This sweet potato was grown in the same area I live in and weighted 16 pounds. I wish I knew this person so I could some suggestions on growing them here. The article mentioned they had good soil and used this certain type of fertilizer. I have added a lot of compost and manure to my soil so it is getting very loose and I try not to walk on it since I use a version of the French Intensive method. Well I guess I will try again next year and see what I get.
