Saltwater negatively affects plants by dehydrating them. Plants obtain water via their root system through osmosis. This osmosis is facilitated by cells around the hairs of the plant's roots that water passes through very easily. The salt in the soil can actually pull water out of the cells and dehydrate the plant.
