If you’re looking for a homemade herbicide, keep in mind that many DIY weed killers are non-selective, meaning they can damage or kill desirable plants too. They may work on small weeds, but they usually won’t replace commercial herbicides for deep-rooted or invasive weeds.
A simple homemade option:
Vinegar-based weed spray (for cracks and unwanted areas)
Ingredients
- 1 liter (about 4 cups) white vinegar
- 1–2 teaspoons dish soap (helps the mixture stick to leaves)
How to use
- Mix the ingredients in a spray bottle.
- Apply directly to weed leaves on a dry, sunny day.
- Avoid spraying nearby grass, flowers, vegetables, or other plants you want to keep.
- Repeat if needed, since many weeds can regrow from their roots.
Tips for better weed control
- Pull or dig out weeds after the soil is damp to remove roots.
- Add mulch around garden plants to block sunlight and reduce new growth.
- For weeds growing between paving stones, careful spot treatment is usually more practical than spraying large areas.
Avoid risky DIY mixtures
Recipes involving strong acids, large amounts of salt, or other harsh substances can damage soil, harm nearby plants, and create longer-term garden problems.
If you tell me where the weeds are growing (lawn, driveway cracks, vegetable garden, flower beds) and what type of weed they are, I can suggest the safest approach.
