Huh, that's a new one on me Daisy. My fig tree makes a spring or "breba" crop on last year's wood, and a fall crop on new wood that ripens before the leaves drop. But we do have a very long season.
Anyway, if his fig has fruit right now, it also has leaves and needs sun. I think that's the priority for the next 9 days until he can give it to the lucky recipient.
My tree sucks up gallons of water when it has fruit on it, but of course it's in our sandy fast-draining soil so never gets too soggy. If it's going to be grown in a pot for a while don't you think that rocks in the saucer rather than in the bottom of the pot is a better idea?
Here's a whole thread on fig trees, but it's mainly chat about people who have trees already growing.
