it might need old cow or horse manure and another fig tree near it..is something eating the figs.............after the sun goes down mix up 1 teasp liquid hand soap and 1 qt water and spray..............if you could put black deer netting over it...they have it at walmart lowes and home depot in the fall do the fertilizer......and spray with dormant oil..............use old clothes, gloves, mask and goggles & hat and spray everything as that would smother any eggs. Did you look at the dropped figs....any bites taken out....some bats will eat fruit, so will some birds and other wildlife.
