A lot of “homemade weed killer” recipes online claim to kill weeds in a couple of hours, but the results depend on the plant, weather, and where it’s growing. A common non-commercial approach is a vinegar-based spray, which can dry out the leaves quickly, especially on small, young weeds.
Simple homemade weed spray
Ingredients
- 1 liter (about 4 cups) white vinegar
- 1 tablespoon dish soap (helps the spray stick to leaves)
How to use
- Mix the ingredients in a spray bottle.
- Spray directly onto the weed leaves on a dry, sunny day.
- Avoid soaking nearby plants you want to keep—the spray can damage them too.
- Give it time; tough weeds may need repeat treatment.
Important notes:
- It works mainly by burning the foliage; deep-rooted weeds may grow back.
- Avoid spraying near lawns, flowers, vegetables, or desirable plants.
- Using salt as a “permanent weed killer” can harm soil and make areas difficult to grow in later.
For the best long-term weed control, removing roots, adding mulch, or improving ground cover usually works better than any spray alone.
