Planting & Care

Sow 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 well-draining seed-starting mix. Keep the soil consistently moist but not waterlogged. Germination typically occurs in 10-20 days at temperatures around 65-75°F (18-24°C). Once seedlings have developed a few true leaves, harden them off gradually before transplanting to the garden.

Cardoon prefers full sun and rich, well-drained soil. Water regularly during the first growing season to help establish a deep root system. Mature plants are quite drought-tolerant. To blanch stalks for a milder flavor, tie the leaves together and mound soil around the base a few weeks before harvest. In colder zones, apply a thick layer of mulch in winter to protect the crowns.
