How should stems be cut to effectively absorb water?

Cutting stems on a slant is the most effective method for allowing them to absorb water. This angled cut increases the surface area of the stem that is exposed to water, which helps in maximizing water uptake. When stems are cut at an angle, a larger area is open to the water flow, as opposed to a flat cut or straight cut which can make contact with the bottom of a vase and hinder the flow of water due to potential blockage.

Additionally, cutting stems on a slant is beneficial for preventing air from entering the stem. Air bubbles can form and block the vascular system, which can lead to wilting and reduced longevity of the flowers. The angled cut helps prevent the entrance of air and allows smooth water entry.

Other cutting methods, such as cutting straight across or in a circular motion, do not provide the necessary surface area or may introduce air pockets that interfere with water absorption. Therefore, the slanted cut is the preferred technique for ensuring that stems can effectively draw water, ensuring that the flowers remain hydrated and vibrant for a longer period.
