Growing Tips, Tricks and FAQs
Growing Tips
Choy Sum is a fast-growing leafy green that is valued for both its tender stems and small, edible yellow flowers. This plant prefers cooler temperatures, making it ideal for spring and fall growing. It thrives in well-drained, fertile soil rich in organic matter, and benefits from consistent moisture throughout the growing season.
When to Grow
Choy Sum is best planted in early spring or late summer, as it prefers cooler growing conditions and can tolerate light frost. The 50-day variety refers to its relatively quick maturity, allowing you to harvest in as little as 50 days from sowing. In regions with mild winters, you can also plant Choy Sum in the fall for a winter harvest.
How to Sow and Plant
Sow Choy Sum seeds directly into the garden about 1/4 inch deep. Space the seeds about 4-6 inches apart in rows that are 12-18 inches apart. For a continuous harvest, consider sowing seeds every 2-3 weeks during the growing season. If starting indoors, begin seeds 4-6 weeks before the last frost date and transplant them outside once the seedlings have 2-3 true leaves.
How to Grow
Choy Sum requires consistent moisture to grow, so regular watering is essential, especially during dry spells. Mulching can help retain soil moisture and keep weeds down. This plant prefers full sun but can tolerate partial shade, particularly in warmer climates. Fertilize the plants regularly with a balanced organic fertilizer or by side-dressing with compost.
How to Save
Bok choy is an annual, completing its life cycle in one year. To avoid selecting bolt-prone plants, don't save seeds from prematurely bolted ones. Let plants mature fully, harvest the dried pods, crumble the small round seeds into a jar or bag, then seal and store the seeds in a cool, dark, dry place. Bok choy cross-pollinates with other rapa species but not with different species of Brassica, so it's safe to grow it next to mustard greens (Brassica juncea), for example. To ensure seed purity, isolate your bok choy from other blooming B. rapa by about a half mile or use caging techniques. Allow your healthiest plants to flower for a strong, diverse seed pool.
FAQ
When is the best time to harvest Choy Sum?
Harvest Choy Sum when the plants are about 12-18 inches tall, and before the flowers fully open, typically around 50 days after planting. Both the leaves and flower stalks are edible.
Can Choy Sum be grown in containers?
Yes, Choy Sum can be grown successfully in containers. Choose a pot that is at least 8-10 inches deep with good drainage. Ensure the soil stays consistently moist and fertilize it regularly.
Is Choy Sum frost-tolerant?
Choy Sum can tolerate light frosts, which makes it suitable for planting in early spring or fall. However, it should be protected from hard frosts to avoid damage to the plants.
