Chicory grows best when planted after the last frost has passed. Knowing exactly When To Plant Chicory is key to getting a strong, healthy crop that will provide leaves for salads or roots for coffee substitutes. This guide walks you through everything you need to know, from soil temperature to regional timing.
Chicory is a cool-season crop. It does not like extreme heat or deep freezes. If you plant too early, a late frost can kill young seedlings. If you plant too late, the summer heat will make the leaves bitter and tough. The sweet spot is a few weeks after your area’s last average frost date.
When To Plant Chicory By Season
Spring Planting
Spring is the most common time to sow chicory. Wait until the soil temperature is at least 45°F (7°C). For most regions, this is 2 to 4 weeks after the last frost. In colder climates, this might be mid-April to early May. In warmer zones, you can plant as early as March.
To check soil temp, use a simple soil thermometer. Stick it 2 inches deep in the morning. If it reads 45°F or higher, you are good to go. If you don’t have a thermometer, watch for dandelions blooming. That is a natural sign that chicory can be planted.
Fall Planting
Fall planting works well in mild climates. Sow seeds 6 to 8 weeks before the first expected fall frost. This gives the plants time to establish before winter. In zones 8 and warmer, you can plant in September or October. The cool fall weather produces sweet, tender leaves.
Fall-planted chicory often overwinters and produces early spring greens. This is a great trick for getting two harvests from one planting. Just make sure the plants have at least 4 to 6 true leaves before the first hard freeze.
When To Plant Chicory By Climate Zone
Cold Climates (Zones 3-5)
In these zones, spring comes late. Plant chicory from late April to early June. Soil warms up slowly, so be patient. You can start seeds indoors 4 weeks before the last frost. Transplant seedlings outside after hardening them off for a week.
Fall planting is risky in cold zones. The growing season is too short. Stick to spring planting for best results. If you try fall planting, use a cold frame or row cover to protect young plants.
Temperate Climates (Zones 6-7)
These zones offer two good planting windows. For spring, plant from mid-March to mid-April. For fall, plant from mid-August to mid-September. The moderate temperatures are ideal for chicory growth.
In these zones, you can also do a succession planting. Sow a small patch every 2 weeks from spring to early fall. This gives you a continuous supply of fresh leaves. Just stop planting 8 weeks before the first fall frost.
Warm Climates (Zones 8-10)
Warm zones have mild winters and hot summers. Plant chicory in late fall or winter for spring harvest. The best time is October through December. Avoid summer planting entirely. The heat will make the plants bolt and taste bitter.
In very hot zones like Florida or Texas, grow chicory as a winter annual. Plant in September or October. Harvest through winter and early spring. The plants will die back when summer heat arrives.
When To Plant Chicory For Different Uses
For Salad Greens
If you want tender leaves for salads, plant in early spring or late summer. Spring planting gives you leaves in 6 to 8 weeks. Fall planting gives you leaves in 8 to 10 weeks. The cooler weather keeps leaves sweet and less bitter.
For baby greens, you can plant densely and harvest when leaves are 4 to 6 inches tall. This takes about 30 to 40 days from seeding. Make successive plantings every 2 weeks for a steady supply.
For Roots (Coffee Substitute)
For large, meaty roots, plant in early spring. Roots need a full growing season to develop. Plant as soon as soil is workable in spring. Harvest in late fall after the first frost. The frost triggers the roots to convert starches to sugars, improving flavor.
Roots take 120 to 150 days to mature. If you plant in late spring, you might not get full-sized roots before winter. Stick to early spring for the best root crop.
For Forage Or Cover Crop
Chicory is often used as a forage crop for livestock or as a cover crop. For forage, plant in early spring or late summer. The deep taproot helps break up compacted soil. For cover cropping, plant 6 to 8 weeks before the first fall frost.
As a cover crop, chicory adds organic matter and improves soil structure. It also attracts beneficial insects with its blue flowers. Plant it in rotation with other crops for best results.
How To Plant Chicory Step By Step
Prepare The Soil
Chicory grows best in well-drained soil with a pH between 6.0 and 7.0. Remove rocks and weeds. Loosen the soil to a depth of 8 to 10 inches. Mix in compost or aged manure for nutrients. Avoid fresh manure, which can burn young roots.
If your soil is heavy clay, add sand or perlite to improve drainage. Chicory roots can rot in waterlogged soil. Raised beds work well for heavy soils.
Sow The Seeds
Chicory seeds are tiny. Sow them shallowly, about 1/4 inch deep. Space seeds 1 inch apart in rows 12 to 18 inches apart. Cover lightly with soil and water gently. Keep the soil moist until seeds germinate, which takes 7 to 14 days.
For a continuous harvest, sow a new row every 2 weeks. This works best in spring and fall. In summer, skip planting due to heat stress.
Thin The Seedlings
When seedlings are 2 to 3 inches tall, thin them. For leaf production, space plants 6 to 8 inches apart. For root production, space them 10 to 12 inches apart. Crowded plants produce small leaves and thin roots.
Use scissors to snip off extra seedlings at soil level. Pulling them can disturb the roots of nearby plants. You can eat the thinned seedlings as microgreens.
Water And Mulch
Chicory needs consistent moisture, especially in the first few weeks. Water deeply once a week if there is no rain. Mulch around plants with straw or grass clippings. This keeps soil cool, retains moisture, and suppresses weeds.
Avoid overhead watering in the evening. Wet leaves overnight can lead to fungal diseases. Water at the base of plants in the morning.
Common Mistakes When Planting Chicory
Planting Too Early
Many gardeners get excited and plant chicory too early in spring. A late frost can kill young seedlings. Always check the forecast. If frost is predicted, cover plants with row covers or cloches. Wait until soil temperature is consistently above 45°F.
If you start seeds indoors, do not transplant too early. Harden off seedlings for a week before moving them outside. Cold shock can stunt growth.
Planting Too Late
Summer heat is the enemy of chicory. If you plant in late spring or early summer, the plants will bolt quickly. Bolting means they send up flower stalks and leaves become bitter. For spring harvest, plant no later than 4 weeks after the last frost.
In warm climates, avoid planting from May through August. The heat stress will ruin the crop. Wait for cooler fall weather.
Poor Soil Preparation
Chicory is not fussy, but it hates compacted soil. If you skip tilling or loosening the soil, roots will be stunted. Take time to prepare the bed properly. Add organic matter to improve soil structure.
Also, test your soil pH. Chicory prefers slightly acidic to neutral soil. If pH is below 6.0, add lime. If above 7.0, add sulfur. Proper pH ensures nutrient availability.
Harvesting Chicory At The Right Time
Harvesting Leaves
You can start harvesting leaves when they are 6 to 8 inches tall. Pick outer leaves first, leaving the inner rosette to grow. This gives you multiple harvests from one plant. For baby greens, cut the whole plant at 4 inches tall.
Harvest in the morning when leaves are crisp. Rinse and dry them immediately. Store in a plastic bag in the fridge for up to a week. Do not wash until ready to use.
Harvesting Roots
Dig roots in late fall after the first frost. The frost improves flavor by converting starches to sugars. Use a garden fork to loosen the soil around the roots. Pull gently to avoid breaking them.
Wash roots thoroughly and cut off the tops. Store in a cool, dark place like a root cellar. They keep for several months. Roast and grind them for a caffeine-free coffee substitute.
Frequently Asked Questions
Can I plant chicory in the summer?
Summer planting is not recommended in most climates. Heat causes chicory to bolt and become bitter. In cool coastal areas, you might get away with it. But for most gardeners, spring and fall are best.
How late can I plant chicory in the fall?
Plant chicory 6 to 8 weeks before the first expected frost. This gives seedlings time to establish. In mild climates, you can plant as late as October. In cold climates, plant by late August.
Should I soak chicory seeds before planting?
Soaking is not necessary. Chicory seeds germinate quickly without soaking. If you want to speed things up, soak them for 2 to 4 hours. Do not soak longer, as seeds can rot.
Can I grow chicory in containers?
Yes, but choose deep containers for root varieties. Use pots at least 12 inches deep. For leaf varieties, 6-inch deep pots work fine. Ensure good drainage and use quality potting soil.
Does chicory come back every year?
Chicory is a perennial in zones 3-8. It will come back from the roots each year. In warmer zones, it may act as a biennial. You can treat it as an annual for best leaf quality.
Final Tips For Success
Chicory is a forgiving plant once you get the timing right. Start with a small patch to learn its needs. Keep a garden journal to track planting dates and harvests. Over time, you will find the perfect window for your specific location.
Remember that chicory is a cool-season crop. It thrives in temperatures between 50°F and 70°F. Protect it from extreme heat and cold. With proper timing, you will enjoy fresh greens and roots for months.
If you live in a region with unpredictable weather, use row covers or cold frames. These tools extend your growing season and protect plants from frost. They also help warm the soil in spring for earlier planting.
Experiment with different varieties. ‘Radicchio’ is great for salads. ‘Magdeburg’ is best for roots. ‘Puna’ is a forage variety. Each has slightly different planting needs. Read the seed packet for specific advice.
Finally, do not be afraid to make mistakes. Even if you plant a bit too early or late, chicory often survives. Learn from each season and adjust your timing next year. Gardening is a journey, not a destination.
By following this guide on When To Plant Chicory, you will set yourself up for a bountiful harvest. The key is patience and attention to soil temperature. Once you master the timing, chicory will become a reliable staple in your garden.
Happy planting, and enjoy your homegrown chicory!
