Description

(Brassica rapa subsp. narinosa). Tatsoi is nicknamed Vitamin Green, and rightfully so. This gourmet green is known as one of the richest sources of vitamin C and it is packed with other incredible vitamins, minerals, and health-promoting compounds! Tatsoi also boasts glucosinolates (which have been extensively studied for their potential in lowering the risk of some cancers) and carotenoids, which promote eye health. You won’t have to bargain with your kids to get them to eat this veggie. It’s super sweet and easy to love, with a mild and refreshing flavor. The low-growing rosettes are comprised of tiny, glossy spoon-shaped leaves that boast crisp and juicy mouthfeel.

Growing Tips:Tatsoi is a cold-hardy Asian green that flourishes in cool temperatures. It thrives in full sun to partial shade and prefers well-drained, fertile soil rich in organic matter. This leafy green is easy to grow and can be cultivated in both garden beds and containers.

When to Grow

Tatsoi can be planted in early spring or late summer for a fall harvest. Sow seeds about 2-3 weeks before the last expected frost in spring, or during late summer to enjoy a fall crop. This cold-hardy green can be grown in most regions as a spring and fall crop, and overwintered where winters are mild. Check local frost dates to determine the best time for planting.

How to Sow and Plant

Direct sow seeds 1/4 inch deep in rows spaced 10 inches apart, with seeds planted 2 inches apart. As seedlings grow, thin them to about 12 inches apart to allow ample space for mature growth. If starting indoors, transplant seedlings outdoors when they have at least two true leaves and the danger of frost has passed.

How to Grow

Tatsoi requires consistent moisture, so water regularly to keep the soil evenly moist but not waterlogged. Fertilize the soil with a balanced organic fertilizer before planting, and consider adding compost to improve soil fertility. Tatsoi can be harvested as individual leaves or as a whole plant, depending on your preference. It’s best to harvest in the morning when the leaves are most hydrated​.

How to Save Seeds

Like bok choy, tatsoi 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 and tatsoi cross-pollinate with other rapa species but not with different species of Brassica, so it's safe to grow them 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

Can Tatsoi be grown in containers?

Yes, Tatsoi grows well in containers. Ensure the container has good drainage and is at least 6-8 inches deep to accommodate its root system.

What pests should I watch out for when growing Tatsoi?

Common pests include flea beetles and cabbage loopers. Using row covers and applying organic insecticides like neem oil can help manage these pests.

When can I harvest Tatsoi?

Tatsoi can be harvested as early as 20–30 days for baby greens or 50–55 days for mature plants​.
