There is a reasonably thick bark mulch, but I think it is mainly the black plastic of the pot heating in the sun. Some folks who grow figs in pots paint the pots white and that makes a big difference in soil temperature. I'm going to try that, or wrap something around the pot that shades the black plastic sides.

I did find an article that mentioned soil temperatures over 95F by midmorning causing blossom drop. I don't think I actually have that high a temp that early in the day, but certainly by later in the day I do.
