Funny that you should ask, dirk. I have spent the last two weeks repotting all my JBP stock. I have been growing from seed for 5 years so I have many trees of various ages. My oldest seedlings were not seedling cuttings, so about half have pretty sub-par nebari. Some I was lucky enough to get nice root development, but the others I knew would be poor material without some serious intervention. I used a couple 2 year old seedlings to approach graft on the 5 yr old pine bases. We will see what happens in a couple months when I check in on the grafts. If they do take, I might just let the grafts run wild as sacrifice branches to build very large bases. This is my first attempt at grafting a pine, but the process seems pretty simple and fool proof. I made a pretty deep notch on the parent plant. The seedling fit in semi snug. I scraped the side of the seedling that was going to fit into the cleft, and I stapled the seedling in place. I then covered the whole thing in wound sealant to keep the graft moist. I am hoping for the best, and I will keep you posted!
