This weed can be selectively controlled with a broadleaf herbicide containing 2,4-D, such as Weed-B-Gon. I would wait until the fall (October) to make your herbicide applications. In the summer months when temperatures are greater than 85 degrees herbicide activity is minimal and herbicide vitalization is substantial.
