I've grown them a few years, they're easy.
For winters, after the second year they grow huge underground, when the shoots die back just dig them up and put a bulb with a knot back in the ground for 2 years later. As long as it's below the frost line it will be fine. You'll lose a few every year, but once you get them propagated out you'll never run out. They're reasonably resilient plants.
It's pretty easy. Our yeild was not huge, but they will take a fair amount of negelect (leaving it out in the sun when it's 35Β°C, or not putting it back in the sun on days when the high is 20Β°C, forgetting to water it, overwatering it, etc.).
12b, so a good place for tropical plants, but I still get freezes and the south is generally a good place for most hot weather plants. If you're up north you'd need a greenhouse for turmeric.
