bananas under coffee bush
Hello, this is my first post here. I'm moving back home to Knoxville after 4 years of being away and can't wait to get started gardening. I'm a complete newbie, but many of the cold winter days up north have been spent reading and daydreaming about growing edibles. Right now my plans are rather fantastic. I'm hoping to put up a cheap hoop tunnel with PVC pipes and plastic during the winter and just take off the plastic during summer.
Okay here's the question. Has anyone tried growing coffee bushes and bananas trees in pots in similar conditions. I've read about growing coffee as a house plant, and I've read some varieties of banana can be protected during winter. I'm just curious if anyone is doing something like this in zone 7. From what I've read the coffee could appreciate the partial shade underneath the banana. I guess what I'm really wondering is would the passive greenhouse conditions be adequate to protect both plants in winter or would I have to bring them inside?
Any input would be really appreciated.
