available and that can lower blood pressure. In India, Centella has been used for that purpose for some 3,000 years. Nice of modern science to confirm it. The plant has a host of other properties as well from affecting blood cell development to wound care to reducing edema. It’s a little plant that can. By the way, Centella means “little coin” because the leaf surface is shiny and reflects light (and why all of the money names.) Erecta is upright. Hydrocotyle is from Greek meaning flat cup �" the leaves can hold water �" and Bonariensis translates into “of Buenos Aires” which is another way of saying South America, where they thought it came from originally.

The most common is the native pennywort, the round Hydrocotyle bonariensis, and the main lawn interloper. It’s about the size of a silver dollar under good conditions. Its stem attaches to the center of the leaf. Next is its close cousin, the Marsh Pennywort, or Hydrocotyle umbellata (um-bell-AY-tuh which means with umbels.) Equally edible, one often sees wading limpkins running across the top of floating masses of Marsh Pennywort, hoping to turn bug into bird. The Hydrocotyle bonariensis and Hydrocotyle umbellata are similar in appearance except the latter can easily grow far larger.
