@fiat, Happy to help but I am no expert. But I have been able to keep my ferns growing for generations. Boston Ferns are plentiful here in the South often going on sale in the spring for $5 a basket. I see neighbors treat them like annuals because they are so easily replaceable. I prefer to preserve what I have. But I think because they are easily and cheaply gotten here that I am braver about dividing, experimenting, and other "plant abuse". The Boston's always come through for me.
