I live in Zone 8. Do I need to dig up ferns to overwinter before frost? They are doing great, and I would hate to have to remove and pot them. Any special care required if I can leave them in ground? Also, I planted some astilbe from bulb this spring but none have flowered. They are planted under a persimmon tree. Plants are only about 4-5 inches high! Did I plant them too deep?
