Tatsoi Growing Guide

Tatsoi, also known as Spinach Mustard

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 autumn, exposure to light frost can improve tatsoi's flavor.

Feeding

Mix a light application of a balanced organic fertiliser into the soil prior to planting.

Companions

Dill, Mint, Nasturtium, Sage, Lettuce, Mustard, Kale, Endive and Mizuna.

Spacing

Single Plants: 20cm (7") each way (minimum)
Rows: 20cm (7") with 20cm (7") row gap (minimum)

Sow and Plant

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.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.

Notes

This beautiful little mustard cousin often grows better in autumn than in spring.

Harvesting

Gather individual leaves, or pull whole plants for use in the kitchen.

Troubleshooting

Use fine mesh or exclusion netting over the summer to prevent butterflies laying eggs on the underside of leaves - caterpillars can destroy these plants.
