I am new to growing bananas, having just one large basjoo. I ordered eight plants and put them in new pots in the hoophouse for a couple of days. They were looking good, but the temperature was beginning to get down to 40 degrees outside at night and I decided to bring them in the house. Within 24 hours the leaves started to show dry, shriveled brown areas. I figured they would adjust. All but two have put out new leaves. I figure that one of the plants will be a total loss as the problem with the leaves spread until the entire plant was unhealthy. I cut the pseudostem and tried to take a look in the top, but it looks like it will soon be gone. But what I am really writing about is the other plant which has some brown areas on the leaves. This plant doesn't look any different than the ones that are recovering and putting out new leaves, except it is not putting out a new leaf. I have uncurled the newest leaf to see if I could see a new leaf coming, but there isn't one.

Since I am such a newbie, can someone tell me something about the temperature change which think is what started these problems? I took the plants from 60 degrees to 74 degrees. Please advise me about this.

Then, what do I do about the plant that is not growing any new leaves?

I am so excited about growing some banana plants, but they will have to be inside for the winter. I just have a lot to learn!

Thank you for any insight you can give me!

how hot does it get in your hoop house during the day? tc's are delicate.

i find my plants dont like the transition in the fall either
they look ok out in the cold and then once you bring them in they look worse for a bit
they will adjust...

Those are TCs and difficult to maintain because of their delicate condition. ... First, the environment of the house tends to have much less humidity (. Young TCs were being grown in a greenhouse with very high humidity (70 to 80%) &/or misting when you purchased them. Your hoop house helped to maintain a higher humidity (not as much as the grower's greenhouse; but higher) for the young plants.

The plants IMO, look to be over watered. The drier humidity of the house has caused the plants to dry out and their leaves droop. I suspect as a result, you've then water the plants. ... In the house these young plants just need misting of the leaves 2 or 3 X's a day. May be add a large plastic bag over the plant & pot to retain humidity.

Now, how much water are you giving the plants and how often? A little bit every 10 to 14 days should be plenty. The potting soil needs to dry out between watering. Over watering WILL cause root rot.

You can try letting the pots dry out. But, the TCs being delicate and do not have large store of energy (corm), I would repot with dry potting soil taking care not to disturb the root ball. After a few days give a little bit of water. But Mist the green part of the plant every day.

Also, be careful of placing the plant too close to cold windows. TCs can be very sensitive to cold and quick changes in temps.

Oh, the plants you state are recovering ... are not and in stress too!

I hope this helps. However, TCs when they develop problems will quickly become a loss cause.

Thank you for responses and encouragement. When I received the plants and potted them I watered them of course. Then they didn't actually go in the hoophouse which is very humid, but in a similar structure that wasn't as humid or warm. I didn't think about misting them when I moved them to the house, but that is a great suggestion. We live in humid Tennessee, but it is not so humid at this time of year, and certainly not in the house. I did repot the one plant that is dying (no picture of that one), and the soil was more than damp, but not wet (somewhere in between). All plants received a light shot of water a couple of days ago; otherwise I haven't watered them after I initially potted them. I know that these will recover except for the one (no picture), but I am concerned about the one that is not growing a new leaf. Do I just need to be patient?

yes be patient.

the reason your plants are browning at the edges [looks like] is they got either to hot or to cold. I have very good friend just east of you. you have had some nights in the lower 30's. might have got to cold in your hoop house/green house. your tc's are very sensitive, to much water to little water will set them back. also are way more sensitive to cold and heat compared to a well established banana.

Relative humidity is based on the temperature. The low temperature outside has a higher RE. Inside the house because of the heating RE drops to 40-50% during the winter, which is stress on bananas. Misting them daily indoors is an option, use distilled, low salts or rain water.
