Last month, I wrote about growing and marketing baby ginger. This month, I’ll tell you about turmeric, a crop that is often grown as a companion to ginger. Although turmeric is generally grown the same way as ginger, that’s where the similarities end. Turmeric has different germination and harvest requirements, projected yields, and financial margins. Marketing a product that most people don’t recognize, having never seen it as anything but a yellow powder in a spice bottle, also takes much more effort.

Turmeric, Curcuma longa, is in the ginger family and is native to Southeast Asia, where it is an important culinary ingredient. More recently, it has gained a reputation for various health benefits such as antibacterial, anti-depressant and anti-inflammatory qualities. The potential market for fresh turmeric includes both culinary and health buyers.

Turmeric needs 11 months from planting the rhizomes to harvest. In temperate areas, therefore, it has to be grown in a greenhouse or high tunnel and protected from frost. It should be started earlier than ginger, and it should be left to mature longer than ginger for the highest medicinal value.


Daniel Kelly of www.HawaiianOrganicGinger.com supplies seed rhizomes for both ginger and turmeric. He advises that turmeric “is a little shyer to sprout” than ginger. “I recommend letting the rhizome dry out 5-10 percent after you receive it. Then, when you put it into a moist environment, it will sprout. A higher starting temperature and letting it dry out a little before planting will trigger it to sprout earlier. You’re simulating nature a little.”


Turmeric also can withstand higher summer temperatures than ginger, he said. “It’s more like an eggplant compared to a tomato,” he said.


Turmeric looks different, too. Whereas ginger has thin, straplike leaves, turmeric has broad leaves, which can be used for wrapping fish or meat for cooking.


“The main difference in the growth habit is that ginger rises like antlers growing up, and turmeric grows like fingers growing down,” he said. “Only when it has filled up all the space downstairs does it spread.”


Kelly grows turmeric for the wholesale market, especially to health food stores across the U.S. He says that turmeric is less expensive to grow and not as finicky as ginger. However, it does require a little more work in harvesting and processing because the rhizomes are smaller and need more washing.


Bill Cox of Casselmonte Farms in Virginia sold 50 pounds of turmeric last year at farmers markets for $12 a pound. His customers were juicers.


“No one here has tried to develop a market presence but the health benefit has created interest. For 2016 we are expecting to grow about 100 pounds, so we will have to make some type of marketing effort,” he said.
