How to make a super effective homemade herbicide

If you want a simple, effective homemade herbicide (weed killer), there are a few common household mixtures that work well for driveways, sidewalks, and garden paths. These solutions kill weeds mainly by drying out the plant tissue. 🌱

⚠️ Note: Most homemade herbicides are non-selective, meaning they can harm any plant they touch, not just weeds.
