Re: over-watering vs under-watering ?
This time of year it is easy to over water, any house plant. Banana's are one of the easiest. Make sure your pots drain well, lighten up your soil with perlite and let them dry out between watering. Banana's will grow slow or not at all this time of year. They may not look as good as you like them to look and many are killed with kindness. Most of mine are stored bare root and get no water from the middle of Oct. - the middle of May.
