What is the recommended humidity level for flowers stored in the refrigerator?

The recommended humidity level for flowers stored in the refrigerator is 90%. Maintaining a high humidity level is crucial for preserving the freshness and quality of floral arrangements. Flowers contain a significant amount of water, and when stored in low humidity, they can quickly lose moisture, which leads to wilting and a decrease in overall health.

At 90% humidity, the environment helps to keep the flowers hydrated, prolonging their lifespan and maintaining their appearance. This is particularly important because flowers continue to respire, a process where they take in oxygen and release carbon dioxide, even when stored. High humidity minimizes the risk of dehydration, allowing flowers to remain vibrant and lively.

In contrast, lower humidity levels can lead to air dryness, reducing water uptake through the stems, which is detrimental to the condition of the flowers. Thus, the humidity level plays a vital role in floricultural practices, especially when it comes to storage.
