Fig varieties are very important for Breba or main crop.
I got couple 5 ft tall fig trees in 2G pot from nursery last spring, I planted them in ground at sunny spot, one month had passed, no breba figs, I went to same nursery, All potted fig trees in tiny pots with slow release fertilizer was full of figs.
Steve(Fignutty) is right, If you rootbound fig trees with high dose fertilizer, it will give u lots of breba.
One year had passed, in ground fig trees did not top grow very much even with some compost/manure, about 1 Ft more canopy without breba/main, I wonder why?, I planted my fig trees in 6Ft x 6Ft raised garden, I opened one side panel of raised garden, it was filled with full of roots, it put highest portion of growing in its roots.
Spring has passed, no breba fig again, many fig trees was top killed by cold winter's wind, In ground tree with lots of roots or root bound in raised ground, They put all their energy to grow branches instead of breba, it put on 2Ft new branches in one month while non top killed in ground tree, they put on 5 inches new branches with breba.
