Hail Mary-
Welcome aboard the Banana Express!
I really think you need to consider making raised beds in your garage and adding grow lights. Bringing that many plants in and out every season is going to get ever harder each time. If you have an open (two story) foyer, you might consider putting the palm in there, along with a few of the bigger banana varieties. You have a LOT of work ahead of you, LOL.
Sorry it took me so long to welcome you. I'm just now getting around to catching up on all the welcomes I missed while I was gone. BTW, I'm glad you decided to stick around.
