I realised I had updated a bit on the ground grown pines, but not those solely developing in pots, so here's a few pics of some of the JBP that have been 100% in pots from seed and a bit of a description of what my intentions are with them going forward.
Nowhere near the size of the other ones, but still developing pretty well I think.
A few of them on the bench ...
A close up of the base of one. I have decandled this last December to keep growth in close to the trunk while the sacrifice lengthens to add a bit of girth. This one was wired early for movement.
This one I am taking a different route ... will probably end up with a smaller tree. I removed the sacrifice a couple of months ago and will be focussing on refining the top from here. No movement was wired in so the trunk is quite straight, but I think a change in planting angle and a new leader jutting off for the apex will give it the interest and taper it needs. I'm thinking I should get something more resembling a bonsai in a year or two... maybe 3.
This last one is 2 seedlings that have been grown together since they were seeds. There's some pretty nice fusion going on near the base and some good branching options will hopefully make this something a bit unique in the years to come.
