Pics are below. The Superthrive may explain it. I don't mind if it keeps growing that way as long as it's healthy.
It's in typical bark and white sponge rock mix, in inland Massachusetts, always forget what my zone is. It's in a south-east window indoors. The window has an electric baseboard heater below it. It's about a foot back from the heater and window, with some other plants in front of it. I don't have anything for humidity. I'm looking to re-arrange so I can include a mist-maker in the vicinity, haven't gotten around to it yet. There's a certain matter of available plugs in the way.
Should I be peeling the whole cane? I tried to peel the purple sheath off the bent portion, but it tore the leaf at the end into two remaining pieces on the plant. Pics include what it looked like when I tried that.
Cheers,
Kara
