Repeated applications of Round Up. Try to keep the overspray onto your real lawn to a minimum.

Where do you live and what kind of grass do you have?

The active ingredient triclopyr is effective at selectively removing creeping charlie from turf. Spray it late spring and early fall. Will probably take a couple years to remove it all.

Make sure that you do the below steps on a sunny day without rain in the next 24hr forecast.

1) Mow the lawn to create open cuts in the Creeping Charlie that will allow it to absorb herbicides.

2) Dissolve 10 oz. Twenty Mule Team Borax in 4 oz. of warm water (You can find Twenty Mule Team Borax in the laundry aisle of your grocery store). Dilute in 2.5 gallons of water to cover 1000 sq feet. Spot spray the mixture using a fine mist spray bottle. Try to keep from spraying the desirable turfgrass as much as possible as the borax will harm it a bit as well but should recover (Creeping Charlie is more susceptible to borax though).

3) Wait an hour or two until the borax has dried on the Creeping Charlie. Now spray Weed B Gon (or anything that contains 2,4D).

It will take 2-3 weeks for the Creeping Charlie to turn brown. If you still have some Creeping Charlie left after 3 weeks, you can follow up with another dose of the borax.

Last fall, I applied Weed-B-Gone purple label. Some of the Evil Charlie died over the mild winter, but about half survived. I had an amount of Crossbow herbacide, which I had been using on Crossbow is a blend of 2,4-D and triclopyr. I accidently mixed it at twice the recommended dosage, and while it killed Evil Charlie, it also took out the grass. Another batch, mixed at the recommended seems to have caused Charlie a slow death without killing the grass., we'll see. This was done during the time Charlie was sending out spring flowers. I'm thinking of mixing my own, using 2,4-D, triclopyr and quinclorac (Drive), and wonder if anyone has recommended doses. This fall, I'll hit the stragglers with the Weed-B-Gone purple again a couple of times to make it miserable over the winter. Has anyone done this kind of treatment and had success?

I said to use Round Up???? As recently as May????

I should have said Weed-b-Gon Chickweed, Clover, and Oxalis Killer (purple label). In other words, triclopyr as joneboy suggested right after me above and bill g wisconsin 14 hours ago.

10-20 ounces of borax per 1,000 square feet could possibly sterilize the soil forever. Boron is a tricky chemical. A little bit of it is needed, but there's a very sudden threshold beyond which it becomes deadly.
