That is until it goes into a grow bag after the holidays.
My observations so far about stone pine. When you pinch the growing tips a bud will pop near the pinch site. A lot like a JBP, except only a single bud instead of a whorl. Pinching the tip doesn’t seem to stop it from wanting to elongate. Seems like the strat is to allow the branch to elongate and then cut back to a bud. It pushes buds in an alternating pattern all along the branch.
It also seems to be a bit basally dominant.
