Common Questions

Tatsoi questions

What zones can Tatsoi grow in?

Tatsoi is hardy in USDA Zones 4, 5, 6, 7, 8, 10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Tatsoi deer resistant?

Not reliably. Deer may browse Tatsoi, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does Tatsoi bloom?

Tatsoi typically blooms in early summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Tatsoi need full sun?

Tatsoi does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
