Creeping Charlie is a highly invasive lawn weed. It spreads through your lawn by sending out runners that root into the ground. Like most other lawn weeds, it can be controlled through the use of herbicides along with other lawn care practices. The appropriate time to spray creeping Charlie is either in the spring or early fall when the plant is actively growing. Spraying herbicide in the summer won't have much effect on the creeping Charlie, and may even harm or kill your lawn.
Attach a herbicide concentrate bottle to your garden hose. The herbicide should contain the active ingredients 2,4-D and dicamba.
Turn the water on at the spigot and turn the herbicide bottle's control knob to the "on" position.
Spray the herbicide over your entire yard using a back-and-forth sweeping action. Spray until all the foliage is wet.
Turn the control knob on the herbicide off and turn the water off at the spigot. Disconnect the bottle from the garden hose and store if any herbicide is left in the bottle.
Repeat the application in two weeks if the creeping Charlie has not fully died off.
Mow your grass at a height of 2 1/2 to 3 inches every four to seven days. The higher mowing height will prevent creeping Charlie from thriving within your lawn.
