I'm still unsure of what to do this fall. Last fall, I wrapped the stalk in bubble wrap and then covered it in plastic. It went limp in late winter, but it shot up new growth from the ground this summer. I'd say the new growth (lots of pups) got to 3' max. So I bought a new Basjoo and it's done very well this summer. About 6' tall anyway.

If I bring it in, it'll go in a dark basement storage room. It's not especially cool in there, but probably remains in the lower 60s to upper 50s in winter. That's where I store all my Elephant Ear bulbs in bags in winter, and they do fine.

Other option, try wrapping again, but wrap insulation around it, then cover with plastic. Last year it froze in early November, so I chopped off the top, sprayed the stalk with fungicide, and let it dry out for a week or so before covering it.

Any suggestions from an expert? I'm in Denver, and it typically gets down to 0 or a little below at my house. Last winter the coldest I got was 6 above.
