Planting & Care

Sow Bianco Avorio Cardoon seeds indoors 6-8 weeks before the last frost, or directly outdoors after the danger of frost has passed. Plant seeds about 1/4 inch deep in a seed-starting mix, keeping the soil consistently moist but not waterlogged. Germination typically occurs in 10-20 days at temperatures around 65-75°F. Once seedlings have developed several true leaves and the weather has warmed, harden them off and transplant to the garden, spacing plants 24-36 inches apart.

Cardoons prefer full sun and well-drained soil rich in organic matter. Water regularly during dry spells, but avoid overwatering. To blanch stalks for a more tender, milder flavor, tie the outer leaves together and mound soil around the base a few weeks before harvest. Harvest stalks when they are about 1-2 inches thick, typically in late summer or fall. In colder zones, apply a thick layer of mulch to protect crowns over winter, or grow as an annual.
