That claim is almost certainly exaggerated.
If someone says “THIS burns weeds in 1 day! They NEVER grow again,” it’s usually clickbait. Here’s what to know:
- Many homemade weed killers (such as vinegar, salt, or boiling water) can burn the visible leaves within a day, making weeds look dead.
- However, many weeds regrow from their roots or seeds, especially perennial weeds.
- There is no universal treatment that guarantees weeds “never grow again” after a single application.
For long-term weed control:
- Pull weeds with as much of the root system as possible.
- Apply mulch to block new weeds from germinating.
- Use an appropriate herbicide if needed, following the label directions and considering nearby plants and environmental impacts.
- Remove weeds before they produce seeds to reduce future growth.
If you saw a video claiming a specific ingredient or product works permanently, tell me what it was (or share the video or recipe), and I can explain how effective it actually is.
