When to plant Tatsoi
Tatsoi is a cold-hardy Asian green grown as a spring or fall crop from direct seeding or transplants; prostrate types withstand hard freezes and can be harvested into winter. High temperatures and low water cause it to bolt, so protect spring plantings from summer heat (NC State).
