Oklahoma gardeners should plant chicory in early spring, as the plant prefers cooler temperatures before summer arrives. Knowing the best time to plant chicory in oklahoma can make the difference between a lush harvest and a disappointing patch. Chicory is a tough, versatile plant that thrives in Oklahoma’s varied climate, but timing is everything.
Chicory is not just a pretty blue flower. It is a leafy green, a coffee substitute, and a soil improver all in one. If you want to grow it successfully in Oklahoma, you need to work with the seasons. Let’s break down exactly when and how to plant chicory for the best results.
Understanding Oklahoma’s Climate For Chicory
Oklahoma has a mix of humid subtropical and semi-arid climates. Summers are hot and often dry. Winters can be cold but are usually mild. Chicory is a cool-season crop, so it does not like extreme heat.
The plant grows best when temperatures are between 45°F and 75°F. Once summer hits with 90°F days, chicory tends to bolt. Bolting means it flowers and goes to seed, making the leaves bitter. That is why planting early is so important.
Spring Planting Window
For most of Oklahoma, the ideal spring planting window is from mid-March to mid-April. The soil should be workable and not frozen. You want to get the seeds in the ground about two to four weeks before the last expected frost.
In northern Oklahoma, the last frost usually happens around early April. In southern parts, it can be as early as late March. Check your local frost dates to be sure. Planting too early in cold, wet soil can cause seeds to rot. Planting too late means the plants will struggle in the heat.
Fall Planting Option
You can also plant chicory in late summer for a fall harvest. The best time for fall planting is from late August to mid-September. This gives the plants time to establish before the first frost. Fall-planted chicory often has a milder flavor because of the cooler nights.
Fall planting works well if you missed the spring window. Just make sure the soil is still warm enough for germination. Chicory seeds need soil temperatures around 50°F to 70°F to sprout.
Best Time To Plant Chicory In Oklahoma
Now let’s get specific. The best time to plant chicory in oklahoma is early spring, specifically between March 15 and April 15. This timing aligns with the plant’s natural growth cycle. It allows chicory to develop strong roots before the summer heat arrives.
If you plant during this window, you can expect harvestable leaves by late April or early May. The plants will stay productive for about six to eight weeks. After that, they will likely bolt as temperatures rise.
For fall planting, aim for August 20 to September 10. This gives the plants about 60 days of good growing weather before the first frost. Fall chicory can be harvested until a hard freeze hits.
Soil Preparation Tips
Chicory is not picky about soil, but it does best in well-drained loam. Sandy soils work too, but clay soils can be problematic. If your soil is heavy clay, consider raising the beds or adding organic matter.
- Test your soil pH. Chicory prefers a pH between 6.0 and 7.0.
- Add compost or aged manure a few weeks before planting.
- Remove rocks and weeds from the planting area.
- Rake the soil smooth for even seed placement.
Seed Sowing Techniques
Chicory seeds are small. You can sow them directly in the garden or start them indoors. Direct sowing is easier and works well for most gardeners.
- Make shallow rows about 1/4 inch deep.
- Space rows 12 to 18 inches apart.
- Sow seeds thinly, about one seed per inch.
- Cover lightly with soil and water gently.
- Thin seedlings to 6 to 8 inches apart once they have two true leaves.
If you start seeds indoors, do so about four weeks before your planned transplant date. Use small pots or seed trays. Transplant seedlings outdoors after the last frost.
Watering And Care
Chicory needs consistent moisture, especially during germination. Keep the soil damp but not waterlogged. Once established, chicory is fairly drought-tolerant. However, regular watering produces tender leaves.
Water deeply once or twice a week, depending on rainfall. Mulch around the plants to retain moisture and suppress weeds. Chicory does not need much fertilizer. A light application of balanced fertilizer at planting time is enough.
Chicory Varieties For Oklahoma
Not all chicory varieties are the same. Some are better suited for Oklahoma’s climate. Here are a few reliable options:
- Radicchio: A red-leaved variety that is great for salads. It matures in about 60 days.
- Sugar Loaf: A tall, tight-headed chicory that is sweet and mild. Good for spring planting.
- Catalogna: A leafy type with dandelion-like leaves. It handles heat better than others.
- Witloof: Also known as Belgian endive. It is grown for its blanched heads. Needs a longer growing season.
Choose a variety that matches your taste and growing goals. Radicchio and Sugar Loaf are popular choices for Oklahoma gardens.
Companion Planting With Chicory
Chicory grows well with many vegetables. It can help deter pests like aphids and cabbage worms. Good companions include:
- Carrots
- Onions
- Lettuce
- Beets
- Tomatoes
Avoid planting chicory near fennel or beans. These plants can compete for nutrients or attract similar pests.
Harvesting Chicory Leaves
You can start harvesting chicory leaves when they are about 4 to 6 inches tall. Pick the outer leaves first, leaving the inner ones to grow. This method gives you a continuous harvest for weeks.
For the best flavor, harvest in the morning when the leaves are crisp. Wash them thoroughly and store in the refrigerator. Chicory leaves can be slightly bitter, but blanching them in boiling water for a minute reduces the bitterness.
Using Chicory Roots
Chicory roots are often used as a coffee substitute or additive. To harvest roots, wait until the plants are mature, usually after 90 to 120 days. Dig up the roots in late fall after the first frost. The cold makes the roots sweeter.
Clean the roots, chop them into small pieces, and roast them in the oven at 250°F until dry and brown. Grind the roasted roots and use them like coffee grounds. It is a caffeine-free alternative with a rich, earthy flavor.
Common Problems And Solutions
Chicory is generally low-maintenance, but a few issues can arise. Here are common problems and how to handle them:
- Bolting: Caused by heat or stress. Plant early and keep soil moist.
- Bitter leaves: Often from heat or lack of water. Harvest young leaves and water regularly.
- Pests: Aphids and slugs can be a problem. Use insecticidal soap or diatomaceous earth.
- Diseases: Fungal issues like powdery mildew can occur. Ensure good air circulation and avoid overhead watering.
Extending The Growing Season
If you want to grow chicory longer into the summer, try these tips:
- Plant in partial shade to reduce heat stress.
- Use shade cloth to protect plants from intense sun.
- Water more frequently during hot spells.
- Mulch heavily to keep soil cool.
These methods can delay bolting by a few weeks. But remember, chicory is naturally a cool-season crop. It is better to plant it at the right time than to fight the heat.
Frequently Asked Questions
Can I plant chicory in Oklahoma in the summer?
Summer planting is not recommended. The heat causes chicory to bolt quickly. Stick to spring or fall planting for the best results.
How long does chicory take to grow from seed?
Chicory leaves are ready to harvest in about 50 to 60 days. Roots take longer, usually 90 to 120 days. Fall-planted chicory may take a bit longer due to cooler temperatures.
Does chicory come back every year in Oklahoma?
Chicory is a perennial in many areas, but in Oklahoma, it is often grown as an annual. It may survive mild winters and regrow, but it is not guaranteed. Most gardeners replant each year.
What is the best soil for chicory in Oklahoma?
Well-drained loam with a pH of 6.0 to 7.0 is ideal. Sandy soils work, but clay soils need amendment. Adding compost improves drainage and fertility.
Can I grow chicory in containers in Oklahoma?
Yes, chicory grows well in containers. Use a pot that is at least 12 inches deep. Ensure good drainage and water regularly. Container-grown chicory may need more frequent watering.
Final Tips For Success
Planting chicory at the right time is the most important step. Early spring gives you the best chance for a good harvest. Fall planting is a solid backup option.
Prepare your soil well, water consistently, and harvest regularly. Chicory is a forgiving plant that rewards you with tasty leaves and useful roots. With a little planning, you can enjoy fresh chicory from your Oklahoma garden.
Remember to check your local frost dates and adjust your planting schedule accordingly. Every garden is a little different, so observe your plants and learn from each season. Happy growing.
