basjoo size for leaving outside?
Ok, so I've read everything I can get my eyeballs on about overwintering basjoos in a cold climate. But I don't recall reading at what size they can be left out...any size? I'm in southern WI, zone 5. I have two, with 6 pups. I'd planned on bringing them in this winter....letting them (hopefully) grow a little more, and winterizing them and leaving them out next winter and beyond. However, just out of curiousity, is there a rule of thumb on height, number of leaves or diameter of P-stem as far as winterizing them outside in cold climates? They were pups themselves this spring.
Thanks!
Angie
