apartment

In a few weeks me and my mom are gonna be moving to an apartment. Unfortunately the only place my pre-bonsai can go will be on our north facing balcony. (The trees I have are; 1 silver maple, 2 black cherry trees, and 2 pin oaks) I'm from NE Ohio so north facing isn't great. They'll be moving...

Just moved to a 15th floor apartment with an east facing balcony in New York. Would love to add some trees (have my eyes set on a maple) but I am concerned about wind damage and proper wintering. I have been reading these forums for solutions but it looks like most people with similar questions...
