Storage Guidelines

Commercial storage guidance for dry bulb onions, default (HB66's main dry-onion recommendation, stated for pungent types). Storage life depends on initial quality, maturity, cultivar and handling; this is not a household shelf-life guarantee.

High humidity induces rooting and warmth induces sprouting, and together they increase rot, so bulbs must be well dried and cured, kept cold and moderately dry, and protected from condensation. Highest freezing point: -0.8°C. Source: USDA Agriculture Handbook 66 (rev. 2016).
