The claim “The best homemade weed killer: no poison (dries everything in 2 hours)” is misleading.
Many homemade weed killers use ingredients like:
- White vinegar
- Table salt
- Dish soap
These mixtures can make weeds wilt quickly, especially in hot, sunny weather, but there are important limitations:
- Vinegar burns the leaves it touches but usually doesn’t kill the roots of established perennial weeds, so they often grow back.
- Salt can damage the soil and make it difficult for desirable plants to grow for a long time. It’s generally not recommended for garden beds.
- Dish soap helps the solution stick to leaves but isn’t an herbicide by itself.
The “dries everything in 2 hours” part usually refers to visible wilting of the leaves, not permanent control of the weed.
For the best results:
- Pull weeds by hand when the soil is moist.
- Use mulch to prevent new weeds from sprouting.
- For cracks in driveways or patios, a vinegar-based spray may provide temporary control, but repeated applications are often needed.
If you’re looking for a homemade option, a common recipe is:
- 1 gallon (3.8 L) white vinegar (5% acetic acid)
- 1 tablespoon dish soap
Avoid adding salt unless you’re treating an area where you never want plants to grow, such as between paving stones, because it can persist in the soil.
If you tell me where the weeds are (lawn, vegetable garden, flower bed, gravel driveway, or sidewalk cracks), I can suggest the most effective and least damaging method.
