So I've had this banana plant since september. For a while it was doing great, but recently it has started turning brown and yellow (also the new leaves and pups!) and I have no clue what's wrong. Here's what I do know:
-I water it about 2 or 3 times a week in the winter
-I recently fed it for the first time in 3 months (I'm so sorry i failed you)
-It's standing right in front of a West-facing window (try to give it as much light as I can)
-The air humidity is really low so I spray the leaves about once or twice a day.
-It gets pretty cold at night where I live

Please help me, and most of all my banana plant! I really want to keep it alive.
