A couple years ago, some giant Calla were offered through this group. I
purchased a few. Two years ago I kept them growing indoor over the
winter. Last year I just couldn't get enough time in the fall and the hard
winter hit them harder than I would have expected.
In July I found some tiny Calla shoots and by this fall I had small plants
growing. Another winter like last and I'll lose them
altogether. Consequently, I'd like to keep them inside this winter. Space
is limitted so ideally I'll store them as tubers (or corms, if that's what
So with that in mind:
Can I store them as tubers over the winter?
Some tubers are best washed of any soil and soaked in fungicide before
storage. Others do better just being left with soil clinging to the
roots. To which group do Calla fall?
Some tubers do best stored at 45-50 degrees. Others like Caladiums need to
be far warmer. What temperature would be best for Calla?
Should they be stored dry or packed in perlite or could this be a good use
for the endless supply of foam packing peanuts?
