were do you live what zone are you in that would help us to help you to know how to take care of your Banana and do you know what variety it is? that would help to after you plant a corm and water it throughly its best to let it dry out a bit this encourages root growth if you keep it to wet it will rot so when the top 2 or 3 inches of the soil dry then you can start to water it they don't like boggy soil just moist never wet and don't put it right in to the sun they need to be eased in to over a period of a couple of week to a month or so depending on your zone and the temps they tend to sunburn until they adapt don't fertilize it for the first 6 weeks they need time to recover from the transplanting and the firt. will burn the newly developing roots always keep the fertilizer at least 5" away from the stem it can burn the plant i have all my Bananas in pots to i just put the firt out at the edges of the pots when there in the ground the have a pretty big root system when you start to see roots coming out the bottom of the pot its time to repot it to a bigger one
