Some common substances that can be used to arrest decay of cut flower stems are a floral preservative solution, a mix of sugar and bleach, or simply fresh water that is changed daily.

Adding 7-Up to the water in a vase of cut flowers is said to prolong the life of cut flowers. The lemon/lime juice in 7-Up lowers the pH level in the water, and cut flowers like a lower pH. Next, the sugar in 7-Up provides a food source for the cut flowers.
