Tatsoi Growing Guide

Brassica rapa subsp. narinosa

Tatsoi

Crop Rotation Group

Brassicas (Cabbage family) ●

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

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.
