I live in the Central Valley in CA where nights have been getting down into mid 30's. I have a Dwaft Cavindish Musa that grew in the ground to a height of about 7' this year. The label that came on it said it was good to 25 degrees. Since it is in the ground, I can't bring it inside. I did spray with Cloud Cover, but it's too big to cover( I tried). Any suggestins to help protect it? The leaves are turning brown which I expected, but i really would like to have it come back in the spring and maybe produce bananas.
I also have a plumeria tree which is in a container & I have brought that inside , placed in a dark room & am allowing it to go dormant per instructions in readings on the web. Any suggestions for it?

Thanks. LindaS
