Salt (sodium chloride) works to kill weeds by dehydrating the plants and disrupting the internal water balance of the plant's cells. Since salt is water-soluble, it is most effectively applied when mixed with water as this makes it easier for the weeds to absorb. Sodium chloride is highly toxic to all plants, which is why caution must be taken ...
