Re: caladium low temp. was: picture

According to all info. I have ever found, 60F is as low as they are
happy with; temps in the 50s can injure the tuber.  So, you need to
wait until your night time lows are around 60F before you put them
outside.  It's not that they will actually keel over at 50F, but they
will suffer, which means they won't grow as well for you.
