Callalily in Pot/Freezing
I have two Callalilies in nice clay pots under the coverd patio next to the house wall. The temp here can get as low as 18. Do I need to protect their roots/bulbs. After 7 years of trial and error(had to transplant from the yard) I have finnally got them to grow really big. With summers in the 100's(cooking them) and winters in the low 30's its been tuff but I think I have a handel on it now. I would if possible like them to keep their leaves over winter. What can I do?
