im in a similar situation with a potted cogshall i have. it has 2 lower branches coming out from 1 point on the trunk, but at around the 5 foot mark it has maybe 6 or 7 branches, many of those branches have already split and are giving 2 to 3 branches, if that makes any sense. the tree as of now looks like a lolipop, with a bare trunk then tons of growth at the very top.
