I am in NJ and have just started on this venture this year - growing tropical fruits in containers - hoping to somehow keep  them alive thru cold NJ winters.   I presently have a few fig trees (about a foot tall), two pink guavas, two pomegranates,  and have ordered two dwarf papaya plants, and looking to add dwarf mango and star fruit plants.  I have much to learn about this and would appreciate hearing from anyone who has successfully grown such fruit in NJ or similar climate.   Thanks to anyone who can share some tips and insights.
