Long story short, in the winter it has to be carried up to the third floor where the South facing windows are not very big. It has gotten too wide for the staircase between the 2nd and third floor. And it has not produced fruit, but that may be my fault. I don’t know how to prune, and have just reduced width so it fits through the door.
The ideal future home will have large South facing windows on the 1st floor. This is what it loked like when it was brought indoors last October.
