Michael,

For the remainder if the season, water the trees when the growing mix begins to dry out.

If you intend to keep the trees containerized, you will need to periodically do root work on the them. The longer the trees stay in a container, the harder the root ball gets, and that is not good for the tree. I bare-rooted a Mission tree earlier in March which had been in its container for at least three years. The root ball was so hard, when I tried to push a chopstick into it, the chopstick went in about a half an inch before it met with so much resistance it broke instead of going in any further. I had problems giving the tree enough water as it would just run down the side of the container and out of the drain holes. When I did get around to bare-rooting, it took me almost 3 hours just to get the old growing mix out.

If you use a peat based growing mix, you will want to bare-root the tree more often than if you use a bark based growing mix. Peat breaks down faster than bark, so it looses it's structure and the growing mix collapses sooner.

There has been a lot written in the forum about the issues surrounding growing fig trees in containers and the many different ways people have solved them. A quick search should provide you with some answers to your questions.
