No it wasn't on a window an it has only been out when it has been warm enough 50-60º and yes the roots look healthy thick and white and ya our winter was awful here to

an I only have the two a basjoo an orinoco but I'm hoping mayb I can get some pups off of them this year so I can see if they come back next year an like u said if not I will at least have pups I really don't care if they fruit I just mainly like the look and want them all in ny yard lol

) but I don't have a lot of space inside for them so they have to stay outdoors unless they are smaller . I can't believe you are raising so many in zone 4 wow that's amazing because I know it gets cold here I'm assuming it worse there though!
