Harvesting: Harvest in the morning once heads begin to become firm. Remove the large, floppy outer leaves to reach the inner, compact head. Cut at the base of the head, leaving some leaf ends, rather than cutting at ground level; another head may be produced. Cut heads may be dunked in cold water and drained to remove "field heat", prolonging storage. Cut radicchio can overwinter to produce another head the next spring (cold areas should mulch plants).
