Creeping Charlie or ground ivy, Best way to kill it is when you see the flowers on it. Use weed control with a litte dawn. If you spray it any other time your just wasting your time.
Yeah you need to spray those weeds there just reseeding if you don't kill them and let the new seed have a chance. I've read about CC to spray in spring and I 've read about spraying it in the fall it is one tuff weed to kill.
