Fig Fruit, Growth Static

Question

My wife has a fig tree that is planted in a container 900 mm in diameter. Last year it produced a small amount of fruit; however, this year it has produced much more. . . BUT the fruits’ growth is static. Currently the fruit is between 15 and 25 mm in diameter, and they have remained so for the last 3 weeks or so. We live the Algarve, Portugal and the tree is watered every second day. If you could make a suggestion to get them growing, she’d be most appreciative.
