How should flowers be cut for optimal hydration?

Cutting flowers at an angle, under water, is the best practice for optimal hydration. When the stems are cut at an angle, it increases the surface area for water absorption. This angle allows for a larger opening through which the stem can draw water more effectively.

Performing this cut under water helps to prevent air bubbles from entering the stem. Air bubbles can block the vascular system of the plant, hindering its ability to absorb water. By cutting under water, the cut end of the stem remains submerged, reducing the chance of introducing air into the stem immediately after cutting.

Other cutting methods may not provide the same benefits. A straight cut can reduce the surface area for water intake, while cutting at a point does not enhance water absorption significantly. Using a knife above water risks trapping air in the stem, which can lead to wilting and dehydration. Thus, the combination of cutting at an angle while submerged is the most effective method for ensuring flowers remain hydrated and healthy.
