What is the recommended water temperature for keeping cut flowers in optimal condition?

Keeping cut flowers in optimal condition is greatly influenced by water temperature, and warm water is generally recommended for several reasons. Warm water facilitates better absorption by the stems, as it allows for improved hydration. When flowers are first placed in water, warm temperatures help to dissolve air bubbles that may have formed in the stem, allowing for a more efficient uptake of the essential nutrients and moisture. This leads to longer-lasting freshness and vitality in the flowers.

In contrast, cold water can slow down the absorption process and may not effectively help flowers that have already experienced dehydration during transportation or handling. Room temperature water might work in some cases, but it does not promote the same level of hydration efficiency as warm water. Boiling water is not suitable as it can cause significant damage to the flower stems and lead to wilting or even stem tissue death, preventing the cut flowers from thriving. Thus, warm water is the ideal choice for maintaining the freshness and health of cut flowers.
