Soil
Any sunny site with good drainage.
Position
Full sun.
Frost tolerant
Tatsoi can tolerate light frost, but exposure to cold temperatures in spring can trigger early bolting. In fall, exposure to light frost can improve tatsoi’s flavor.
Feeding
Mix a light application of a balanced organic fertilizer into the soil prior to planting.
Companions
Lettuce, Mizuna, Mustard, Endive and Johnny Jump Up. Also grown with other greens found in mesclun mixtures. In fall, tatsoi looks beautiful with pansies and parsley.
Spacing
Single Plants: 7″ (20cm) each way (minimum)
Rows: 7″ (20cm) with 7″ (20cm) row gap (minimum)
Sow and Plant
Sow tatsoi in spring and again in late summer for harvest in fall. Sow in double rows, with rows spaced 10 inches (25 cm) apart. Plant seeds 2 inches (5 cm) apart and barely cover them with soil. Gradually thin to 8 inches (20 cm) apart.
Notes
This beautiful little mustard cousin often grows better in fall than in spring.
Harvesting
Gather individual leaves, or pull whole plants for use in the kitchen.
Troubleshooting
Flea beetles often chew small holes in tatsoi leaves in spring, but are less of a problem in the fall.
