Lots of people love the invasive perennial creeping Charlie, or Glechoma hederacea. They may even refer to it affectionately as ground ivy, and cultivate it enthusiastically. Many others despise the little beast that vines and twines through their beloved lawns, strangling the grass plants. Whether she knew it or not, your grandma had the answer to your problem on her laundry shelf. Good old borax has been used in home remedies for killing weeds since the 1920s. This naturally occurring mineral fights creeping Charlie plants growing in healthy, established lawns. Apply your homemade solution early in the spring or summer during the weed's active growing season.
Put 2½ gallons of warm water into a large bucket on a warm spring day. Add 10 oz. borax to ½ cup hot water. Stir it very well to dissolve as much of the borax as possible. Pour the mixture into the bucket of water. Stir until the borax is completely dissolved.
Pour the mixture into your sprayer. Reapply the solution once around the same time next spring, and again the following year.
Pull or dig up and destroy stray creeping Charlie plants in your lawn as they occasionally occur. Don't add even little bits of it to your compost heap. Clean up all of the plant material. While this won't eliminate the problem, it will go a long way toward total control efforts. Maintain your lawn appropriately to keep it as healthy as possible. Mow and feed regularly.
Hoe infested areas of your gardening site well. Water the area to moisten and loosen the soil. This will make it easier to pull and dig up ground ivy weeds. Repeat as needed.
Weed and edge the borders of your garden regularly. This will help keep creeping Charlie out.
