Which term names the chemical mixture that extends vase life by lowering the water pH?

• A. Hydrating Solution
• B. Processing Flowers
• C. Transpiration
• D. Floral Preservative

Answer: (D)

Lowering the water pH to extend vase life is about using a floral preservative, a chemical mix designed to create a healthier, longer-lasting environment for cut flowers. This preservative typically combines sugar for energy, a biocide to reduce bacterial growth, and an acidifying agent to keep the water slightly acidic. The lower pH slows down bacterial clogging of the stem’s vessels and improves water uptake, helping the flowers stay hydrated longer and degrade more slowly. That combination—energy source, antimicrobial, and acidifier—is what the term floral preservative refers to. The other options don’t capture this purpose: a hydrating solution isn’t a standard term for this mix, processing flowers refers to handling steps, and transpiration is the plant’s water loss process.
