Will adding salt to your outdoor pond hurt the plants?

Salt is harmful to pond plants and should not be added to your outdoor pond. Salt can cause dehydration and nutrient deficiencies in plants and can stunt their growth or even kill them. In addition, salt can alter the water chemistry of the pond, making it less hospitable to beneficial bacteria and aquatic life. If you need to add salt to your pond for any reason, do so in moderation and be sure to monitor the water quality and the health of your plants.
