Storage Guidelines

Commercial storage guidance for water convolvulus (water spinach, kang kong, ung choi; Ipomoea aquatica). Storage life depends on initial quality, maturity, cultivar and handling; this is not a household shelf-life guarantee.

Chilling injury (darkened, wilted leaves and stems and more bacterial rot) is the main disorder, so display it cool with misting and never on or under ice. Source: USDA Agriculture Handbook 66 (rev. 2016).
