How is the underwater cutting processing method performed?

The underwater cutting processing method is performed by cutting stems underwater to avoid air entry. This technique is essential in floral arrangement and flower care as it prevents air bubbles from forming in the stem's vascular system, which can impede water uptake. When stems are cut above water, air can enter the vascular system, leading to blooms wilting and reducing their lifespan. Therefore, cutting stems underwater ensures that the cut opens directly into water, allowing for immediate hydration and helping the flowers to remain fresh longer. This method is particularly important for flowers that are sensitive to air exposure and for those that are highly absorbent.
