How can I effectively use boiling water and vinegar to kill weeds in my garden?

To effectively use boiling water and vinegar to kill weeds in your garden, simply boil water and mix it with vinegar in a 1:1 ratio. Carefully pour the mixture directly onto the weeds, making sure to cover the entire plant. The heat from the boiling water will kill the weeds, while the vinegar will help prevent regrowth. Be cautious when handling boiling water and vinegar to avoid burns.
