@bluepoppy, I have probably grown well over 200 fiddle leafs over the years and have several dozen as we speak. Given time, your fiddle will branch. This is a tree. But it will take several years. I cut my tallish, spindly plants back all the time, both to keep them shorter (I can't ship a plant taller than 3') and to encourage branching. If I had a 5' tree, I would cut it half-way up. Strip off the lower 3/4 leaves from the upper section, apply rooting hormone to the cut tip, and stick it in a pot of soil. Keep it warm and constantly moist. It might just root for you.
