What is a key factor in determining the longevity of fresh cut flowers?

Water quality is indeed a key factor in determining the longevity of fresh cut flowers. Fresh cut flowers need clean, nutrient-rich water to stay hydrated and healthy throughout their lifespan. Poor water quality, which may contain contaminants or insufficient nutrients, can lead to bacterial growth, clogging the stems and reducing the flowers' ability to absorb moisture. This, in turn, can accelerate wilting and shorten the lifespan of the blooms.

While the type of flower can influence how long certain varieties last, it is not as universally critical as water quality across all species. Similarly, temperature during transport can affect flowers, but once they are placed in a vase, the water's quality becomes paramount. Soil type does play a role in the health of the plant before it is cut but is less relevant to the longevity of cut flowers after they have been harvested. Thus, maintaining high water quality is vital to extend the life of fresh cut flowers effectively.
