Which two household items have been proven beneficial when added to water to extend the life of cut flowers?

• A. Mouthwash and Lemon Lime Soda
• B. Vinegar and Baking Soda
• C. Milk and Water
• D. Sugar and Salt

Answer: (A)

Maintaining the freshness of cut flowers hinges on water that is both clean and able to provide some nutrients while minimizing bacterial growth. The combination of mouthwash and lemon-lime soda is thought to help because the mouthwash supplies antiseptic compounds that slow the buildup of bacteria in the vase water, which otherwise clogs the stems and reduces water uptake. The lemon-lime soda adds sugar, giving the flowers a quick energy source, and its acidity helps create a water environment that’s less favorable to many bacteria, supporting better water absorption. Other pairings don’t offer the same balance. Vinegar and baking soda would react and alter the water chemistry in unpredictable ways, not providing a reliable boost to vase life. Milk can spoil quickly and promote bacterial growth. Sugar with salt can create osmotic stress and hinder the plant’s ability to take up water.
