We live in a flat and our plant is in the lounge, although we moved it to the bedroom. Over the winter the banana behaved well, especially that the room temperature wasn't too high, so I guess the latest outside temperature jump had caused some major change in the room temperature - especially that we live on the top floor and a typical summer day is very very hot. I am not sure how could I provide more humidity for the banana and wondering if often water spraying the leaves could help a bit? It looks like in a short period we will have a handful of plants, as after separating and moving the 2 plants to a bigger pot, we just spot that another 2 small bananas appeared to grow from the side of the large: that is now 4 plants!
