Hello all. I am new to this, so bear with me a little. I have read a lot of great information here, but still have a few questions.

I am a high school science teacher with a greenhouse attached to my classroom. I am in Illinois on the border between a zone 5 and a zone 6. I have purchased 6 different varieties of bananas. They are all small at this point (12-30"). Some are cold hardy (basjoo), some are not (ice cream, mysore). All the plants were transplanted into 8" pots with a soil mixture of dirt, peat moss, and sand.

Can anyone tell me if I am on the right track? The plants will get a reasonable amount of sun and the temperature and humidity will stay high. How often should I water and fertilize them? Can I expect growth during the winter in the greenhouse?

Any other thoughts or suggestions?

Thanks,
FW
