Yes, weeds can be killed with salt water, but use it cautiously. The sodium in salt water dehydrates plants, causing them to die. However, salt can also harm the soil quality and nearby plants. To target weeds without widespread damage, apply salt water directly to the weeds' leaves and avoid the soil. For a more controlled application, mix 1 part salt to 8 parts water and apply using a spray bottle. Remember, this method should be used sparingly to prevent soil salinity from becoming too high.
