I have been looking around the site at some of the different posts about cold hardiness. It is starting to get cool here in central Ohio with forecasted highs 65-70 and lows 48-55. I have a gran main (26 inch pstem) 2 dwarf cavendish (18 and 13) and a 12 inch dwarf ladyfinger. Would you bring these inside at night to avoid leaf damage?
On a side note, my indoor growing area will be ready in 2 weeks, so just trying to get to that point then I'm good.

I do not know at what temp. the leaves will be damaged , but you won't have any problems above 40.

They will surely not survive 0°C (32°F), so anything slightly above is critical.

I am no expert, but from what I read is to not worry about it until night temperatures drop below 40 degrees. as long as the day temperatures are in the 70s you should be alright. I would just be careful with the watering and watch out for rot with temperature below 50. I have a few bananas in the ground and a few in pots and they seem to be doing alright here in zone 6 (night temperatures in the 50s). If any other members could chip in, it would be great!

Outdoor potted plants holding their own in Conn. Got down to 48 briefly last night.

I've got a good variety of nanners in pots in Michigan, and so far so good. No damage and still growing well (it's been really rainy and cold all week). It's supposed to be low 40's the next two nights, so we shall see. I have the utmost confidence in these tough, little guys.

Yeah, I was kinda wondering about this as well. I'm gonna move mine all inside pretty soon, but I'm holding out for now. It gets into the mid to low 50's at night here but is in the mid 80's during the day. They really love all the sun they get during the day, so I hate to bring em in until I have to.

It is also makes a lot of difference in regards to the kind of banana you own and if the banana has a cover overhead and more so around it. Without any protection my banana leaves browned at zero degrees if the tempt stays overnight below or at zero degrees (32 degrees F. But it is safe to say that at 40 degrees or to 37 degrees the leaves would still stay green. By 35 degrees it is a toss-up.

This is what I meant for the kind of bananas you own.
On the far left was a Calif Gold and the far center where the leaves were browned was a dwarf Brazilian. Dwarf Brazilian is suppose to be one of the cold hardy bananas in zone 9. Both were left unprotected and were planted on the ground. The bananas in pots were stored inside my patio and came out unscathed.

I tried to post the pic here but it appears it does not work. I'll try again.

OK it works now.
Buckeye, I've been over-wintering for 3 years now (great success). I always reduce watering drastically when in the 50's at night & would never leave them outside once nightime temps reach 40's. Also, I lost a large mother plant when it sat moist below 50 at night for several nights.
