Hello,
My brother and I just picked up a Dwarf Giant Banana plant each from a local nursery on a whim a few days back. I was so distracted by my two little girls that I didn't notice how the leaf tips are curling under. Is this anything I should be concerned with? I know with other plants it's usually a sign of distress.

Also, would it be a good idea to separate the three right away, or should i plant them as is?

Thanks
Ryan
