How To Make Annuals Into Perennials?
I hope that title catches someone's eye! Here in S'ern Wisconsin dwarf bananas are sold by the finest garden centers to be used as annuals for the uber chic like me ;) to get the tropical look in the dairy land.
I know nanners are really perennials and would like to experiment with carrying them over to next year. I could do a gray, dark windowsill approach but would rather not if I could get around it.
It's been suggested to me that the plants can just be cut off and stored cold over the winter and restarted in spring. They're currently in #1 containers. I have a cold storage room that stays around 50-55F most of the winter. Can I do this? And if so, what are the technical details?
Thanks for any help!
