There seems to always be some confusion about pinching, it can be used for both increased fig production (in warmer zones) and for earlier fig production (in colder zones), I posted this explanation in an earlier topic...

"Pinching is used in conjunction with rubbing out buds to slow vegetative growth and limit the length of a fruiting branch. The tree then puts its energy into the figs. Its basically rubbing out the apical buds.
Pinching also induces branching just below the pinched apical bud (which is why rubbing out is required along with pinching in colder zones) you can easily create new fruiting branches near the apex of a branch, by Simply pinching the apical bud and allowing the new buds that form to grow into new fruiting branches.
The # of leaves refers to two things, the # of figs that can be produce and the amount of time that has passed in the growing season. If you are looking for more figs and more fruiting branches, pinch early, less leaves, more fruiting branches will develop early, and if your season is long enough more figs will be produced on the newly formed fruiting branches. It takes approximately 4 months for new limbs to form and ripen figs, so you can easily calculate the best time for pinching.
BTW, Personally, I prefer Pruning to create main branches, scaffold branches and fruiting branches."
Part of the confusion is that many posts on pinching for colder zones usually leave out or do not explain the "rubbing out" of newly formed buds (shoots), as Martin instructed in his earlier post #21.
