Bought this plant this past end of season at a local big box store on clearance. Name is presently escaping me but it like a Coral Bells, seemed hardy and robust at the time I purchased and best it could grow in a container in shade. Was just out looking at it and the leaves seemed a big crumbly so when I touched it the entire top MOVED and came off! THEN I could see FOUR off-white curled maggot bugs that have seemingly eaten off all the roots! Anything I can do to save the plant? There are still a few hair roots on the outside of the root ball. Any idea what to do too to get rid of these maggots? And should I be treating all my containers (ferns and hostas in the others) Any help would be really appreciated.
