The claim “The best homemade weed killer: no poison (dries everything in 2 hours)” is a popular gardening headline, but it’s usually exaggerated. Some homemade sprays can make weed leaves look dead quickly, especially in warm sunlight, but they often do not kill the roots, so many weeds can grow back.
A commonly used homemade option is:
Vinegar weed spray
Ingredients
- 1 gallon (about 4 liters) white vinegar
- 1–2 tablespoons dish soap (helps the spray stick to leaves)
How to use
- Spray directly onto the leaves of unwanted weeds.
- Apply on a dry, sunny day.
- Avoid spraying plants you want to keep.
Important cautions
- Regular household vinegar may only burn the leaves; stronger weeds may survive.
- Vinegar can harm grass, flowers, and garden plants.
- Adding salt (a common online suggestion) can damage soil and make it harder for future plants to grow.
For longer-lasting weed control, methods like mulching, pulling roots, covering bare soil, and preventing weeds from going to seed are usually more effective than a quick homemade spray.
So: it may dry weeds fast, but no homemade recipe can honestly guarantee that weeds will “never grow again.”
