In previous years, the birds have gotten my figs, so I bought a big net. Now we've had back to back days in the high 90''s, even 100's. Also little water. In years past, I never watered my tree and still got plenty of figs...for the birds. Well I went to check on my fig and saw massive fruit drop. I feel like if it's not one thing, it's another. Is it the heat, water or both that most likely caused this recent occurence?
