How to Plant, Grow, and Care for Chicory: A Complete Gardener’s Guide
Vibrant blooms and flavorful roots bring both color and nutrition to any garden patch.
Chicory (Cichorium intybus) is a resilient, perennial herb widely known for its bright periwinkle blooms and its dual use as both a leafy vegetable and root crop. With a history stretching back to antiquity, this plant is treasured for its culinary applications, health-promoting inulin fiber, and as an ornamental wildflower. Whether you are interested in cultivating it for salads, coffee alternatives, or simply to add an unfussy beauty to your garden, this guide covers the full scope of chicory’s care—from planting seeds to harvesting roots.
What is Chicory?
Chicory is a herbaceous perennial in the Asteraceae family. Native to Europe but now common across North America and many other regions, chicory inhabits roadsides, meadows, and gardens. Traditionally, it is prized for both its flavorful leaves (which can be mildly to deeply bitter depending on type) and its robust root, historically used as a coffee substitute. Its periwinkle or light purple flowers make chicory instantly recognizable during the warm months.
- Botanical Name: Cichorium intybus
- Type: Herbaceous perennial (can act as a biennial when grown as a vegetable)
- Family: Asteraceae (daisy family)
- Flower color: Periwinkle/light purple, daisy-like
- Main uses: Leaves (salads/cooking), roots (roasted as coffee, inulin fiber extraction)
Chicory Plant Characteristics
Chicory starts life as a rosette of deep-green, toothed leaves that resemble those of a dandelion. In its second year (if left unharvested), the plant sends up tall, stiff, hollow flowering stems, sometimes exceeding four feet. These stems exude a characteristic milky sap when cut. Flowers appear from early summer through fall, opening each morning and closing by late afternoon, a trait that explains why chicory blooms often seem to “disappear” come evening.
Types and Varieties of Chicory
There are multiple types of chicory, each bred for different culinary and agricultural purposes. The main categories are:
- Leaf chicory (Salad/Greens): Includes types like radicchio (red leaves), sugarloaf (green leaves), and Belgian endive/witloof (blanched white heads).
- Root chicory: Grown for its fleshy taproot, used as a coffee substitute or prebiotic fiber source.
Popular garden varieties include:
- Radicchio Varieties: ‘Rossa di Treviso’, ‘Rossa di Verona’, ‘Giulio’, ‘Firebird’ (noted for their colorful leaves and tight heads).
- Witloof/Endive Varieties: ‘Daliva’, ‘Flash’, ‘Zoom’ (grown for white, tender chicons after forcing).
How to Plant Chicory
Chicory is simple to plant, but it does best with early preparation and proper timing. Here’s how to give your plants the best start:
When to Plant
- Direct sow seeds 2–3 weeks before last spring frost, or as soon as the soil can be worked.
- Alternatively, start seeds indoors 5–6 weeks before the last frost and transplant outside when seedlings are sturdy and all risk of frost has passed.
Where to Plant
- Sun: Prefers full sun but tolerates partial shade.
- Soil: Fertile, moist but well-draining soil. Amend with compost for best results.
- Soil pH: 5.5 to 7.0 is ideal.
- Temperature: Chicory grows best between 40°F and 70°F.
Planting Technique
- Sow seeds 1/4 inch deep directly into prepared beds.
- Spacing: For roots (witloof), thin or transplant seedlings to 9 inches apart in rows 20 inches apart. For radicchio and leaf types, plant 8 inches apart in rows 12 inches apart.
- Seedlings typically appear within 14–21 days of sowing, depending on soil temperatures.
Chicory Growing Conditions & Care
Chicory is a low-maintenance plant, but paying attention to these care tips can maximize yields and health:
- Weeding: Vigilant weeding is essential, especially during the early stages, to prevent competition for nutrients.
- Watering: Keep soil moist but not soggy. Uniform and frequent irrigation leads to healthy leaves and roots.
- Fertilization: Avoid high nitrogen fertilizers, as excess nitrogen can cause loose heads and reduce root quality.
- Mulching: Mulch helps retain soil moisture and reduce weed growth.
- Deadheading: Remove spent blooms to focus energy on leaf and root production if ornamental flowers are not desired.
Companion Planting
- Chicory grows well alongside other leafy greens, carrots, and root vegetables.
- Avoid planting too close to crops in the same family to reduce risk of common pests.
How to Harvest Chicory
The harvest method depends on the variety and intended use:
- Leaf chicory: Pick outer leaves for a prolonged harvest. For heading types (e.g., radicchio), cut entire heads when they reach full size.
- Root chicory: Harvest in mid to late autumn once roots reach significant size, typically after leaves die back.
- Witloof: After digging roots, store them and “force” them indoors in darkness to produce the tender, white chicons known as Belgian endive.
Post-Harvest Tips
- Store leaves in the refrigerator for up to a week.
- Store roots in a cool, dark place if not using immediately. Roast roots for coffee or blanch for salads.
Culinary and Health Uses of Chicory
Chicory is as versatile in the kitchen as it is in the garden. Here’s how you can enjoy it:
- Salads: Use young leaves for a spicy addition to spring salads or sauté mature leaves to mellow their bitterness.
- Root coffee: Roast cleaned and chopped roots at low temperature until crisp. Grind and brew for a caffeine-free coffee substitute.
- Cooked greens: Chicory is a staple in Mediterranean and southern European cuisine, often boiled or sautéed with garlic and olive oil.
Nutrition and Health Benefits
- Chicory root is extremely high in fiber, with up to 20% fiber by wet weight and up to 90% by dry weight, primarily in the form of inulin, a prebiotic that supports gut health.
- Rich in other fibers such as pectin, cellulose, and hemicellulose, supporting lower cholesterol and balanced blood sugar.
- Contains antioxidants and supports healthy liver function.
- Has anti-inflammatory properties and may help with digestive complaints.
Common Problems and Pests
Chicory is generally a trouble-free plant but can occasionally experience the following issues:
- Aphids: These can gather on stems and undersides of leaves. Use a strong water jet or apply insecticidal soap if needed.
- Slugs and snails: May chew young leaves. Hand-pick or use barriers like crushed eggshells.
- Fungal diseases: Good air circulation and avoiding overhead watering help prevent problems.
- Leaf miners and root maggots: Practice crop rotation and remove affected plants if infestations are severe.
With vigilance and good cultural practices, chicory remains one of the most low-maintenance crops in the home garden.
Propagation of Chicory
Chicory is almost always propagated by seed for both leaf and root types. To collect your own seed, allow several plants to flower and set seed pods. Harvest seed pods when dry and store in a cool, dry place until sowing the following season.
Chicory as a Wildflower and Pollinator Plant
Chicory is as beautiful in the wild as in the garden. Its striking blue flowers are a magnet for bees and other pollinators, making it a valuable addition to wildlife gardens. In meadows or along field edges, chicory provides color from early summer to fall. Consider letting a few plants flower for their ornamental value and beneficial insects.
