Kelly, how do the tuber fare, when the greens are harvested a lot?
Are they puny, or are their just fewer of them?
Do you ever feed the bunnies the tubers?
Have you fed them dried stalks or leaves?
I tried growing them in pots right in front of the porch, specifically as treats for the bunnies, but they struggled.
I haven't checked the yields yet but above ground, they were sad looking, I'm not sure why.
I live in quite a cold climate, with frost possible any time of year. I have never, under any circumstances, gotten a sunchoke to blossom. I have gotten a few to grow about 6 feet high before they froze. I've tried them in every microclimate on my property and they definitely prefer very protected, south facing spots with very nutrient rich soil (bunny poop for the win!) But even the plants that grow the best produce very little in the way of tubers - I think it's just a little too cold here for them to thrive that way. The plants that I cut early seem to spread out sideways and produce even better greens, with multiple tiny tubers. The plants that grow tall all summer produce a single very thick, tough stalk that the bunnies still eat, but they definitely prefer the more tender leaves.
I have never fed the tubers to the buns, as sunchokes notoriously produce a lot of gas - at least in humans - and rabbits are rather famous for dying from gas, so it wasn't worth trying. I have never fed dried stalks or leaves - in the fall here they freeze, then wilt and rot. And if I'm cutting them, I'm just feeding them to the buns right away - I don't want to go to the trouble of drying and storing. The nutritional analysis posted above re: dried vs fresh was very interesting though.
