285 views

Boiling water is typically more effective than vinegar for killing weeds. Boiling water will scorch and kill the plant on contact, including the roots, preventing regrowth. In contrast, while vinegar can kill the leaves, its effect on the roots is limited, which can allow the weed to regrow. For tough, perennial weeds, using boiling water could be a more sustainable and practical option.

FAQs & Answers

  1. Why is boiling water more effective than vinegar for killing weeds? Boiling water kills weeds by scorching the entire plant, including roots, preventing regrowth, while vinegar primarily affects only the leaves.
  2. Can boiling water be used safely around all plants? Boiling water is effective but non-selective, so it should be applied carefully to avoid harming desirable plants nearby.
  3. Are there drawbacks to using vinegar as a weed killer? Vinegar may not kill weed roots effectively, leading to possible regrowth and requiring multiple applications.
