What is the purpose of using a flower preservative?

The purpose of using a flower preservative is primarily to extend the life of cut flowers by providing essential nutrients and inhibiting the growth of bacteria. When flowers are cut, they are deprived of their source of nutrients from the soil, and they can quickly begin to wilt and decay. Flower preservatives typically contain a blend of sugar, acid, and biocides, which work together to nourish the flowers while also preventing microbial growth in the water. The sugar serves as a food source, the acid helps to maintain an appropriate pH level for optimal water absorption, and the biocides work to reduce the presence of bacteria that can clog the stems.

In contrast, options that suggest changing flower colors, enhancing fragrance, or diluting sap do not address the fundamental needs of cut flowers. The goal of a flower preservative is not to alter their appearance or scent but to ensure they remain vibrant and healthy for as long as possible.
