banana tree leaves
I have an indoor banana tree in southern Michigan. I get sprouts but the leaves won't open. The first one eventually bent and broke and now I have another large one that didn't open with a second shoot coming up.

These symptoms can be caused by quite a few things, depending on how the damage and symptoms appear, and exactly where.
The most common reasons are overwatering, underwatering, low humidity, too much light (not likely indoors), not enough light, root rot, overfertilization, Ph imbalance, among many other things can cause banana's to act up.
The MOST common issue with indoor bananas is overwatering. They need the soil to dry down to at least 3 inches between watering, and need a container with PLENTY of drainage to allow all extra water out.
