Hi Saskatoon,
Welcome to the forum !
Did you water and fertilize your trees ?
If those spots do lack water, fertilizer and/or sun, whatever you plant there is doomed to fail ...
BT droping figs ... I want to see that ! So you just had some random unknown fig ... Sorry for that bad experience ...
Are you in a standard Californian Zone, or in the coldest part of California ?
In the standard Californian Zone, provided that you water the trees, you should have great harvest whatever you plant.
But, stick to the known and well tested strains. Col de dame Gris, noir, or Blanc - Noir de Caromb - Preto - Black madeira - one of the whatever BT (BT, Califonian BT ... ) , Desert King , Longue d'aout ...
You have a lot of choices ...
Definitively, take the time to drive to one nursery and choose the tree yourself .
