I just moved to the Central Valley in CA and planted tropical plants around our new pool. They have grown great during the summer, but what do I need to do to protect them from fall & winter? I have a Dwart Cavendish Banana that went from about 2' to 8'. It's planted in the ground. I tried to separate the cuttings-3 of them. Looks like only one might make it. Any suggestions for protecting the main plant or to revive the cuttings?
Also I have a Majesty Palm in a container that I had inside until summer, then I moved it outside. How much cold can it tolerate? Should I move it back inside? Any help would be much appreciated. Thank you.

when u separate pups from a mother (banana) use a long bladed spade and make sure you cut vertically right down the side of the mother...and close to the mother then when u hit resistance thats when u apply the pressure and u will hear a snap as the separation takes place, then and only then do you dig up the pup root ball and all and replant; also dont attempt this until the pup has at least 3 leaves on it and is around 3 feet tall. this may be the reason 2 of your 3 didnt take...and I dont believe u can save the two that haave declined...the majesty palm grows well in a large container, but is frost sensitive, not cold sensitive; as long as you dont have a frost you can move it outside., and keep in mind that majesties prefer being out of the direct sun....place it under a tree or nearer the bananas so its shaded somewhat...good luck and if anything else let me know....Nick
