Any chance of a slight frost hitting it? I guess if the problem started in summer NOT just recently that would NOT be an issue. Maybe you should try them in the ground next year, if you can. It COULD be that the pot is too small. Yours look much smaller than they can potentially be from planting to the end of the growing season. They do fine when the roots are dug up and stored in a cool not cold dry area to overwinter, so, maybe if you just let the plant die back outside just enough for the top to die down, then keep it all as is in your sunroom, if it doesn't get too warm in there, and try next spring to pot it up in a pretty huge pot and see if that is better. I am GUESSing at all this. Maybe your sunroom will be so warm that your Musa may NOT go dormant. Putting it out to make it go dormant, should help. But, I am not sure if once you have it in the sunroom it will then, sprout up new growth. IF the sunroom stays kinda cold in winter, it MAY stay dormant. I am GUESSING that it may be fine staying green in a sunroom in winter, BUT, the shorter days may make it go dormant anyway. I hope you get a better answer than mine. Later, and good luck. BTW, in ground is best if you can.

Was the bread a yeast bread or a quick bread? There are recipes for Yeasted Banana Bread (including some recipes with dried fruit in them - more like a banana-flavored raisin bread - King Arthur has a Sandwich Banana Bread recipe). There are also recipes for Banana Bread Pudding with Caramel Sauce. Perhaps with a little more searching you can "marry" two recipes to get a copy-cat recipe. I've made bread pudding using an over-baked loaf of banana bread that was too dry. Too bad I wouldn't have thought about adding the caramel sauce..... :-) My go-to recipe: Palm Sugar Caramel Sauce (2 servings) 1/4 c. palm sugar 1 T. half & half 1/2 T. Lyle's Golden Syrup Cook and stir 2-3 minutes in a small pan (or in a small bowl in the microwave for 1-2 minutes) until smooth and caramel color. Add chopped pecans, if desired. [I pour this over chopped fresh apple bits and top it with granola.] -Grainlady

Is any part of Turkey a Zone 10? If it is a Zone 10 could be ANY banana species.

Nick I have an apple banana but no pups yet. There are a few small bananas out there. Truely tiny is supposed to be really small. Musa Basjoo is supposed to be really cold hardy. Also you can probably just put some old school christmas lights on them during the winter. I've heard of people doing that.
