Radicchio Rossa Di Verona [Cichorium intybus var. foliosum]

The radicchio 'Rossa di Verona' is an ancient two-year-old traditional leafy vegetable from the eponymous city of Verona in northern Italy. The leafy vegetable was mainly grown until 1985, until newer varieties were bred to withstand colder temperatures. Radicchio grows erect in rosettes and has deep red and heart-shaped leaves that wind around each other, forming a tight, round to highly oval head. The taste is sharp and slightly bitter, which decreases when heated. Small rosettes can be harvested early. Radicchio is only partially hardy, the rosette-forming species can stay in the bed over the winter and sprout again in spring and is then one of the first fresh leafy vegetables in the garden. A variety for winter cultivation in the subtropical climate zone and in the temperate climate zone with winter protection.

Subtropic climate (Mediterranean) (e. g. B. Portugal, Spain, Italy)
Sow directly into the open from March to May or in autumn from August to October. We recommend pre-cultivation in small bowls from January to May or in autumn from August to October.

Moderate climate (e. g. B. Germany, Switzerland, Poland)
Sow directly into the open air from the end of May. We recommend warm pre-cultivation in small bowls from April to June.

General
During germination does not tolerate cold temperatures below 15 °C. For a long harvest period, harvest 1/4 of the leaves from the outside to the inside, taking care not to damage the heart to keep growth stable. We always recommend pre-cultivation at Radicchio. D Azum let the seedlings grow in a small bowl to the first visible radicchio leaves, then pik into the desired container. After pecking, let the seedlings grow at warm temperatures above 20 ° C until they are planted out as seedlings. The planting of the seedlings in the bed is carried out from the 2nd Pair of leaves after the cotyledders.
Radicchio-p Flances prefer a sunny location with a moist, humus-rich and slightly loamy soil. Avoid waterlogging.

Additional tips
The typical red color of the leaves only arises when exposed to cold. In order to quickly obtain a fine, crumbly and well-drained soil, an additional incorporation of biochar and primeval rock flour is recommended.

Type of propagation
Spread occurs via seeds.

Care Plants
We recommend winter protection at temperatures below-3 °C. A loosened soil and planting in mixed culture is sufficient.

Germination ability of seeds: 2-4 years
