Radicchio Overview and Planting Information
Radicchio, a vibrant perennial plant belonging to the Asteraceae family, is commonly grown as an annual in USDA zones 4-10. Whether you choose to plant it in spring or fall, understanding the plant’s specific needs and characteristics is key to successful cultivation.
With a plant height ranging from 4 to 6 inches, radicchio requires low to moderate maintenance, making it an excellent addition to any low-maintenance garden. Its unique maroon, pink, and creamy yellow leaves add a distinctive charm to both your garden and your plate.
In terms of soil preference, radicchio thrives in well-drained, slightly acidic soil. Spacing is crucial for optimum growth, and the plants should be placed 8 to 10 inches apart to allow for proper air circulation and root development. This ensures that each radicchio plant has sufficient space to flourish and reach its full potential.
When it comes to watering, radicchio has low to moderate needs. Providing about 1 inch of water per week is typically sufficient to keep the plants healthy and thriving. However, be mindful of not overwatering, as excessive moisture can lead to root rot.
Radicchio thrives in full sun to partial shade conditions during the summer months. Ideally, it should receive at least 6 hours of direct sunlight daily. However, partial shade can also be suitable, especially in regions with intense summer heat.
The time it takes for radicchio to reach maturity depends on the variety you choose. It typically ranges from 50 to 100 days. During this cultivation journey, you’ll witness the gradual transformation of seedlings into fully formed heads of radicchio.

Planting Radicchio
To ensure optimal growth, it’s crucial to consider the soil temperature. Radicchio thrives when the soil temperature ranges between 40°F and 70°F. Here are two methods for planting radicchio:
- Direct Sowing: If starting from seeds, sow them directly into the ground. Space the seeds about 1 inch apart and lightly cover them with soil.

Late summer and early fall are the best times to plant radicchio for optimal flavors. The cool weather during these periods allows the vegetable to develop its distinctive taste.
When transplanting the seedlings to the garden, make sure to dig shallow holes and place the seedlings in them. Thoroughly water the seedlings to help them establish roots in their new environment.
Growing Radicchio
Once planted, radicchio requires proper care and maintenance to ensure healthy growth. Here are some tips to help you grow radicchio successfully:
- Provide well-drained soil: Radicchio prefers loose, well-drained soil. Improve soil structure by adding compost or well-rotted manure before planting.
- Consistent watering: Radicchio has moderate water needs. Water the plants regularly but avoid overwatering, as excessive moisture can lead to root rot.
- Proper spacing: Ensure adequate spacing between plants, with 8-10 inches between each seedling. This allows them to grow without crowding and promotes good air circulation.
- Weed control: Keep the radicchio bed weed-free to minimize competition for nutrients and water.
- Monitor pests and diseases: Watch out for common pests like slugs, snails, and aphids. Treat any infestations promptly to prevent damage to the plants.

To force radicchio, you’ll need to follow these steps:
- Dig up the entire plant, including the taproots. It’s important to ensure that you preserve the entire plant to encourage the second round of growth.
- Cut off the heads at the base. Make a clean cut to remove the heads from the rest of the plant.
- Prune the roots. Trim any excess or damaged roots to promote healthy growth in the forcing container.
- Replant in a pot of peat moss or water. Choose a suitable container and provide a nutritious medium for the radicchio to grow in. Peat moss and water are commonly used options.
- Shield the forcing container from light. This can be achieved by using a dark cover or placing the container in a dark area. This process is crucial for blanching the radicchio and achieving its delicate tender texture.
- Wait for 15 to 25 days. With proper care and light restriction, new tender blanched radicchio sprouts will emerge.
