Scuppernogs – Fertilization and Care
Q: Can you advise me as to a good fertilization schedule for scuppernongs?
A: For established vines apply three to five pounds of 10-10-10 per plant in March of each year. Apply one-half pound of ammonium nitrate in June. Grapes have a relatively high requirement for magnesium so apply two to four ounces of Epsom salts to young vines and four to six ounces to established vines each year.
