cold tolerance of elephant ears and bannana plants.
In my basement I have 12 pot's of emephant ears and 5 bannana plants in pots.
They all survived so far !
I would like to move them out side and have a shed that I built with a poly roof.
It warms up nice but cools off quick when clouldy or at night.
I can put a small electric heater in it at night but don.t want to go broke heating it.
I thought that 50 degrees was about the lower limit for elephant ears and bannanas
. The bannas are a dwarf cavendih,red leaf and 3 Musa basjoo.
Do I need to harden them off?
