We have a Dwarf Red in Florida Z9b. We don't take chances and put a simple hoop house over all our bananas when the first low temps threaten. It's not complicated, expensive nor does it take much time really. In Florida, it generally only gets into the 30s for brief periods of time, so it is not necessary to over-engineer the tent. We put a light in there to knock off the chill when necessary.

In March after the last frost date we remove the hoop house and our bananas are ROCKING beautiful with hardly any detectible damage. In this way, we don't really sweat what exact temp will hurt which specie and when. It is so worth the minimal effort come March b/c our garden gets a big colorful boost from the still green bananas, so happy to feel the warm weather return.

As I write this I cannot find the pics of our tent to attach, but if anyone cares I can seek them out on another computer and post them later. It is your basic hoop house assembled with a plastic electrical conduit skeleton and plastic sheeting held together with .99 cent clamps.

In any event, I hope your DR survives for you and I would be interested in knowing how it does without protection should you choose to go that route.

Best regards
