Looking for a safe, affordable, and effective way to eliminate weeds in your garden without using harsh chemicals? This homemade weed killer uses simple household ingredients to quickly dry out unwanted plants—especially in pathways, driveways, and gravel areas. Follow this guide to learn how to mix, apply, and maximize the power of this natural solution.
Use 1 liter (about 4 cups) of white vinegar with at least 5% acetic acid.
It works by breaking down plant cell walls, causing rapid dehydration.
Add 2 tablespoons of regular salt.
Salt boosts the vinegar’s drying effect, but avoid overusing it to prevent long-term soil damage.
Use 1 tablespoon of biodegradable dish soap.
It helps the solution stick to leaves and enhances the penetration of the active ingredients.
In a large bucket, pour the vinegar.
Add salt and stir until it dissolves completely.
Gently stir in the dish soap to avoid excess foam.
Pour the mixture into a clean garden sprayer.
Seal it tightly and shake lightly before use.
Store in a cool, shaded place.
Spray directly onto the leaves of weeds, making sure to coat them well.
Apply in full sunlight during a dry, warm day—midday is ideal.
Avoid spraying before rainfall or when wind may spread the solution.
Most results become visible within 2 to 6 hours.
Repeat as needed for stubborn weeds.
Pour boiling water on weeds growing between pavement cracks or stone borders.
It destroys the plant’s cells on contact.
Weed removal is easier when the soil is moist.
This is the perfect time to pull deep-rooted weeds cleanly.
Cover infested areas with a tarp for a few weeks.
The lack of sunlight and oxygen will naturally kill weed growth.
Spread bark, wood chips, or straw as mulch on clean soil.
This blocks sunlight and helps prevent new weeds from sprouting.
This mixture is non-selective—it will kill any plant it touches.
Avoid spraying on lawns, vegetable gardens, or near ornamental plants.
Do not use on soil where you plan to plant soon; salt can linger and harm fertility.
Always wear gloves and eye protection when handling the mixture.
Keep children and pets away until the area is completely dry.
This DIY weed killer offers a chemical-free approach to garden maintenance. When used correctly and combined with smart gardening habits like mulching and hand-weeding, it can help you keep your outdoor space looking clean, safe, and environmentally friendly.
