  1. If you're wanting to remove an area of grass or strips to reseed your lawn or create a border or raised beds in areas of your lawn for growing vegetables or flowers, the best way to remove the creeping charlie/grass combo while keeping your beneficial soil microbes alive and happy is to dig up the first few inches and remove. If you're wanting to keep the grass but remove the creeping charlie, here is a link to a question answered earlier today that gives you several options.

    As for your raised beds, it's best to start with a clean slate, so to speak, by removing the grass. However, you can place landscape fabric or several layers of wet newspapers (2 to 4 inches thick) on top of the grass. Then place your soil on top of the landscape fabric or newspapers and fill in the beds. This will smother the grass and keep it from coming up through the soil. Good luck!

  2. The best way of ridding your lawn from this menace is to grow a healthy lawn; mow high and mow often; water deeply to encourage deeply and healthier roots (Creeping Charlie is shallow-rooted and easily starves in a thick, healthy lawn); and aerating and dethatching your lawn will also help. You can also smother larger patches with black plastic or a thick layer of mulch and then reseed the area with grass seeds once the creeping charlie is gone. Best control for spotty areas is to dig up the plant by its roots. Some gardeners have had success by treating the lawn with borax; about a 10 ounce box mixed with 1/2 cup warm water and then diluted into 2 1/2 gallons of water.

    Another option is to apply spot applications of a non-toxic weed killer. These ready-to-use products control weeds in various ways; herbicidal soaps combine fatty acids and salts; more potent vinegar-based products such as Burnout have a higher concentration of acetic acid (20 percent as opposed to household vinegar, which is 5 percent); and some products use essential oils, such as clove oil (eugenol), cinnamon oil, or citrus oil (d-limonene). Avenger is a weed killer that uses d-limonene, and Weed Zap uses a combination of clove oil and cinnamon oil. Products such as these are available at online garden supply retailers and at various garden centers or home improvement stores. These products are non-selective, which means they kill by contact on any plant on which they are sprayed. Good luck!
