Weeds are a constant battle in every garden, driveway, and landscaped space, stealing sunlight, nutrients, and water from the plants you actually want to grow. Keeping them under control takes the right mix of strategy, consistency, and environmental care. Whether you prefer homemade solutions, reliable store-bought products, or practical tools, there’s always a method that works best for your setup. This guide covers dozens of effective approaches, from natural weed sprays to flame weeding and smothering with cardboard, so you can reclaim your outdoor space safely and efficiently.
Homemade Weed Killers
- Vinegar and Salt Solution
Mix 1 gallon of white vinegar with 1 cup of salt until dissolved, then add 1 tablespoon of dish soap. Pour into a spray bottle and spray directly on weeds. The vinegar burns leaves, salt dehydrates roots, and dish soap helps the solution stick. Apply on sunny, dry days and avoid desirable plants. - Boiling Water
Boil a pot of water and carefully pour it directly on weeds. This kills them instantly by scalding. Works best for small weeds or those between cracks. - Baking Soda Solution
Mix 1 tablespoon of baking soda with 1 quart of water and a drop of dish soap. Spray thoroughly on weeds to raise soil pH and disrupt nutrient absorption. - Corn Gluten Meal
Sprinkle 1–2 pounds evenly over the area and lightly water. This acts as a pre-emergent herbicide, preventing seeds from sprouting. - Salt and Dish Soap Solution
Dissolve 1 cup of salt in 1 gallon of water, add 1 tablespoon of dish soap, and spray on weeds. Salt dries out the plants while soap helps it cling. - Clove Oil Solution
Combine 2 tablespoons of clove oil, 2 cups of water, and 1 teaspoon of dish soap in a spray bottle. Spray directly on leaves; the eugenol in clove oil breaks down plant cells. - Lemon Juice and Salt Solution
Mix 1 cup lemon juice, 1 tablespoon salt, 1 tablespoon dish soap, and 1 quart water. Spray weeds thoroughly; the acidity and salt kill them quickly. - Essential Oils Solution
Add 10 drops each of peppermint and rosemary essential oils to 1 gallon of water. Shake well and spray directly on weeds. These oils break cell walls and deter regrowth. - Garlic and Onion Solution
Blend 1 garlic bulb, 1 onion, and 1 tablespoon of cayenne pepper with 1 quart of water. Strain and add 1 teaspoon of dish soap. Spray on weeds to weaken them through sulfur and capsaicin compounds. - Hydrogen Peroxide Solution
Mix 1 cup of hydrogen peroxide (3%) with 1 quart of water. Spray on leaves to release oxygen that destroys plant cells.
