What should be done to flower stems before placing them in water?

Cutting the stems at an angle is important for enhancing water absorption. This method increases the surface area through which the plant can take up water, preventing the cut end from resting flat on the bottom of a vase or container, which could block water uptake. An angled cut allows for better contact with the water and reduces the likelihood of air bubbles forming in the stem, which can impede water transport.

While soaking flower stems in sugar water, removing leaves, or using warm water may have their purposes, none are as directly effective in ensuring maximum water absorption as cutting the stems at an angle. Sugar water can provide nutrients but may not immediately help with hydration, removing leaves could potentially remove necessary foliage for photosynthesis, and the temperature of the water can vary in its effects depending on the flower species but does not guarantee a better uptake compared to an angled cut.
