Q.Why Have All My Purple Muscadines Turned Green When Maturing ?
My original Muscadine plants(three of them) were purple but someone gave me a green muscadine plant and now for the past two Harvests they are all green . I have at least two self-polinating plants and I want only purple Muscadines , is there anything I should do during the off-season ? thank you , Brent
