Water from different sources was compared in regard to optimizing the postharvest performance of cut gladiolus flowers. Tap water from different flower markets was compared with distilled, deionized, canal, and carbonated water to find the best water type to be used by the industry in regards to postharvest longevity and water relations of cut gladiolus. Carbonated water proved to be the best water for handling cut gladiolus as it not only extended longevity, but also maintained relative fresh weight, and continued water uptake by the cut stems. Deionized water and distilled water were better than tap water from different regional flower markets. The canal water and tap water from Pattoki were the worst water types due to their higher heavy metals and salt levels; therefore, the growers and florists should avoid using these water types for handling their cut flowers. In summary, cut gladiolus should be placed in carbonated water for its effective control on bacterial proliferation and lower pH. Additionally, tap water should be analyzed before using for cut flower handling.
