Planting Radicchio

Direct-seed about 4 to 6 weeks before average last frost in well drained, rich, moisture-retentive soil. (Non-forcing varieties can be sown through mid-summer for fall and winter harvest.) Plant seeds 1/2 inch deep, 3 to 4 inches apart, in rows 24 inches apart. Thin seedlings to a 10-inch spacing.

Growing Radicchio

Mulch to retain moisture and suppress weeds. Apply an organic liquid plant food when heads begin to form.

Harvesting and Storing Radicchio

In early winter, plants can be lifted and grown indoors during winter. A few outside leaves can be harvested for eating without harming seed production. Radicchio can be cut as soon as the head is a useful size; at maturity the heads will be firm but not hard (about 4 to 6 inches in diameter). Pick when head is mature but not old; older ones are tougher and bitter. To store, place in a plastic bag in the refrigerator.

Radicchio Insect and Disease Information

Radicchio is bothered by few insects or diseases; good soil and adequate moisture are important. Cover the seedbed with floating row covers to deter flea beetles.
