Which of the following methods helps prevent blockage in floral arrangements?

Re-cutting stems is a crucial practice in floral arrangement that helps prevent blockage in the vascular system of the flowers. When flowers are cut, the ends can become sealed off by air bubbles or debris if not properly maintained. By re-cutting the stems at an angle, you create a fresh surface that can absorb water more efficiently. This process helps to ensure that the flowers can take up water and nutrients effectively, prolonging their life and maintaining their beauty.

In contrast, watering, while essential for maintaining overall hydration, does not address potential blockages that already exist at the cut end of the stems. Arranging focuses more on the aesthetic placement of flowers rather than their health. Wrapping, which may involve techniques for protecting or presenting the arrangement, does not directly contribute to the prevention of blockage in the stem. Therefore, re-cutting is the most effective method of promoting proper water uptake and preventing blockages.
