The tree was starting to go into dormancy for the winter, but there were still several dozen small, green figs left on the branches. So on a couple of branches, I removed all the leaves to see what would happen. And guess what - the figs started turning colors!! But, it's just too cool right now for them to grow to full size and fully ripen. I wish I had seen this video a couple of months ago.
Next year, I'll give this a try much earlier & get all those leftover figs!
