Sticker burrs are an annual grassy weed, often found in lawns, fields and parks. Also known as grass burrs and sand burrs, these weeds produce sharp,, spiky burrs that attach themselves to anything they touch. The burrs can be painful to step on and are difficult to remove from clothing, hair and animal fur. Killing the weed is the best way to prevent it from spreading and taking over your lawn.
Pull the weeds up by hand. Wear gardening gloves to protect your hands as you grasp the weed at the base of the plant and pull up. Discard the weeds in the garbage, or burn the weeds in a fire pit to prevent the seeds from spreading.
Place a barrier around the plant. Cut off the bottom and top portions of a 2-liter plastic soda bottle and place it over the plant to prevent any weed killers you apply from spreading to the rest of your garden or lawn.
Apply baking soda at the base of the sticker burr plant. The sodium in the baking soda draws moisture out of the plant and dehydrates it. Apply the baking soda at least once a week until the plant dies.
Sprinkle salt on the leaves and base of the plant. The salt adds an even stronger dose of sodium to the soil and dehydrates it.
Pour undiluted bleach on the plant. A few days after applying the bleach, pull the plant out of the ground. The bleach in the soil prevents the plant from growing back.
Sprinkle borax powder on the base of the plant. Borax powder supplies the weed with an excessive amount of boron, a natural plant micro nutrient, that damages and kills the weed.
Pour undiluted white or apple cider vinegar on the plant. Vinegar contains acetic acid, which draws moisture from the plant and dehydrates it until it dies.
Mix 1 oz. of vodka, two drops of liquid soap and 2 cups of water. Pour the mixture on the leaves of the plant when the sun is at its highest point in the day. When the sunlight shines on the alcohol, it breaks down the waxy covering on the leaves and dehydrates the plant.
Pour boiling water on the plant. The boiling water kills the plant quickly without leaving behind any chemicals in the soil.
