What is the primary function of floral preservatives?

The primary function of floral preservatives is to extend the vase life of cut flowers, and this is achieved by lowering the water pH. Floral preservatives typically contain a blend of ingredients, including sugars for nourishment, acids to lower the pH, and biocides to inhibit bacterial growth. Lowering the pH of the water helps improve water uptake, ensuring that the flowers remain hydrated and healthy for a longer period. This prolongs their visual appeal and vitality in arrangements.

While preventing wilting is a benefit of floral preservatives, it is a direct consequence of their primary function, which is to extend vase life through improved hydration and nutrition. Options that suggest enhancing scent or coloring flowers do not reflect the essential role that these preservatives play in floral care.
