I have a fig tree that is about 4 years old. I think I put it in the ground in summer of 2014. The first year, it shot up straight and tall with no side branches. I tried pinching it, but it always grew right back out of the top or just below it. I tried bending it over when it was still young enough to do so, but no branches. Last season, I headed it back at least three times, cutting off several feet on the leader each time... but still, it grows taller. I even tried scoring a line just above nodes where I wanted a branch. Nada on the lower part of the trunk.
I am convinced that this tree will never make lower side shoots on it's own. In this picture, you can see where I made a drop-crotch cut just above the lowest branch. I would like branches to begin at around 18" from the ground. If I am unable to get a branch to grow on the lower part, would grafting be a good option? The tree is now 5 feet tall and is about 1" diameter where I made the cut on top (so I guess max. caliper is around 2"). What type of grafts would be best to make scaffold branches? Will grafted branches be strong when the tree is mature? Where should I place them? What time of year should I do it? I don't need a lot of detail, but I would appreciate a shove in the right direction.
If anybody has a technique to make side branches without grafting, I'd love to hear that too. But, now I am sort of excited about making a Frankenfig.
