How to Sow and Plant
+
Sow radicchio seeds indoors from June to September in seed trays or small pots filled with moist, well-draining soil. Keep the soil consistently damp and place containers in a bright location but out of direct sunlight. For outdoor sowing, plant seeds directly in prepared soil beds from May to August, spacing them about 20 cm apart. Cover seeds lightly with soil and water gently to settle. Thin seedlings when they reach a few centimeters tall to ensure healthy development. This method supports successful germination and establishes a strong foundation for vibrant red chicory growth.
Radicchio thrives in well-drained soil with consistent moisture, benefiting from regular watering without waterlogging.

Protect from strong winds and pests like slugs by maintaining good garden hygiene. Harvest leaves when they reach a deep red hue, typically from autumn through early winter, for the best taste and texture. This variety’s robust nature makes it a rewarding addition to any cool-season garden.
