If your lawn has been taken over by creeping Charlie you can kill it naturally. There is no need to purchase commercial herbicides, unless of course you wish to do so. Creeping Charlie is a low-growing, yellow flowered weed that takes over your lawn. Borax will kill those pesky weeds, leaving your lawn free of creeping Charlie. Borax only works for creeping Charlie and will not kill other weeds, such as dandelions. It is best to treat your lawn with Borax in late spring or early summer. This is the time of year when weeds actively grow.
How you make your own creeping Charlie weed killer? You only need three items to create your homemade creeping Charlie weed killer. Take into account that using Borax may discolor your lawn -creating a yellow color-for a few weeks. Mow the lawn frequently and within a few weeks your lawn should be back to its normal color.
5 teaspoons of Borax, for every 25 sq. feet of lawn you are treating
1 quart water
Pump spray bottle.
So how do I use this to kill creeping Charlie on my lawn?
Mix Borax in water. Measure the ingredients accurately as too much may kill your grass but too little wont’ kill creeping Charlie.
Spray to over the 25-sq foot area on your lawn with your spray bottle.
Water and fertilize your lawn-with a fertilizer of your choice-after you have treated the area as this rapidly fills in the space on the lawn left by the dead weeds.
If you wish to try another method consider using Coca-Cola as a weed killer as well. Pour Coca-Cola in the center of weeds during a hot summer day and watch it go to work removing those weeds from your lawn. The weeds will “roast.” Take into account that using Coca-Cola may take up to week for the weeds to completely die.
