Yes, you can sprinkle rock salt to kill weeds, but use it sparingly. Rock salt is effective because it dehydrates plants and disrupts their internal water balance. However, it's not selective and can harm desired plants nearby. For a targeted approach, mix rock salt with water (about 1 part salt to 3 parts water) and apply it directly to the weeds you wish to eliminate. Be cautious when using near other plants and avoid overuse as it can lead to soil salinity, making the area barren and unfit for future planting.
