Growing it

Propagation: division
When to plant: spring
Overwintering: In cooler climates, dig up the rhizomes after the foliage dies back and store them in a cool, dry place until spring. If kept in a pot, bring it indoors before the first frost.
In containers: It grows very well in containers, provided you use a pot at least 30 cm wide and deep.

Rhizome Division

1. Carefully dig up the mature rhizome clump.
2. Break or cut the rhizome into sections, ensuring each piece has at least one bud.
3. Plant the sections about 5 cm deep in rich, well draining soil.

Plant turmeric in the shade of larger tropical plants to mimic its natural forest floor habitat.
