Best Planting Window for Cold / Highland
Turmeric is not recommended for Cold / Highland.
No Australian source covers turmeric for the cold highlands. Frost kills the leaves and it needs 7 to 10 warm months, so it is not viable in the ground. One national guide says it can be grown anywhere in a pot against a frost protected wall, so a heated greenhouse or a warm indoor pot is the only option.

How to Grow Turmeric in Cold / Highland Australia
- Soil
- Rich, free draining soil that holds moisture, enriched with compost and well rotted manure. In pots, use a good potting mix with drainage holes. It does not tolerate waterlogging.
- Salt
- Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
- Sunlight
- Part shade or dappled light, ideally gentle morning sun with afternoon shade. Heavy shade slows rhizome development, and The Seed Collection lists part or full sun, so a bright but not scorching spot suits it best. Choose a sheltered position away from wind.
- Spacing
- 30cm apart, 40cm between rows
- Watering
- Keep the soil consistently moist but not soggy through the growing season, and water regularly in the dry season. Cut back through late autumn and winter as the leaves die back, then increase watering as spring warms.
- Good companions
- Lemongrass, Ginger, Coconut, Galangal, Taro
- Grow before it
- Fruiting crops (Tomato, Capsicum, Zucchini)
- Grow after it
- Legumes (Beans - Dwarf, Peas, Broad Beans)
Give the bed 3 turns before root crops go back in. Roots fork and go leafy in fresh manure, so they take the bed after the heavy feeders have used it.
