What Kills Creeping Charlie?
Creeping Charlie (Glechoma hederacea) is a rapidly spreading vine that is also commonly referred to as Creeping Jenny or ground ivy. During the spring, this ivy produces a plethora of lavender-colored flowers. As it spreads, it can cause damage by crowding surrounding plants and taking all the nutrients from the soil. This pesky member of the mint family can be controlled with a variety of chemical products. Does this Spark an idea?

Identification
-
Creeping Charlie is a spreading vine that features long, square stems. At every node in the stem, a root system forms, anchoring the vine to the ground. The leaves are round in shape and bright green in color. When it is in bloom, this member of the mint family produces purple or blue funnel-shaped flowers.
2,4-D and MCPP
-
Herbicides containing MCPP, 2-D and 4-D, applied to an entire lawn, can help prevent the growth and spread of Creeping Charlie. This product should be applied per manufacturer instructions and sprayed in the fall.
-
Borax
-
Borax (sodium tetraborate) is another chemical option for controlling Creeping Charlie. Borax is effective because it contains toxic levels of boron. As the boron sets on the plant, the foliage turns yellow and eventually features brown spots. As the boron continues to penetrate the plant, the stems of the vine die, killing the whole plant. Care must be taken when applying borax to a lawn because, while correct application can kill Creeping Charlie, over-application can also kill the surrounding healthy grass and other plants in the yard or garden. This product should be applied per manufacturer instructions to prevent damage to the lawn.
Broadleaf Weed Killer
-
Another option for control of Creeping Charlie, broadleaf weed killers, contain salt of dicamba, combined with 2,4-D and MCPP -- a combination that kills Creeping Charlie. These products are available at garden supply centers and should always be applied per manufacturer instructions, as they contain chemicals that are potentially harmful to other plants, humans and pets if misused.
