What type of cutting tool is recommended for flowers to avoid pinching the xylem tubes?

Using shears is recommended for cutting flowers to avoid pinching the xylem tubes because they are specifically designed for making clean, precise cuts without crushing stems. The sharp blades of shears allow for a quick and smooth cut, which is essential in preserving the integrity of the xylem, the tissue responsible for water and nutrient transport in plants. When stems are crushed or pinched, it can obstruct the flow of water and lead to wilting or poor hydration of the flowers.

In contrast, other tools like regular scissors, pocket knives, or utility knives may not provide the same level of precision or could inadvertently damage the stems, leading to compromised care for the flowers. Regular scissors may not be sharp enough or designed for the thicker texture of flower stems, while pocket and utility knives might not allow for the controlled, clean cuts that shears can provide. This distinction highlights why shears are the most appropriate tool for this task in floral design.
