Advice for potted Banana
I'm up in southern New Hampshire. I recently took over my father in laws indoor plants. I set up some grow lights and rearranged things in the east facing solarium. He bought a pretty big potted banana tree in the late summer and it's been inside seemingly doing well since he bought it.
I have it by the window and I water it when it dries.
It has been growing new leaves regularly, they open very beautiful and a healthy green but yellow quickly then wither down to the trunk.
As they wither completely, should I just let them go or should I cut them off?
Along with some general tips, could you tell me what could be going wrong with the leaves?
