What is the primary advantage of a slanted cut on a flower stem?

The primary advantage of making a slanted cut on a flower stem is that it prevents stem blockage. When a flower stem is cut at an angle, a larger surface area is exposed, which allows for better water absorption. This is crucial for the health of the flower, as it ensures that it receives sufficient hydration. A straight cut can lead to the stem resting flat against the bottom of a vase, potentially blocking the flow of water and air. By preventing this blockage, the slanted cut helps maintain the longevity and freshness of the flower arrangement.

Other options, while they might have some relevance to flower care, do not capture the most critical reason for this method of cutting. The aesthetic aspect of the slanted cut may enhance the overall design, but it is not the primary reason for performing the cut. Similarly, it does not significantly affect the height of the flower or the weight of the stem. Instead, the focus is on ensuring optimal water uptake to keep the flowers healthy for as long as possible.
