Boiling water is an effective remedy against many weeds.

Common weeds like crabgrass and dandelions are a familiar but unwelcome sight in many lawns. To keep weeds at bay, homeowners can opt to use herbicides, but such toxic treatments can do more harm than good if not used properly. Instead, there are effective home treatments to keep the weeds at bay, sparing exposure to chemicals and the expense to buy them.

    • 1

      Pour or spray vinegar on invasive weeds. Spray directly on the weed and away from desirable plants.

    • 2

      Sprinkle rock salt on weeds growing in sidewalk cracks or a driveway. Avoid applying to any other area, because it will kill any living plant.

    • 3

      Boil water and quickly pour onto weeds, once a day for up to three days. Wait for the weeds to wilt and then die. Use a roto-tiller or hand pull roots of existing weeds. Repeat this process every four days until weeds are gone.

    • 4

      Mix 1 tsp. of rubbing alcohol with 1 liter of water in a spray bottle. Apply liberally to weeds, but keep away from other plants.

    • 5

      Spread 20 lbs. of corn gluten meal to every 1,000 square feet of lawn in April and again in August. Use the natural herbicide as a pre-emergent treatment against crab grass seeds.

    • 6

      Practice effective lawn management to minimize weed and crabgrass growth. Use a 1-inch layer of mulch in flower beds or cover the planting area with a barrier such as a tarp, newspaper or plastic sheet to prevent weeds from taking root in the soil.
