Chicory and Radicchio Bianca di Milano Sumero F1 - 9 plants - Orto Mio

Growing Tips

Orto Mio guidelines for the species, to be adapted to the variety, local climate, and cultivation in soil or pots.

Exposure and Temperature

Full sun, tolerating summer partial shade. Optimal growth at 15–20 °C; late radicchio varieties tolerate cold better. Strong temperature fluctuations encourage pre-flowering.

Soil and Transplanting

Fertile and well-draining soil, pH 6–7. Generally 25–35 cm in-row and 40 cm between rows. Leave one-third of the root ball above the soil. The correct timing depends on the variety's cycle and the expected harvest.

Watering

Regular watering in summer, less frequent than for lettuce. Wait for the surface to dry. In autumn, water moderately only if necessary; avoid waterlogging.

Fertilization

Moderate nutrition, without excess nitrogen. For late varieties, prioritize potassium and suspend fertilization one month before harvest.

Care and Harvesting

Weed and protect during cold transplants. Self-closing radicchio is ready when the heart is full and firm. Cycle, possible tying, and forcing should be evaluated for each specific type.

Indicative Producer Data

Values are indicative: the harvest cycle varies with season, climate, and cultivation conditions.
