A while back, I asked here for help with my fig tree, which, while
pretty
good at producing leaves, wasn't too hot at making figs.

The concensus then seemed to be that I needed to water the fig tree
regularly, and feed it with liquid tomato fertilizer...

Probably better to starve it than to feed it !!
Plants tend to produce fruits and seed to survive if they feel
threatened ~)
Besides they grow in really poor soil in the wild........
Restricting the roots will help too.
