Growing Tips
When to Start
Spring: Start indoors about 6-8 weeks before the last frost date. (Late January-Early March GA)
Spring Transplant: After the danger of frost has passed. (Mid-March through the end of April for GA)
Fall: Start 14-16 weeks before the first frost date. (End of July through Mid-August for GA).
Fall Transplant: About 8 weeks before the first frost date (September for GA).
How to Start
Start indoors about 6-8 weeks before the last frost date. Using sterile, pre-moistened seed starting mix, sow seeds to a depth of ¼ inches in seed cells. Then place the cells/pots under grow lights and pot up as needed. Transplant after hardening off and space to 12-24 inches apart. Plant in part shade to full sun beds.
For fall plants, start indoors 14-16 weeks before the first frost date. Transplant after hardening off 8 weeks before the first frost date. Fall plants can be planted in full sun.
Use succession planting for a continual harvest. Transplant seedlings every week to every other week. If you plan on doing this, try using succession planting from the beginning. Sow seeds every week to every other week. This will help ensure your seedings will not all be ready for transplant at the same time.
Care
Bok Choy is a cool-season crop that is prone to bolting in hot weather. This can be particularly challenging for spring plantings in GA.
To further discourage bolting as a spring crop, try planting in part shade or use shade cloths for plants in full sun. Pests can be a problem, try using row covers to keep pests out.
Bok Choy likes rich, well-draining soil. Use row covers to protect from any unexpected freezes. Mulch to help keep the ground moist and cool. Keep the plants well-watered during dry periods to promote rapid, uninterrupted growth. If slug and snails are a problem, try using egg shell barriers.
Harvest
Harvest heads when they become firm. Cut the stems at the soil level and remove the outer leaves.
Harvest Choy Sum 50 days after starting just like other Bok Choy. The flowers and stocks are considered a gourmet delicacy.
How to use
Enjoy fresh, boiled, sautéed, steamed, or stir-fried. Ideal for salads and soups.
Seed Saving
Isolation Distance
Insect-dependent and biennial, bok choy will cross with other Brassica rapa like cabbage and turnips. Separate by 1 mile for reliable distance isolation. Allow seeds to mature and dry on the plants before harvesting. Seeds will develop in the 2nd year.
Instructions
Select the plants to allow to go to seed. Allow seeds to dry on the plant before harvesting. Store them in a dry place and wait until they are thoroughly dry.
Seeds and finer chaff are easy to separate by a variety of methods. One way is to use two screens of varying mesh, one a little smaller than the seeds and the other a little larger. The first screen lets anything smaller than the seeds fall through, and the second lets the seeds through and stops anything larger.
Features
- Suzhou Baby: Heirloom. Tightly packed heads that remain flavorful even when the leaves get large. It is bolt-resistant and both heat and cold-tolerant.
- Shanghai Green: Heirloom. This jade-green variety is prized by chiefs. They are extra tender.
- Baby Choi: Heirloom. Great stir-fried, steamed, or sautéed. Six inches long.
- Hedou Tiny: Heirloom. Extra-dwarf heads; a perfect bite-sized veggie.
Bok Choy are biannual. They will flower and produce seeds in the second year. They require vernalization (the process of overwintering).
