What function do preservatives serve in floral designs?

Preservatives play a crucial role in extending the lifespan of fresh flowers in floral arrangements. They typically contain a combination of ingredients such as sugars, biocides, and acids that work together to provide nutrients to the flowers, inhibit bacterial growth, and maintain optimal pH levels in the water. This combination helps to keep the flowers hydrated and healthy, thereby preventing premature wilting and decay. By employing preservatives, florists can enhance the beauty and longevity of their arrangements, making them more visually appealing for a longer period.
