What effect does adding a chemical to lower pH in water have on cut flowers?

Adding a chemical to lower pH in water can significantly enhance the longevity and freshness of cut flowers. Many cut flowers benefit from slightly acidic water, as it encourages better hydration and nutrient absorption. When the pH is lowered, it often helps dissolve air bubbles that may form in the stems, which can impede water uptake. By improving water flow to the plant tissues, flowers can remain turgid and vibrant for a longer period, thus staying fresh longer.

In contrast, while altering pH can impact color, fragrance, and photosynthesis, these effects are either less direct or not the primary benefit for cut flowers. The primary concern for maintaining the freshness of cut flowers is ensuring optimal conditions for hydration and nutrient intake, which is achieved through managing the water's pH.
