About Chicory
Chicory is a member of the Asteraceae family and has been cultivated for centuries across continents for its edible leaves, buds, and roots. Its deep taproot and drought resilience make it a hardy fixture in wild and cultivated settings. Not only does it flourish in disturbed, sunny areas, but its flowers paint landscapes with a gentle purple hue in the summer. Chicory’s culinary uses include salads, roasted chicory root for coffee, and as a nutritious, bitter green in dishes worldwide.
If left untended, chicory can self-seed prolifically. Gardeners value its resilience and its ability to thrive in conditions where other vegetables struggle.

Chicory Varieties
Chicory has several varieties, which differ in their culinary uses and growth habits. Two primary types cultivated in gardens are witloof (Belgian endive) and radicchio:
- Witloof: Grown for its roots, which are forced indoors to produce white chicons. Notable varieties include Daliva, Flash, and Zoom.
- Radicchio: Cultivated for its head of leaves, offering vivid colors and distinctive bitter flavors. Popular varieties include Rossa di Treviso, Rossa di Verona, Giulio, and Firebird.
- Wild Chicory: Found in meadows and roadsides, with loose leafy growth and a more pronounced bitterness.
Choosing a mix of varieties creates visual interest in gardens and adds complexity to salads and dishes.
Growing Requirements
Soil
- Well-drained and fertile: Chicory prefers deep, nutrient-rich soils which favor root and leaf development.
- Maintain soil pH between 5.5 and 7.0.
- Loosen soil before planting to accommodate the long taproot.
Sunlight
- Full sun: Chicory thrives in direct sunlight, but can also tolerate partial shade.
Temperature and Humidity
- Cool-weather crop: Best grown between 45°F and 75°F (7°C–24°C).
- Warmer temperatures encourage bolting, especially when grown for leaves. However, bolting is less problematic if growing for roots or flowers.
- Chicory tolerates frost, making it possible to overwinter in some climates.
Planting Chicory
When to Plant
- Spring: Best time for sowing chicory seeds outdoors. For autumn or winter harvest, sow seeds in mid-summer.
How to Plant
- Sow seeds 1/4 inch deep in rows spaced 20 inches apart for witloof; 12 inches apart for radicchio.
- Thin seedlings to 8–9 inches apart, depending on variety.
- Mix compost into the soil before planting to improve fertility.
- Avoid excessive nitrogen, which can cause loose heads in radicchio and poor root formation in witloof.
Seed Propagation
Chicory is easily propagated by seed, although root divisions are also effective. Seeds are heavier than those of dandelion and do not travel far in the wind, primarily spreading where animals or humans disturb the soil.
Transplanting
- Start seeds indoors 4–6 weeks before last frost date for earlier harvest.
- Transplant seedlings outdoors once they are large enough to handle and the risk of heavy frost has passed.
Care and Maintenance
Watering
- Frequent and uniform watering: Essential for healthy greens and roots.
- Avoid waterlogged conditions; chicory prefers moisture but dislikes saturated soils.
- Mulching helps retain moisture and suppress weeds.
Weed Control
- Regular weeding is crucial, especially for seedlings.
- Mulch around plants to reduce weed competition and conserve moisture.
Fertilizing
- Incorporate balanced, nitrogen-based fertilizer at planting for leaf production.
- Excess nitrogen may harm root development and leaf compactness.
Pruning and Maintenance
- Remove faded flowers to encourage further blooming.
- If growing in lawns, regular mowing keeps stems low but chicory may persist due to its taproot.
Pest and Disease Management
Chicory is relatively pest-resistant but faces threats from slugs and snails. These pests favor moist, sheltered environments and leave irregular holes, shredded leaves, or slime trails on the plants.
Managing Slugs and Snails
- Clean up debris and weeds to reduce shelter for pests.
- Apply wood ashes or crushed eggshells around plants to deter slugs and snails.
- Set out lettuce or grapefruit skins to attract pests away from chicory.
- Bury dishes filled with beer at soil level to trap and drown pests.
If infestations are severe, leaves may become shredded. Timely action helps preserve crop quality.
Disease Control
- Chicory generally resists major diseases. Maintaining air circulation and keeping foliage dry minimizes fungal problems.
- Crop rotation and planting in open locations further reduce risk.
Weed Chicory Management
- Hand removal: Dig out entire taproot to prevent regrowth if chicory is unwanted.
- Selective broadleaf herbicides can control large infestations in lawns, though may require repeat applications to completely kill roots.
- Maintain healthy, dense lawn by proper mowing, watering, and fertilization to suppress chicory establishment.
Harvest and Storage
Harvesting Leaves and Roots
- Harvest greens throughout the growing season, selecting young, tender leaves for salads.
- For witloof, dig roots in late autumn. Store roots in sand, then force them in dark, cool conditions to produce chicons (blanched shoots) over several weeks.
- Radicchio heads can be harvested once they reach full size; firm heads deliver best flavor and texture.
Harvest Times
| Type | Harvest Time | Notes |
|---|---|---|
| Witloof | 3-5 weeks after forcing | Blanched chicons are mild, crunchy |
| Radicchio | As heads mature | Firm heads deliver best quality |
| Leaf chicory | Young stages | Tender, less bitter |
Storage
- Harvested greens store in the refrigerator for several days.
- Chicory roots can be kept in cool, dry sand for several months prior to forcing.
- Blanched chicons should be eaten fresh for best taste and texture.
Uses of Chicory
Culinary Uses
- Salads: Young leaves and radicchio heads are flavorful and add color.
- Cooking: Leaves retain some bitterness when cooked. Often paired with rich flavors or in Italian cuisine.
- Chicory root: Roasted and ground as a coffee substitute or additive.
- Chicons: Blanched shoots from witloof roots, prized for their crunch and mild flavor.
Ornamental and Ecological Uses
- Pollinator support: Chicory flowers attract a variety of bees and butterflies.
- Deep taproots help break up compacted soil and improve drainage in garden beds.
Frequently Asked Questions (FAQs)
Q: Is chicory easy to grow?
A: Yes, chicory is resilient and adapts well to varied soil and climate conditions, making it suitable for both beginners and experienced gardeners.
Q: Why does chicory sometimes bolt in summer?
A: Chicory bolts, or sends up flowering stalks, in response to heat, especially when grown for its leaves. Bolting is less of a concern if growing for roots or ornamental flowers.
Q: What is the difference between witloof and radicchio?
A: Witloof is grown mainly for its roots, which yield blanched chicons when forced in darkness. Radicchio is a leafy chicory, producing tight reddish heads eaten fresh or cooked.
Q: How do you force chicory roots?
A: After digging witloof roots in autumn, store them in moist sand in darkness. Allow 3–5 weeks for chicons to develop, then harvest for salads and cooking.
Q: Are there any pests I should watch for?
A: Slugs and snails are the main pests. Maintain clean, dry beds and use organic deterrents like eggshells and beer traps to protect young plants.
Conclusion
Chicory’s unique blend of grassy greens, crunchy roots, and dazzling flowers makes it a valuable and versatile plant—in both kitchen and garden. With proper planning, care, and harvest, any gardener can enjoy the joys chicory brings, whether for culinary experimentation or simply its wild, perennial blooms. Following the guidance above ensures successful chicory cultivation and a bountiful, beautiful addition to your plot.
