What is the optimal temperature range for storing fresh-cut flowers and foliage?

The optimal temperature range for storing fresh-cut flowers and foliage is typically between 33°F and 38°F. This cooler range slows down the metabolism of the flowers, helping to preserve their quality, extend their vase life, and maintain their vibrant colors. Storing flowers at these temperatures reduces respiration rates and delays senescence, which is critical for maintaining freshness and minimizing the potential for premature wilting.

In contrast, temperatures that are too cold, such as those found in the 25°F to 30°F range, may cause chilling injury to many sensitive flower varieties, leading to damage and deterioration. Similarly, higher temperatures, such as those in the 40°F to 45°F or 50°F to 55°F ranges, can accelerate flower aging and limit their overall longevity due to increased respiratory activity and water loss. Therefore, maintaining the recommended storage temperature is essential for optimal preservation of fresh-cut flowers and foliage.
