When lawn weeds detract from the beauty of your yard, chemical intervention may be necessary. If the offender is ground ivy (Glecoma hederacea), sometimes called creeping charlie, the household cleaner Borax provides a natural home remedy. Borax contains boron, a naturally-occurring plant nutrient required for proper plant growth. However, even slight amounts of excess boron are toxic to some plants. Many common lawns weed don't respond to Borax, but ground ivy, hardy in U.S. Department of Agriculture plant hardiness zones 3 through 10, does.
Fill a plastic bucket with 2 1/2 gallons of warm water. Warm water dissolves Borax powder faster and more thoroughly than cold water. This will create a enough solution to treat a 1,000-square-foot area of lawn.
Mix 8 ounces, or approximately 2 cups, of Borax with 4 ounces of warm water. Mix thoroughly, then pour the mixture into the bucket of water and stir the diluted solution. Wear gloves and safety goggles as you work.
Mix the solution with a spoon or other implement until the Borax powder completely dissolves in the bucket of water. Pour the Borax-water solution into a landscaping sprayer. It can be a handheld device or the larger version that you wear on your back. Keep the solution mixed well.
Spray the solution evenly across 1,000 square feet of lawn. If your yard is smaller, reduce the amount of solution made up front. Spraying smaller areas at higher levels of boron can damage turf grasses and prevent any new plants from growing. Spraying larger areas lightly will be ineffective.
Treat small areas of lawn by dissolving 5 teaspoons of Borax in 1 quart of water. Mix the products well. Apply the solution evenly over 25 square feet of ground-ivy affected lawn.
