Salt water kills weeds because salt (sodium chloride) dehydrates plants by drawing water out of their cells, causing them to wither and die. This desiccation process disrupts the internal balance of the plant, ultimately leading to its demise. To use, simply dissolve salt in water, and apply the solution directly to the weeds, being cautious to avoid surrounding plants, as salt can also negatively impact soil health and nearby desirable vegetation.
