just an FYI
this isnt just for figs.
i tip-prune (pinch) the tops of my guava
it makes it develop 2 shoots instead of 1
so, it is forming the shape of the tree, as well as putting some of the energy into fruit instead of new growth
i do this on a regular basis with guava
but, also do it with Jujube, Mango, loquat, barbados cherry etc...
some trees like Barbados Cherry (Acerola / Malpighia emarginata)
can have long skinny branches which will bend with too much fruit on them.
tipping the branch when young will keep it shorter so the branch will bend less under the weight of the fruit.
it will certainly change the form and shape, so keep that in mind, especially for something like mango.
you can see the tops, which were much longer, now forcing new side growth on this Acerola / Barbados Cherry
and here, forcing fruit on the laft, and flowers on the right.
long skinny branches ... normal growth before tip-pruning
