How to Grow Chicory
Cichorium intybus
Chicory is a hardy cool-season vegetable that grows in most soils with full sun or light shade. Sow direct from late spring and thin to 20 cm apart; it needs little feeding but benefits from consistent moisture. The key tip is blanching — covering the hearts for 10–14 days before harvest dramatically reduces bitterness and produces the mild, tender leaves chicory is prized for.

Care Essentials
- Apply a balanced fertiliser at sowing or planting. A mid-season liquid feed encourages strong heart formation but avoid over-feeding which promotes loose, bitter heads.
- Blanching the centre of mature plants for 10–14 days before harvest reduces bitterness significantly. Cover with a plate, pot, or dark fleece to exclude all light from the developing inner leaves.

Pests & Diseases
Pest Aphids
Identification: Colonies of grey or green aphids cluster on young shoots and leaf undersides, causing distorted growth and sticky honeydew.
- Remove by hand or spray with a strong jet of water.
- Insecticidal soap for heavy infestations.
Pest Slugs and Snails
Identification: Irregular holes rasped in leaves, especially on young transplants and during wet weather.
- Use copper tape barriers or beer traps.
- Apply organic slug pellets around the base of plants.
- Ferric phosphate pellets.
Pest Leaf Miners
Identification: Pale winding trails between leaf surfaces made by larvae of leaf-mining flies.
- Remove and destroy affected leaves.
- Cover plants with fine mesh netting to prevent egg-laying.
- No effective chemical control available to home gardeners.
Disease Downy Mildew Bremia lactucae
Symptoms: Yellow patches on upper leaf surfaces with a white-grey downy coating beneath.
Treatment: Remove affected leaves promptly.
Prevention: Improve air circulation and avoid overhead watering.
Disease Crown Rot Sclerotinia spp.
Symptoms: Base of the plant collapses; encouraged by wet, poorly drained soils.
Treatment: Remove and destroy affected plants.
Prevention: Ensure good drainage, avoid overwatering, and rotate chicory with unrelated crops each year.
