[Marj]

marjschneider@bellsouth.netPlanning is under way for the Southeastern Citrus Expo,being held in Savannah, Georgia  at Skidaway Island State Park on Saturday November 18, 2017. We are looking for someone to speak on growing citrus with organic methods. If your trees fruit consistently and you've been able to address problems successfully with organic solutions, other growers need to hear from you! If you are willing to share your knowledge and experiences and can come to Savannah in November, please contact me. We'll buy your lunch.

I think you need to define this question a bit more, where I live in SW Louisiana most people that I know with in ground home citrus (mostly Satsumas, but also some others)  do nothing for their trees, no fertilizer or care of any kind, they just pick the fruit each year.
