Beginner Gardening: How do you prune a schefflera (umbrella plant)?, 0 by MBoose

Hi,
I live in San Diego, CA and have schefflera planted in my yard that has become overgrown. It stands about 15' tall and is at least that wide, and has 13 trunks. I have read in previous posts that now is the time to prune it, and that making the cuts anywhere on the trunk is ok as the cuts heal quickly. However, I'm still concerned about goofing this up. We want the plant to remain "bushy", but not so tall and not so wide. To get an 8' tall by 8' wide plant, where should we cut? While some of the trunks are easy to identify as growing out of other trunks, I cannot pick out the "mother" trunk. Could there be more than one? I have added a photo that shows the trunks.
I'd appreciate any recommendations before this thing becomes any more unruly!
Thank you!
