Storage Guidelines

Commercial storage guidance for leafy greens eaten cooked: collards, kale, rape, spinach, mustard and turnip greens. Storage life depends on initial quality, maturity, cultivar and handling; this is not a household shelf-life guarantee.

Greens wilt and decay quickly, so keep them as cold as possible without freezing, at high humidity, and away from ethylene, which speeds yellowing. Source: USDA Agriculture Handbook 66 (rev. 2016).
