How to Grow Tatsoi

Overview

Tatsoi, also known as tat soi or tat choy, is a delicious and versatile leafy green that has been enjoyed in Asia for centuries. Closely related to bok choy, this member of the Brassica rapa family has gained popularity in North American cuisine and can now be found growing in gardens around the world. With its mild, sweet flavor and tender leaves, tatsoi is a great addition to salads, stir-fries, and other dishes.

Growing Conditions

Tatsoi thrives in well-draining soil rich in organic matter and full sun to partial shade. This cool-season crop prefers temperatures between 60°F and 70°F (15°C-21°C) and can tolerate frost. In hot weather, tatsoi may bolt or become bitter, so it's best to grow this plant during the cooler months of spring and fall.

Planting & Care

Tatsoi seeds can be directly sown in the garden or started indoors and transplanted later. If starting indoors, sow seeds 4-6 weeks before the last expected frost date. Transplant seedlings outdoors when they have reached a few inches in height and the risk of frost has passed. Space plants about 6-8 inches apart in rows spaced 12-18 inches apart. Keep soil evenly moist and fertilize regularly with an organic compost or fertilizer to ensure healthy growth.

Common Problems

Tatsoi is generally a hardy plant, but watch for signs of pests like aphids or flea beetles, which can be controlled using organic insecticidal soap or Diatomaceous Earth. If your plants bolt due to heat stress, you may notice them sending up a flower stalk; simply remove these to encourage leaf growth.

Harvest or Enjoy

Tatsoi greens are ready for harvest when they reach about 4-6 inches in height, usually around 30 days after sowing seeds. Cut the outer leaves as needed, allowing some of the inner leaves to continue growing for a successive harvest. For
