Planting timing
Clemson HGIC 1251: grow Chinese vegetables including tatsoi in early spring or fall. “Sow seed in the fall or plant transplants in spring … Spring-sown plants are prone to bolting. … mature plants can withstand frost and snow.” (Clemson Chinese vegetables) UC Sonoma: one of the most cold-tolerant greens (to 20°F). (UC Asian greens)
Depth and spacing
Clemson: 4 to 6 inches between plants; rows 2 to 3 feet. UC: sow ¼–½ in deep; thin while harvesting.
Sun, soil and water
Cool, moist brassica culture. UC: little irrigation needed when winter rains are plentiful.
Care
Prefer fall crops to reduce spring bolt (Clemson). Row covers help with flea beetles and leaf beetles.
Harvest
Fast maturity (Clemson). UC: cut about 1 inch above ground for cut-and-come-again; flat rosette about 8 inches across.
Pests and diseases
Clemson notes yellow-margined leaf beetle on tatsoi; flea beetles typical on brassicas — row cover cultural control.
