How to Grow Tatsoi in Mediterranean Australia
- Soil
- Free draining soil with plenty of organic matter. Dig in well rotted manure or compost a few weeks before sowing (Succeed Heirlooms). Use a raised bed or pot if the soil is clay or compacted.
- Salt
- Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
- Sunlight
- Full sun or light shade (Succeed Heirlooms, The Seed Collection).
- Spacing
- 20cm apart, 40cm between rows
- Watering
- Keep the soil moist and well watered (The Seed Collection). Mulch to hold the moisture in.
- Good companions
- Nasturtium, Dwarf Beans, Onion, Cucumber, Beetroot

- Tomato, Climbing beans, Strawberry, Other brassicas in the same bed next season
- Grow before it
- Legumes (Beans - Dwarf, Peas, Broad Beans)

Give the bed 3 turns before brassicas go back in. The cabbage family is hungry for nitrogen and shares club root and other soil diseases.
