One more thing to make sure we're all on the same page. The plants that I 'liberated' are grown from rhizomes, not roots per se. But that might not be true of all Aspidistras and y'all might have known that anyway. I'm throwing this in b/c I was getting confused by the use of the word 'roots'. But that could be me.
Anyway, best of luck. I think most places have Master Gardeners. And I often go to certain nurseries just to ask questions. Ya never know what you might find out.
