This year i planted three rock ferns under a shady hedgerow facing north east. They receive a little dappled sun in the morning but are in shade most of the day. The soil is moist, but not waterlogged as there is a land drain nearby. Only one seems to be thriving. One is nearly dead and the other looks sickly. They only have one or two healthy looking fronds with the others having brown edges or totally brown. They ferns were bought from a specialist in plants for shady places.
