I have a Brown Turkey fig. It's about 8yrs old and hasn't really grown a huge about because of the 'die back' each winter. This was the first yr. I got lots of figs. It has lots of branches/suckers but is only about 10ft tall..

When and how do I prune it properly? Do I need to cut out all the suckers in the center and leave the outer ones. It had these suckers when it was purchased...That is why I call it a bush instead of a tree.. Thanks for any/all help.
