Re: Hi !
Welcome from NYC! Im really bad at starting most plants from seed so I hope you have more luck than I do. I hear that Musa Velutina is one of the easiest bananas to start from seed so you might want to try them!
Im also a bit impatient when it comes to growing things from seed and banana plants are very slow to start from seed. If you can find pups, definitely try those. You will be more confident that you were given the correct species (sometimes seeds are not ID'ed correctly) and you will get tall plants much faster. I got a Musa saba as a small pup in October 2010 and now just 1.5 years later it is 9 feet tall and grows very fast during hot weather!
