What works on creeping charlie?

other than having lawn sprayed professionally, is there an otc product available that works to control creeping charlie?

What works on creeping charlie?
Creeping Charlie Control - Borax





You may have heard about using Borax to control creeping charlie. You have to use Borax very carefully. Boron, the active ingredient in Borax, is an essential nutrient, needed in minute quantities for healthy plant growth. Amounts even slightly over what is needed are toxic to plants. Borax can be used against creeping charlie because the weed is more sensitive to boron than grass is. Small amounts can kill creeping charlie without permanently harming the lawn. (Grass may brown a bit, but it will grow out of it.)





The problem is, boron does not dissipate or break down like standard weed-killers. If it's applied repeatedly or at too strong a rate, you will end up with an area where you can't grow anything until the boron leaches out. That may take years.





The most you should treat your lawn with borax is once each spring for two years. Here's the formula:





* Dissolve eight ounces of Twenty Mule Team Borax into four ounces of warm water, then dilute it in 2 1/2 gallons of water. This should be sprayed evenly over 1,000 square feet of lawn, no more, no less.





This appears to be noted as a drastic step by many so use it as a last resort and the VERY CAREFULLY!





Round up works very well to Kill everything like on a walkway but will also persist for a long time and nothing will grow there. Spray a single weed in the middle of a lawn and there will be a hole there for a couple of years.





"Broadleaf only" (like "turfbuilder") herbicides work well on some types not so good on others, you also need to keep them far away from plants you want as I have seen the effects downwind of where any has landed..
Reply:RoundUp will work on creeping charlie if it's not in the lawn. It does not persist in the soil as it breakes down under ultraviolet light %26amp; soil microbes. If creeping charlie is in your lawn then use a broadleaf herbicide. Anything with 2,4-D will kill creeping charlie (there is only one kind of creeping charlie), especially if it's in bloom. If using a herbicidal control, always follow the directions on the label. Creeping charlie can be hand pulled and altering your lawn cultural procedures can help prevent further infestations. Here are some articles that discusses the cultural, mechanical and chemical control of creeping charlie:

P.S. There are some people who will advocate the use of Borax. Borax in sufficient quantities to kill creeping charlie damages turf. It's effectiveness is inconsistent, dependent upon your soil type. Borax has it's own set of problems. Borax contains boron, a micronutrient used by plants. In small quantities boron is safe. But just a little too much boron in your soil can render that soil toxic to all plants. Boron does not readily leach through the soil and is a very stable element. These characteristics increase the risk of long term damage to your soil. The risks just do not out weight the benefit of using Borax as a control for creeping charlie.
