Everything it needs
9 essentials at a glance
Watering
Chicory prefers consistently moist soil, requiring watering every 1-2 weeks depending on rainfall and temperature.
During hot summer months, increase frequency to weekly. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
Chicory thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
It can tolerate partial shade but may not develop as robustly. Ideal placement includes a south-facing garden bed or container that receives ample sunlight throughout the day.
Soil
Chicory prefers well-draining, loamy soil with a pH range of 6.0 to 7.0.
A recommended potting mix includes equal parts of compost, peat moss, and perlite to ensure good drainage and nutrient availability.
Humidity
Chicory benefits from moderate humidity levels, ideally around 40-60%.
To increase humidity, consider misting the leaves or placing a tray of water nearby. Signs of low humidity stress include browning leaf edges and stunted growth.
Temperature
Chicory grows best in temperatures between 60-75°F (15-24°C).
It is hardy in USDA zones 3-10, tolerating light frost but may bolt in extreme heat. Seasonal temperature adjustments should be made to avoid stress during summer months.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10, applying every 4-6 weeks during the growing season.
Signs of nutrient deficiency include yellowing leaves and poor growth, indicating a need for additional nutrients.
Pruning
Pruning is not typically necessary for chicory, but removing any dead or yellowing leaves can promote better air circulation.
Use clean, sharp scissors or pruning shears to trim away unwanted foliage.
Repotting
Chicory is usually grown directly in the ground, but if grown in containers, repot when roots fill the pot or every 1-2 years.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include root growth emerging from drainage holes.
Propagation
Chicory can be propagated from seeds.
Sow seeds directly in the garden in early spring or late summer. Plant seeds 1/4 inch deep and 12 inches apart. Keep the soil moist until germination occurs, which typically takes 7-14 days.
When it's unhappy
Yellow leaves
Why it happens
Often caused by over-watering or nutrient deficiency.
How to fix it
Check soil moisture levels and adjust watering schedule. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Bolting
Why it happens
Occurs when temperatures rise too high or days become too long.
How to fix it
Plant chicory in cooler months or provide partial shade during hot summer days to prevent bolting.
Pests (aphids, slugs)
Why it happens
Common garden pests that can damage leaves.
How to fix it
Inspect plants regularly and use insecticidal soap or neem oil for aphids, and hand-pick slugs or use organic slug bait.
Root rot
Why it happens
Caused by overly saturated soil conditions.
How to fix it
Ensure proper drainage and reduce watering frequency. Remove affected plants to prevent spread.
Stunted growth
Why it happens
Can result from poor soil quality or insufficient light.
How to fix it
Improve soil with organic matter and ensure the plant receives adequate sunlight.
Care through the year
Spring
In spring, sow chicory seeds directly in the garden after the last frost. Keep the soil moist and thin seedlings as they grow to prevent overcrowding.
Summer
During summer, ensure chicory receives adequate water, especially in hot weather. Provide partial shade if temperatures exceed 80°F (27°C) to prevent bolting.
Fall
In fall, harvest chicory leaves before the first frost for best flavor. If growing for roots, allow them to mature until late fall.
Winter
Chicory is hardy and can survive mild winters. Mulch around the base to protect roots from freezing temperatures and consider covering with frost cloth during extreme cold.
Toxicity & Safety
Chicory is generally non-toxic to pets and children. However, excessive consumption may lead to digestive upset. The leaves and roots are edible, while the flowers are safe but not typically consumed.
Good to know
How often should I water my chicory?
