If you’re looking for a homemade weed killer without commercial herbicides, a common DIY option is a vinegar-based spray. However, claims that it will “dry everything in 2 hours” are usually exaggerated—results depend on the weed type, weather, sunlight, and the strength of the mixture.
Simple homemade weed spray
Ingredients
- 1 gallon (about 3.8 L) white vinegar (higher-strength horticultural vinegar works faster than household vinegar)
- 1–2 tablespoons dish soap (helps the liquid stick to leaves)
How to use
- Mix the vinegar and dish soap in a spray bottle or garden sprayer.
- Spray directly onto weed leaves on a dry, sunny day.
- Avoid spraying nearby grass, flowers, vegetables, or desirable plants—vinegar is not selective and can damage them too.
- Reapply if weeds regrow, especially deep-rooted weeds.
Important notes
- Vinegar mainly burns the leaves; many perennial weeds may grow back because the roots remain alive.
- Salt is sometimes added to homemade weed killers, but it can damage soil and prevent future plant growth, so it’s best avoided in gardens or planted areas.
- For long-term weed control, methods like mulching, hand removal, and improving soil coverage are often more effective.
If you tell me where the weeds are (lawn, driveway cracks, patio, vegetable garden, etc.), I can suggest the safest option for that area.
