Arkansas’s humid summers push bok choy planting to early spring or late summer for a fall harvest. Knowing the best time to plant bok choy in arkansas can make the difference between a crisp, tender crop and a bitter, bolted mess. This guide walks you through exactly when to sow seeds or set out transplants for success in the Natural State.
Bok choy is a cool-season crop that thrives in temperatures between 55°F and 70°F. In Arkansas, that means you have two main planting windows: early spring and late summer. Get the timing right, and you’ll enjoy homegrown bok choy for salads, stir-fries, and soups.
Best Time To Plant Bok Choy In Arkansas
The absolute best time to plant bok choy in arkansas is about 2 to 4 weeks before the last expected spring frost. For most of Arkansas, that falls between mid-March and early April. The second ideal window is 6 to 8 weeks before the first fall frost, typically from late July through mid-August.
Bok choy is a fast grower, ready to harvest in just 45 to 60 days. Because it bolts (goes to seed) quickly in heat, you need to plan around Arkansas’s hot summers. Spring plantings should be timed so the crop matures before temperatures consistently hit 80°F. Fall plantings should mature before the first hard freeze.
Understanding Arkansas’s Growing Zones
Arkansas spans USDA hardiness zones 6b in the north to 8a in the south. This affects your exact planting dates. Northern Arkansas (Fayetteville, Mountain Home) has cooler springs and earlier frosts. Southern Arkansas (Texarkana, El Dorado) warms up faster and has a longer growing season.
- Zone 6b (northern AR): Last frost around April 15–20. Plant spring bok choy in late March to early April.
- Zone 7a/7b (central AR): Last frost around April 5–10. Plant spring bok choy in mid-March to early April.
- Zone 8a (southern AR): Last frost around March 25–30. Plant spring bok choy in early to mid-March.
For fall planting, reverse the logic. In northern Arkansas, start seeds indoors in late July and transplant in mid-August. In southern Arkansas, you can direct sow in early September.
Spring Planting: The Early Window
Spring is the most reliable season for bok choy in Arkansas. The soil is cool, the days are lengthening, and pests are still waking up. Here’s how to nail the spring planting window.
Step 1: Check Soil Temperature
Bok choy seeds germinate best when soil temperatures are between 45°F and 85°F. The sweet spot is 60°F to 70°F. Use a soil thermometer to check your garden bed. If the soil is still cold and wet, wait a week.
Step 2: Start Seeds Indoors (Optional)
You can start seeds indoors 4 to 6 weeks before your last frost date. Use seed-starting mix and keep them under grow lights or in a sunny window. Transplant seedlings when they have 3 to 4 true leaves and the soil is workable.
Step 3: Direct Sow or Transplant
Direct sowing is simpler. Plant seeds ¼ to ½ inch deep, 1 inch apart, in rows 12 to 18 inches apart. Thin seedlings to 6 to 8 inches apart once they have two leaves. For transplants, space them 6 to 8 inches apart in the garden.
Step 4: Protect from Late Frosts
Arkansas springs are unpredictable. A late frost in April can damage young bok choy. Keep row covers or old bedsheets handy. Cover plants overnight if frost is predicted, and remove covers in the morning.
Fall Planting: The Second Window
Fall planting is often overlooked, but it’s actually the best time for bok choy in Arkansas. The soil is warm, which speeds germination, and the cooling temperatures prevent bolting. Plus, fall crops often have better flavor because of the cooler nights.
Step 1: Calculate Your Fall Planting Date
Count backward from your first expected fall frost. For northern Arkansas (first frost around October 15), plant 6 to 8 weeks earlier, meaning late July to early August. For central Arkansas (first frost around October 25), plant in early to mid-August. For southern Arkansas (first frost around November 5), plant in late August to early September.
Step 2: Start Seeds Indoors for Fall
Fall planting in Arkansas often benefits from starting seeds indoors. The heat of late July can stress direct-sown seeds. Start seeds indoors in a cool, shaded spot or air-conditioned room. Transplant outdoors after 3 to 4 weeks, when temperatures start to moderate.
Step 3: Direct Sow with Shade
If you direct sow in late summer, provide shade for the seedlings. Use a shade cloth or plant on the north side of taller crops like tomatoes or corn. Keep the soil consistently moist to help seeds germinate in the heat.
Step 4: Extend the Season
Bok choy can tolerate light frosts, which actually improve its sweetness. Use row covers or cold frames to protect plants from hard freezes. In southern Arkansas, you may be able to harvest into December.
Choosing The Right Bok Choy Variety For Arkansas
Not all bok choy varieties perform the same in Arkansas’s climate. Some are more heat-tolerant, while others mature faster. Here are top picks for the Natural State.
- Baby Bok Choy: Matures in 35–40 days. Great for spring and fall. Compact size works well in small gardens.
- Joi Choi: A hybrid that resists bolting. Good for spring planting. Large, white stems and dark green leaves.
- Shanghai Green: Heat-tolerant variety. Ideal for late summer planting. Light green stems and tender leaves.
- Win-Win: Another heat-tolerant hybrid. Matures in 45 days. Works for both spring and fall.
- Mei Qing Choi: Baby bok choy type. Very fast (35 days). Perfect for succession planting.
Soil Preparation And Planting Tips
Bok choy grows best in rich, well-draining soil with a pH between 6.0 and 7.5. Before planting, amend your soil with compost or well-rotted manure. This provides the nitrogen bok choy needs for leafy growth.
- Test your soil pH with a simple kit. Adjust with lime to raise pH or sulfur to lower it.
- Add 2 to 3 inches of compost to the planting bed. Work it in to a depth of 6 inches.
- Apply a balanced fertilizer (10-10-10) at planting time. Follow package rates.
- Water thoroughly after planting. Keep soil consistently moist but not waterlogged.
- Mulch around plants with straw or shredded leaves to retain moisture and suppress weeds.
Watering And Fertilizing Schedule
Bok choy has shallow roots, so it needs regular watering. Aim for 1 to 1.5 inches of water per week, either from rain or irrigation. In Arkansas’s hot summers, you may need to water daily during dry spells.
Fertilize every 2 to 3 weeks with a liquid fertilizer high in nitrogen. Fish emulsion or compost tea works well. Stop fertilizing once the plants start to form heads, usually around 30 days after planting.
Common Pests And Diseases In Arkansas
Bok choy attracts several pests in Arkansas. The most common are flea beetles, aphids, and cabbage worms. Here’s how to manage them.
- Flea beetles: Small, jumping beetles that create tiny holes in leaves. Use row covers to exclude them. Apply diatomaceous earth if needed.
- Aphids: Soft-bodied insects on leaf undersides. Spray with a strong jet of water or use insecticidal soap.
- Cabbage worms: Green caterpillars that eat large holes in leaves. Handpick them or use Bacillus thuringiensis (Bt).
- Slugs and snails: Common in wet springs. Set out beer traps or use iron phosphate bait.
Diseases are less common but can include downy mildew and black rot. Prevent them by spacing plants for good air circulation and avoiding overhead watering in the evening.
Harvesting Bok Choy At The Right Time
Bok choy is ready to harvest when the stems are thick and the leaves are dark green. For baby bok choy, harvest when plants are 4 to 6 inches tall, about 35 days after planting. For full-sized heads, wait until they reach 8 to 12 inches tall, usually 45 to 60 days.
Cut the entire plant at the base with a sharp knife. You can also harvest outer leaves individually, allowing the inner leaves to continue growing. This gives you a longer harvest period.
Succession Planting For Continuous Harvest
To enjoy bok choy all season, practice succession planting. Sow a new batch of seeds every 2 to 3 weeks during your planting windows. This ensures you always have young plants coming along as older ones are harvested.
In spring, plant your first batch in mid-March, then again in early April, and a final spring batch in late April. For fall, start in late July, then again in mid-August, and a final batch in early September.
Common Mistakes And How To Avoid Them
Even experienced gardeners make mistakes with bok choy. Here are the most common ones in Arkansas and how to avoid them.
- Planting too late in spring: If you plant in May, the heat will cause bolting. Stick to March and April.
- Planting too early in fall: Late July heat can kill seedlings. Start seeds indoors or provide shade.
- Overcrowding: Thin seedlings to 6 inches apart. Crowded plants compete for nutrients and are more prone to disease.
- Underwatering: Bok choy needs consistent moisture. Inconsistent watering leads to tough, bitter leaves.
- Ignoring pests: Check plants daily for pests. Early intervention is key to preventing infestations.
Growing Bok Choy In Containers
If you have limited space, bok choy grows well in containers. Choose a pot at least 6 inches deep and 12 inches wide. Use a high-quality potting mix and ensure the container has drainage holes.
Place the container in a spot that gets 4 to 6 hours of sunlight daily. Water more frequently than in-ground plants, as containers dry out faster. Fertilize every 2 weeks with a diluted liquid fertilizer.
Bok Choy Companion Planting
Companion planting can improve your bok choy crop. Good companions include beets, carrots, onions, and herbs like dill and mint. These plants repel pests or improve soil health.
Avoid planting bok choy near other brassicas like broccoli, cauliflower, or kale. They compete for nutrients and attract the same pests. Also avoid strawberries and pole beans, which can inhibit growth.
Storing And Using Fresh Bok Choy
Fresh bok choy stores well in the refrigerator. Wrap it in a damp paper towel and place it in a plastic bag. It will keep for 5 to 7 days. For longer storage, blanch and freeze it for up to 6 months.
Use bok choy raw in salads, stir-fried with garlic and ginger, or added to soups and stews. The stems are crunchy and the leaves are tender. Both parts are edible and nutritious.
