What role does temperature play in keeping cut flowers fresh?

The role of temperature in preserving the freshness of cut flowers is significant, particularly regarding the metabolic processes of the flowers. Lower temperatures help to slow down the flower's metabolic rate, which in turn reduces the rate of respiration and the consumption of stored energy. This is crucial because as flowers respire, they use nutrients that are essential for maintaining their vitality and longevity.

When cut flowers are kept at cooler temperatures, they are better able to retain their hydration and structural integrity, which contributes to a longer lifespan. This cooling effect also helps to delay wilting and extending the period during which the flowers remain visually appealing.

Conversely, warm temperatures can accelerate respiration rates and lead to quicker deterioration of the flowers. While warmer conditions may initially promote bloom opening, excessive heat generally harms the overall longevity of the cut flowers. Recognizing this relationship allows for better care and handling of floral arrangements, ultimately leading to more successful displays.
