What is Radicchio?

Radicchio (Cichorium intybus) is a leafy plant that belongs to the chicory family. It has deep red, bitter leaves that make it a popular ingredient in salads, risottos, and other Italian dishes. Radicchio is like a miniature version of cabbage; its leaves form tightly compacted heads that are crisp and crunchy.

Why Grow Radicchio?

Aside from being delicious, radicchio offers many health benefits. It's low in calories and high in fiber, making it an excellent addition to any weight-loss diet. Additionally, it's rich in vitamins C and K, as well as folate and antioxidants.

Growing radicchio in your own garden is also a fun and satisfying experience. Since radicchio grows best in cool weather, it's a suitable crop for spring and fall gardening. You can even overwinter some varieties for a late wintertime harvest. Furthermore, when you grow your own radicchio, you ensure that it's free from pesticides and chemicals.

We'll dive into the different varieties of radicchio, including their growing conditions and harvesting techniques.

Growing Radicchio

When it comes to growing radicchio, there are several factors to consider, such as the variety, the growing conditions, and the harvesting techniques. Below are some tips to help you grow your best crop of radicchio.

Red Chicory

Red chicory is a popular type of radicchio that has deep red leaves with white veins. It grows best in cooler conditions and is ideal for spring or fall planting. Red chicory prefers well-drained soil with a pH between 6.0 and 7.5. Your garden bed should receive full sun but can tolerate partial shade. Water your radicchio regularly, keeping the soil evenly moist but not excessively wet.

Growing Conditions

Radicchio grows best in areas with cool temperatures, ranging from 50 to 60 degrees Fahrenheit. The plant prefers fertile, loose soil with good drainage. Rich compost or organic matter can be incorporated into the soil to improve its texture and nutrient content. Make sure to plant radicchio in a location with plenty of sunlight exposure to facilitate photosynthesis.

Harvesting Techniques

Radicchio requires at least six weeks of growth before it's ready to harvest. You'll know it's time to harvest when the heads have reached full size, which typically takes 80-90 days. To harvest properly, grip the base of the head and twist it out or use a sharp knife to cut away the stem cleanly. Remove any damaged outer leaves before storing.

Radicchio Varieties

There are three main varieties of radicchio: Castelfranco, Chioggia, and Tardivo. Each offers its unique characteristics that make them suitable for various culinary pursuits.

Castelfranco Radicchio

Castelfranco radicchio is a milder variety that combines both red and green hues. Its delicate flavor makes it perfect for use in salads, even to chew as is. When they are young, the leaves are incredibly tender, and as it matures, the leaves become firmer but not tough. Castelfranco radicchio grows best in mild weather and prefers sandy soil.

Chioggia Radicchio

Chioggia radicchio, named after the Italian town of Chioggia, is more traditional-looking with its vibrant red color and white ribs. It has a stronger taste than Castelfranco and makes an excellent addition to risottos or other hearty Italian dishes. Chioggia radicchio requires a little bit of patience as it can take up to 100 days to reach full maturity.

Tardivo Radicchio

Tardivo radicchio, also known as the Treviso radicchio, is unique due to its elongated shape that curls into compact red and white balls. It has a slightly nutty and bitter flavor, which makes it perfect for roasted dishes. Tardivo radicchio is a latecomer, meaning that it doesn't mature until winter, giving you a different variety of radicchio during the colder months.
