How should roses be prepared before placing them in an arrangement?

Before placing roses in an arrangement, it is essential to remove the leaves that will be submerged in the water and to cut the stems at an angle. This preparation ensures that the roses can absorb water efficiently, promoting hydration and longevity. When leaves are left on the stems and submerged, they can rot and create bacteria in the water, which can hinder the hydration of the flowers. Cutting the stems at an angle increases the surface area for water absorption and prevents the cut ends from resting flat against the bottom of the vase, which could create an air lock and hinder water uptake. This method optimizes the care for the roses, ensuring they remain vibrant and healthy in the arrangement.
