That does make sense, limiting watering of your banana plant Cinta during winter when indoors. But once outdoors, I would think the banana plants would enjoy more moisture.
I almost killed my first Sans, did not understand how it hates being cold. I was growing it outdoors in a container and even my container was wrong, I should have removed the lower part of the self-watering container, so the base of the leaves were rotting. Luckily, caught it in time and have carefully nurtured it back. But now I know better, so I just have all my Sans indoors, by my west facing window in a very well draining media and in a container with good drainage. They get dappled light since our house is shaded by the city trees in the afternoon. During summer, I can freely water them, but when cooler Fall temps start to come, I start slowing down in watering them.
