Radicchio is one of the most iconic crops in Italian horticulture, appreciated for its intense flavor, crisp texture, and outstanding versatility in the kitchen. Thanks to its adaptability and the wide range of available types, it is an ideal crop for both professional growers and home gardeners. To achieve uniform, high-quality production, it is essential to choose the most suitable variety, carefully plan the sowing period, and follow a few simple agronomic practices.
When to sow radicchio?
Planning the sowing schedule is one of the most important aspects of successful radicchio cultivation. In particular, the summer period is considered strategic for planning autumn and winter production. Proper planning allows growers to:
- achieve staggered harvests;
- improve head uniformity and quality;
- optimize crop yields;
- meet different market demands.
How to prepare the soil
Before sowing, it is advisable to prepare the soil thoroughly by eliminating waterlogging and promoting healthy root development. A well-prepared soil structure ensures more uniform plant growth and encourages the formation of compact, high-quality heads.
