Last year I attempted a bud graft of an orange cultivar onto a grapefruit tree. The reason I did this is because the branching higher up is weak, leaning, and just a matter of time till snapping.
Unfortunately, I had to go overseas for a year, and just now have inspected the graft. I did the large rectangular piece for a grafting lower down on tree. Nothing ever shooted, but it still appears to be green and alive. If I were to prune all the growth above the bud, would it start to push growth from the bud? Though it is heating up for summer in Australia, this new growth would be in the shade due to other branches on my multigraft tree.
