A while ago pretty much the two biggest branches on the left side of my Golden Gate Ficus just died. I believe it may have been because I had just gotten it and it was reacting to the change in environment. The rest of the plant looks fine and is thriving quite well, but it just looks horrible with no growth on the entire lower left side of the plant. Is there a way to promote new branch growth in that specific area of the plant? New branches have been growing at the top, but none where the dead ones were.

Any help is appreciated, thanks.
