What type of flower processing involves placing stem ends in water and cutting them underwater?

The method referred to in the question, which involves placing stem ends in water and cutting them underwater, is often recognized as underwater cutting processing. This technique is particularly beneficial for maintaining hydration in the stems of the flowers. By cutting the stems underwater, air bubbles are prevented from entering the vascular system of the plant, which can impede water uptake. This method is vital in extending the life of cut flowers and ensuring they remain fresh for as long as possible.

Utilizing this cutting technique can significantly enhance the longevity of the flowers in arrangements, making it an essential process for florists. It highlights the importance of proper hydration techniques in flower care and processing, which is crucial for maintaining flower quality in retail and arrangement settings.
