Re: how big does my greenhouse need to be?
Windsor is a lovely town- at least it was in the late 80s, when I lived in Detroit. I used to row on the Detroit river and look at all the houses and neat yards in Windsor- so many ancient, huge trunked Magnolias.
One of the worries with keeping plants in the greenhouse during the summer is heat. You just can't believe how hot it gets in there. My greenhouse is 24 ft x 36 ft, has double wall polycarbonate, has 2 doors at each end, has 4 foot vents running the length on each side, and has a 2 ft vent running along the roof. Even with all the doors and vents open, things cook in the greenhouse over the summer- it gets up around 120 degrees or even higher.
Putting a shadecloth over the top can help a little, but it will still get hot-hot.
As far as I know, the leaf span on Dwarf Cavendish should be up to around 6 ft.
And it's true what John said, no greenhouse is ever big enough. You'll build your GH, then want more citrus types, more bananas, start adding a few tropicals... LOL
Good luck! And welcome to the board and to bananas, I'm pretty new to both too, but completely addicted!
