Are dollar weeds, dandelions and crab grass taking over your yard? Learn how they get there and how to get rid of them without expensive and unhealthy chemicals or pesticides.
First off, it's important to understand one thing about the dollar weed(and most weeds in general); Weeds thrive in poor soil and are a good sign that your lawn is either over fertilized or has unhealthy soil. The richer the soil, the more difficult it is for weeds to survive.
Now, dollar weeds may not be a problem in your entire lawn, but if you have them in any significant portion of it I would recommend treating your entire lawn as described in Step two.
Divide the area of your yard you will be treating into sections of about 250-300 sq ft (about 17' X 17'). Spread a 1 lb bag of household sugar (or dry molasses, if available) over each section of the yard until the entire yard has been treated. Be sure to complete the entire area you plan on treating before watering your lawn.
After the lawn has been treated with sugar, water the treated area(s) thoroughly. Be sure to water the sugar in well the same day or else you might be opening yourself up to another infestation: ants. Continue your regular lawn care regimen (mowing, edging, weed eating, etc...) but try to avoid over fertilizing or switch to an organic formula. Over the next two weeks you should begin to see a SIGNIFICANT decrease in the dollar weed population and, after a few more weeks with regular mowing, the weeds will likely be gone altogether.
You should treat your lawn with sugar twice a year, once in the Spring and once in the Fall.
