Ahh, makes sense. We haven't tried onions and garlic yet, either. I think the turmeric is supposed to be put in the ground early spring? I'll have to look it up again, but I believe that's what my boyfriend said. Apparently it will just stay dormant over winter even if you do leave it in the ground during the cold weather.
That makes sense. The ground here doesn't really freeze during winter. Maybe the first 1cm or something.
