Claims that a homemade product “burns weeds in 1 day and they never grow again” are usually exaggerated.
Some products can quickly damage the leaves of weeds, but permanently eliminating weeds depends on the type of weed and whether the roots are destroyed.
What can work for weed control:
- Hand-pulling: Most effective when the entire root is removed, especially after rain when the soil is soft.
- Mulch: A 2–4 inch (5–10 cm) layer of mulch helps block sunlight and prevents many weed seeds from sprouting.
- Boiling water: Can kill weeds growing in sidewalk cracks or driveways, but avoid using it near desirable plants.
- Vinegar-based sprays: Household vinegar may damage the leaves of young weeds on sunny days, but it often doesn’t kill the roots of established perennial weeds, so they may regrow.
Be cautious with homemade recipes
Many online recipes include salt. While salt can kill plants, it also:
- Remains in the soil.
- Can prevent future plant growth.
- May damage nearby grass and garden plants.
For that reason, salt is generally not recommended for garden beds or lawns.
The best long-term approach
- Remove weeds before they produce seeds.
- Pull or dig out perennial weeds with their roots.
- Use mulch or ground cover to suppress new weeds.
- Consider targeted herbicides only if appropriate, following the product label carefully.
No homemade remedy is guaranteed to make weeds “never grow again.” Even professional weed control often requires repeated treatment because new seeds can germinate or roots can regrow.
