Homemade Weed Killer: Does It Really Work?

This mixture works best for:

  • Weeds growing between paving stones.
  • Driveway cracks.
  • Gravel paths.
  • Sidewalk edges.

It is not recommended for garden beds where you plan to grow flowers or vegetables because salt can remain in the soil.

Tips for Long-Term Weed Control

For better long-term results:

  • Pull weeds out by the roots.
  • Remove weeds before they produce seeds.
  • Fill cracks with sand or polymeric sand to reduce regrowth.
  • Apply mulch in garden beds to suppress new weeds.

Important Note

No homemade weed killer can guarantee that weeds will never grow again. Many perennial weeds regrow from roots or underground stems. While vinegar-based sprays may control young weeds, they often require repeat applications and are generally less effective on established weeds. Always avoid spraying desirable plants and use salt-based mixtures sparingly to minimise long-term damage to the soil.
