Floral preservatives primarily serve to lower the water pH and extend the vase life of cut flowers. When flowers are harvested, they begin to deteriorate, and one of the factors that contribute to this process is the quality of the water they are placed in. By lowering the water pH, floral preservatives create a more favorable environment for the flowers to take up water and nutrients. This helps to reduce the growth of bacteria and fungi that can clog the stems, allowing flowers to remain hydrated and healthy for a longer period. Additionally, the nutrients in floral preservatives can provide essential elements that support the flowers’ metabolism, further contributing to their longevity.

The other options focus on aspects that are not the primary function of floral preservatives. For instance, enhancing color may be a result of proper care but isn’t a direct purpose of preservatives. While keeping flowers looking fresh in stores is a benefit, it is not the primary reason these products are used. Reducing the weight of the arrangement is unrelated to floral preservatives, as these products do not affect the physical weight of the flowers.
