Characteristics and varieties of red chicory

Red chicory is distinguished by presenting compact buds, intense red or purple color and white veinsIt belongs to the Asteraceae family and is especially appreciated in countries like Italy, where it has various designations of origin.

There are also other types of chicory like escarole (Bread of sugar), Belgian endive and chicory root, which are also grown for their leaves or roots, although they differ in appearance and culinary uses.

Soil requirements and site preparation

For optimal development of red chicory, it is essential to pay attention to the quality of the soil. This vegetable prefers deep, loose, fresh, and well-drained soilsA substrate rich in organic matter and with a slightly acidic pH (above 5) promotes proper bud formation and enhances their intense coloration.

Before starting sowing, it is advisable to:

• Tilling the land in depth to remove stones and roots, loosening the soil to avoid waterlogging.
• Provide organic matter as mature compost or worm humus, improving the structure and fertility of the substrate.
• In professional farms, calcium superphosphate and ammonium sulfate amendments can be used in quantities measured according to the size of the plot.

It is important to avoid sandy or clayey soils in excess, since they hinder moisture retention or promote compaction respectively.

Ideal climate and location for cultivation

Red chicory adapts well to temperate climates, although it tolerates low temperatures, being resistant even to mild frosts. It can withstand moderate winds and some exposure to cold, making it a viable option for those who want to enjoy their garden for much of the year.

With regards to location:

• Prefer sunny places, but can grow in semi-shade.
• In areas with Mediterranean climate or temperate, it can be grown almost all year round by establishing staggered sowing cycles to ensure continuous harvests.
• In colder areas, it is advisable to plan for protected or greenhouse planting to avoid damage from severe frost.

Sowing red chicory: methods and calendars

La sowing red chicory It can be done in two main ways: directly in the ground or through seedbedEach method has its advantages and adapts to the conditions of each garden. It's important to consider the area's climate and the variety chosen to determine the appropriate planting time.

Sowing in seedbed

• Ideal for obtaining more uniform plants and facilitate transplanting, especially in cold climates or to advance the cycle.
• The ideal germination temperature It is situated between 20 and 25°C.
• It is recommended to sow the seeds in trays with universal substrate, maintaining constant humidity but without flooding.
• Once the plants have developed 4-5 true leaves and reached 6-8 cm in height, they can be transplanted to their final soil with a separation of 30-40 cm between them.

Direct sowing

• Direct sowing is less laborious and adapts well to extensive crops.
• It is generally carried out on ridges or furrows separated from each other by 30 to 60 cm, placing the seeds about 20-30 cm apart in the furrow.
• After sowing, it is essential to impregnate the substrate with light watering.
• La Germination usually occurs in 5 to 10 days depending on temperature and humidity.

Recommended planting times

• Temperate or Mediterranean climate: It can be sown from March to late autumn, with staggered harvests.
• Early varieties such as early Treviso or Chioggia can be sown in late winter or early spring.
• Late varieties: It is recommended to sow in summer to harvest in autumn and winter.

Planting density and timing will vary depending on the variety and local climate, but a typical distance between plants is 30x30 cm to ensure the development of compact and healthy buds.

Care during cultivation

Although red chicory is a resistant and easy cultivation to manage, requires certain care during its development to avoid problems and obtain a quality harvest.

Irrigation

• Keep the earth always slightly moist, avoiding puddles that can damage the roots or cause diseases.
• irrigation should be regular, especially during active plant growth and during hot periods.
• An irrigation system by drip It is ideal for controlling humidity and avoiding overwetting the foliage.
• Mulching with straw or plant materials helps to retain moisture and reduce evaporation.

Weeding and tillage

• Eliminates weeds that compete for water and nutrients.
• Work gently to avoid damaging the surface roots of the chicory.
• A couple of light tillage operations during the cycle are sufficient in most cases.

Whitening the leaves

In some varieties of radicchio, especially in the late Treviso, the technique of tying or covering the leaves to whiten the heart and soften the bitter taste. This consists of:

• Gather the outer leaves and tie them gently when the bud begins to form.
• Keep them like this for 2-3 weeks before harvesting.
• This technique protects the heart from direct sunlight and makes the inner leaves more tender and less bitter.

Recommended partnerships and rotations

Red chicory combines well with other garden crops, which facilitates its integration into mixed cropping systems and rotations to avoid pest problems and soil depletion.

• Good associations: lettuce, beans, broccoli, cabbage, kale, and cauliflower.
• Avoid associating with other Asteraceae to prevent the accumulation of common pests.
• Rotation is essential. Don't grow chicory in the same field for more than three or four consecutive years.

Harvesting red chicory

The red chicory harvest It depends on both the variety and the planting season. Usually, the buds will be ready to harvest between 8 and 14 weeks after sowing when they reach a height of 12 to 15 cm or the desired size and compactness.

• Use a sharp knife to cut the bud at ground level.
• If you want to use the plant for successive leaf cuttings, cut only the outer leaves and allow the heart to sprout.
• The roots, in the case of root chicory, are generally harvested in the fall by carefully digging up the plants.
• Harvesting can be staggered if there is variability in plant development.

It is recommended do not delay the harvest once the bud has reached its optimum point, since excessive time in the field can increase the hardness and bitterness of the leaves.

Conservation and storage

After harvesting, red chicory can be stored in a cool, shady place for several days. To prolong its preservation:

• Keep the buds clean and dry.
• Wrap in slightly damp kitchen paper and store in the refrigerator if not going to be consumed immediately.
• Leaves and roots intended for drying should be placed in ventilated and shaded places to avoid loss of color and flavor.

• Black donut and caterpillars: They cause foliar damage, especially in loose-leaf varieties.
• Beetles and wireworms: Less frequent but possible in soils with high organic matter.

Diseases

• Mildew (bremia lactucae): It appears in humid climates, causing yellow spots on leaves. Promoting ventilation reduces the risk.
• Botrytis (gray rot): It attacks mainly when there is excess humidity.
• Sclerotinia: Causes rot at the base and stems, eliminate affected plants and rotate crops to prevent spread.
• Chicory rust (Puccinia chicorii): Sporadic, generates yellow spots on the leaf blade.
• Premature flowering: In cases of abnormal temperatures or transplants at inappropriate times. Respecting the growing cycles minimizes the risk.

Tip: Keep the soil clean, ventilate the crop if it is under cover, and rotate species to reduce the incidence of pests and diseases.
