Final answer:
In floral design, pulsing is a technique used to prolong the lifespan of cut flowers by hydrating them and maximizing their longevity.
Step-by-step explanation:
In floral design, the term pulsing refers to a technique used to prolong the lifespan of cut flowers. It involves placing the stems of freshly cut flowers in warm water for a certain period of time before arranging them in a floral display. Pulsing helps to hydrate the flowers, open their blooms, and maximize their longevity.
When flowers are freshly cut, they undergo a process called transpiration, where they lose water through their stems and petals. Pulsing in warm water helps to reverse this process by allowing the flowers to absorb water and nutrients, replenishing their moisture levels. This helps the flowers stay hydrated, remain fresh, and last longer in a floral arrangement.
