I bought this plant at a local grocery store at the end of May. I am very happy with it - it just keep growing and growing! It has tripled in size since May. I have repotted it twice and keep it nicely watered and in a sunny window, but I want to know how to keep taking care of it as it continues it's transition from small house plant to tropical tree! I have no idea where the identification tag went from the store, so please help me identify it so that I can figure out what to do to keep it alive and healthy throughout winter. I'd also appreciate any tips about making sure the main stem stays strong; it only has a slight lean but I'm getting more worried as it gets taller. Thank you, Sarah
