Which statement best describes the role of acidifiers in flower food?

• A. Increase pH
• B. Lower pH levels
• C. Neutral pH
• D. No effect on pH

Answer: (B)

Acidifiers in flower food are used to create a mildly acidic environment in the vase water. Lowering the pH helps nutrients stay more soluble and readily available to the stems, and it slows down or suppresses many bacteria that can grow in the water and clog the stems’ water-conducting vessels. With the water less prone to bacterial buildup, flowers can drink more effectively and stay hydrated longer, which is why the role is described as lowering pH. Increasing pH would make the water less favorable for uptake and could promote more bacterial growth; a neutral or no-effect approach wouldn’t deliver these benefits.
