Curcuma longa is a sterile triploid organism that has evolved through natural selection and propagation. A relative of ginger and sharing similar growing conditions, it is a hybrid of the wild turmeric found in Southern Asia, with India being the predominant producer of growing turmeric plants for trade. Turmeric can also be found in China (where it has been cultivated since the 7th century), Jamaica, Indonesia and Malaysia. Let’s learn more about this plant, its benefits and how to grow turmeric in the home or garden.

Can You Grow Turmeric?
So can you grow turmeric? Sure, although turmeric plants are really better suited to open fields with a climate that is not easily found in North America. That said, with the correct conditions, I would give it a go.
A hardy ginger, growing turmeric plants require certain conditions such as humid warm weather and significant rain. When growing these plants in the home or garden, temperatures between 68-86 F. (20-30 C.) are required.
How to Grow Turmeric?
These hardy ginger relatives die back in the winter and pop back up in the spring, growing from a system of rhizomes and propagating via vegetative reproduction. This means that each piece of rhizome has the capacity to become a new plant, provided each division has a piece of the crown.
You can start growing turmeric this way with a small piece of rhizome “gifted” to you from another or purchased from a nursery. Either way, you will soon have a forest of turmeric plants as they grow and spread rapidly.
When one is growing turmeric, choose a morning sun exposure with afternoon part shade and moist clay to part clay soil.
Planting takes place in the spring. Plant the section 4 inches deep, unless container gardening in which case 1 to 2 inches may be sufficient.
Maintain adequate moisture and dig the roots up in late fall or early winter when the plant is dormant. Remember these plants may be injured if temperatures fall below 50 F (10 C.).
