Many schools of thought exist on adding things to water to help plants grow. Plants grow best when they are given fresh water. Adding salt or sugar to water may damage the root system of the plant.


Salt is necessary to every living thing. However, too much salt will kill any living thing, because it can starve an organism of the water it needs. Too much salt around the roots of a plant interferes with the chemical process that allows plants to absorb water, and interferes with the ability of the plant to make food, starving the plant.


Plants make their own sugar, and have not evolved to absorb sugar from an outside source. Adding sugar to plant water can interfere with the osmosis process of a plant, which is what allows the plant to absorb water from the soil. However, adding a pinch of sugar or an aspirin to water for cut flowers will help the capillaries in the stems remain open longer, and the flowers will stay fresh for a longer time.

Plain Water

Plain water is the best thing for plants. Over centuries, plants have adapted to variations in the amount and make up of water, and are equipped for life and growth by absorbing the water through their roots.
