Endive is usually not stored but can be held for up to three weeks in the refrigerator. Gather the leaves together and tie them with a rubber band. Put the tied head in a plastic bag and place it in the refrigerator.
Endive can also be stored like celery, upright, close together, with moist sand around the roots and the outer leaves tied around the heads. It will last in very moist, 32 degree conditions like this for two to three weeks.
