When they get soft and droop, I tug. Nothing happens, next day, I tug again. But I will say, if they get too dried and droopy, the birds can have them! I like a ripe, juicy fig. So, if the fig still hangs on, and I see droop and wrinkles, I go commando! I rip it from it's stem, and it works out just fine!
Not a fan of figs dried on the tree.
