We grew Turmeric in Zone 7A!
One of the things I enjoy doing here is trying to see what exotic stuff we can grow on our own. Being in Zone 7 limits a lot of the tropical items to hot houses or changes them into annuals instead of perennials.
Last year I picked up some turmeric tubers from Andy's Asparagus Gardens and planted them in pots. We had two tubers in each pot, roughly a 1 cubic foot square planter. Here's how the harvest ended up:
Next steps? Figuring out dehydrating it and using it in our own cooking, and comparing it to the commercially-produced varieties. Often, certain temperature requirements exist to get certain flavors in plants. Next year we'll be running this in our greenhouse and overwintering it as well.
