Description

'Flash F1' Witloof chicory is an early-maturing, productive hybrid variety. The firm heads can be forced outdoors in the vegetable garden or in a cellar. Delicious eaten raw in salads or braised. Sow from May to June and harvest 5 months later.

Witloof chicory (Cichorium intybus foliosum) is a herbaceous plant that belongs to the Asteraceae family. It is commonly named chicon, Belgian endive or endive. However, true endives belong to a closely related species, Cichorium endivia. The most common cultivated forms are escarole and “frisée” (curly) endive.

Witloof differs from other cultivated forms of chicory in that it is grown in three stages: first it sown outdoors in spring; in Autumn, the plants are lifted, the leaves are trimmed off and the roots are stored in sand; they are finally forced in a cool, dark place until firm, tight heads form and are ready to be harvested (approximately 3 weeks later).

Although this may seem like a tedious crop to grow, it is very rewarding! The beautiful white heads have a distinctive bitter taste that is delicious eaten both raw and cooked. They are fabulous chopped up in a salad with walnuts, blue cheese and a drizzle of honey dressing. In France, chicory heads are traditionally baked whole in bechamel sauce. Witloof has numerous health benefits, including boosting the immune system, easing digestion and reducing inflammation.

Harvesting: roots are lifted in October-November and stored in sand until forcing. For longer harvests, forcing can be staggered.

Storage: witloof chicory stores well in a cool, dark place. It is often sold wrapped in blue paper to protect the blanched leaves from the light.

Good to know: hoeing and weeding around your plants regularly will help keep the weeds in check. Mulching is a great way to keep the soil moist, especially during dry spells.

NB: This variety is marked F1 for "F1 hybrid" meaning that its qualities are derived from carefully selected parent plants. This results in a variety that is both full of flavour and resistant to diseases. Sometimes criticised or wrongly assimilated to GMOs, F1 hybrid seeds have the advantage of producing reliable, uniform, disease-resistant plants. Unfortunately, these qualities will not be passed on to following generations.

Planting and care

Sowing:

In May, sow lightly in shallow flat-bottomed drills, about 5 cm wide and 2 cm deep. Leave 30 cm between each row. Cover the seeds lightly and water. Germination takes about 8 days. Thin out the seedlings, keeping one every 15 cm. If necessary, they can be transplanted when the seedlings reach the 7-8 leaf stage.

Care:

To avoid diseases such as downy mildew or leaf spot, weed and hoe around your plants regularly and make sure to rotate your crops every 3 to 4 years. Mulching is a great way to keep the soil moist, especially during dry spells.

Forcing:

In October-November, lift the witloof plants. Keep only those with roots that measure over 4 cm in diameter. Trim off the leaves about 1 cm above the collar (the base of the leaves). Place the prepared roots in a sand-filled container in a sheltered place until they are ready for forcing. For harvests all winter long, force the plants in batches every fortnight. Place the roots side by side in forcing trays filled with sand. Keep away from the light. Room temperature needs to be around 8 to 10°C (a cellar is ideal). It is also possible to force the plants outdoors. Choose a sheltered spot and dig a trench about 1,20 m wide and 25 cm deep. Place the roots in the trench and cover with 10 cm of potting compost followed by 10 cm of compost. Cover with a layer of straw and plastic sheeting. The heads are ready to be harvested about 4 weeks later, when they are roughly 15 cm long.
