How well do Banana trees do in pots?
I have a friend who recently moved form a house to a tiny apartment and I am babysitting her banana tress. She chopped off the trunks to about 2 feet high and then dug them up and stuck them in pots ranging from 5 gallons to 10 gallons. They have been in my care for two months now. Initially they looked great, made lots of new leaves and several babies came up in the pots too. Lately the edges of the leaves are a little brown, and they just don't look happy. Also, I noticed the leaves fold up during the high temps or direct sun. I assume this is a normal defense mechanism to help prevent water loss from leaves. We have had some really high temp days in the last month out here in the central valley of CA and I have tried to keep them well watered. We also have some pretty strong winds that tend to rip the leaves. I have no clue how long I will have to keep them. They are currently 4 to 6 feet tall and many of the leaves are 30 inches long. Do they need bigger pots? Should I dig out and repot the babies? Can they stay in pots indefinitely?
Any advice would be appreciated.
