White vinegar has long been rumored to be a safe, effective weed killer, but it wasn't until 2002 that U.S. Department of Agriculture scientists did a study on the effectiveness of using white vinegar on weeds. The Agricultural Research Service found that vinegar with concentrations of 5 percent and 10 percent acetic acid killed various weeds within two weeks, while vinegar with higher percentages of acetic acid killed the weeds within a couple of hours.
The acid in vinegar damages the leaves of weeds, drying them out and rendering them unable to make food. For this reason, the broader the leaves, the more effective the vinegar is likely to be. In the case of dollar weeds, the large, round leaves make it more likely that the vinegar will be effective. The major issue is the fact that dollar weeds like moisture and are found in wet places. You don't want the moisture to wash the vinegar off of the leaves, so spray the weeds on a hot, dry day -- the hotter, the better.
Believe it or not, widely despised Dollar weed is one of those plants of our urban settings that is actually edible. While many gardeners and homeowners are constantly trying to get rid of it, some people make a delicacy of it.
It can be eaten raw or cooked, but it’s mainly used as a salad. Those who have tried it say the taste of Dollar weed reminds of celery.
However, if you want to have a bite of this weed, be sure to make a correct identification before deciding to consume it. It’s often mistaken for Dichondra, but the main difference is in a stem. Dichondra’s stem is attached at the edge of the leaf, while Dollar Weed’s stem grows directly from the center of the leaf.
Also, don’t eat it if it grows in contaminated conditions and wash it thoroughly if a herbicide has been applied to the weed in order to control it.
Sometimes chemical control is necessary for killing dollar weeds. Most types of dollar weed herbicide are applied in spring while the plants are still young, though repeat applications may be needed. Monument, Manor, Blade, Image and Atrazine have all been found to effectively eradicate this weed. They are also safe for use on Zoysia, St. Augustine, Bermuda and Centipede grasses (provided you carefully follow instructions).
Note: Chemical control should only be used as a last resort, as organic approaches are safer and much more environmentally friendly.
