I would first plant a couple of fig trees,inground and check the roots of the end of the year,for nematode in soil.
Once you find out soil is void of Nematodes then you can invest and plant as many trees as you want.
Here what I would recomend for your area:
Adriatic JH,Atreano,Mission,Marseilles vs black,Hardy Chicago,Sal Corleone,and Gene strains,Bataglia green, Gino's fig,Malta Black,Aubique Petite,Violette de Bordeaux,Kathleen Black,Lindhurst Wht,Paradiso,white bronze,and Nero(black),LSU Gold,Scott's black,Improved Celeste,Weeping fig,Sicilian Black,Stella,Tacoma Violett,and White Texas Everbearing.These are my best producing,best Tasting,from at least 150 cultivars tried to this date.
Of course there are others,but these are what grow well for me,and I think it will grow well for you.
