As pitangadiego mentioned, it depends on what shape you want your fig in. If you want more of a classic tree shape, pick on central leader and prune the others off. However, the fig will be harder to winterize if it gets too big. If you'd prefer a bush type, I'd pick 3-4 main branches and remove the others. This keeps them away from each other and the open portion of the tree open to promote air flow. You can have more or less branches as you wish. Figs produce their main crop on new growth, so pruning while dormant shouldn't reduce your fig crop. Late season, if it looks like the crop will not ripen in time, prune away the smallest figs, allowing the tree to put its energy into the remaining fruit. People will also tip prune. After a branch has put out 5 or so leaves, prune away the lead tip. This will promote branching but also fruiting is the theory. Can't say I had much luck with it this year, but I'll probably try again. You may also want to invest in an early season variety, like Chicago Hardy.

Joshua: Have you considered going with pots? I'm growing figs and many other fruits in a greenhouse. It's true that pots are added expense. But on almost every other front pots are better. They are way more flexible in that only bearing plants are taking up valuable space. Spacing can be changed at any time. Fruit quality is usually better. And yield will probably be higher because all the area has bearing figs at all times.

Price, There are many good fig forum members that MAY sell trees or fill an order for the right price depending on the variety. If you have done research and want a variety that is very rare or from Belleclares then the price should warrant that. A long time ago I wanted and BC Sals and paid in excess of ~$80-90 for it. I have seen a tree which I wanted badly (a Vasilika Sika) go for sale for $150. There are members here which I would proudly hand over that amount for a tree because you know that you are getting a tree true to variety and is available at no other nursery. In other words diamonds are priced like diamonds and pencils are priced like pencils. To many times people come on the forum after reading for a few days and decide they want to buy a rare tree an offer a very low amount of money for a variety that may have cost them $100+, not to mention the care that the tree took in order to get it to a point where it can be propagated. Buying a larger tree means also that you can enjoy figs anywhere from 1-2 years sooner that trying to propagate yourself. I hate to even talk about this because there is always someone who will come and flame this conversation because they feel that the trees should be practically free for what ever reason with out taking into consideration the care, rarity, potting soil cost, heating of greenhouses in the winter, etc. For instance some members have potting soil and other costs in excess of $50-$100/month. If you have a questions please feel free to email me and after asking some of the members or friend maybe I can refer you to them. Thanks.

I suppose it depends upon how many figs you want. I doubt that many figs will be produced this year since from the pic above it looks pretty much pruned down to dwarf size. I have 2 figs trees and both are about 12' tall which gives us plenty of fruit to make fig jam and for fresh eating. Annually I'll prune out the inner most branches down to ground level to allow more sunlight in and for better air circulation. But I do have the space for them and the branches are flexible enough to bend over for easier picking from the top. If your goal is for a compact ornamental look and enough fruit produced for snacks then your pruning method should fill that bill.
