• 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.
