Re: Rooting plants from cuttings . . .
Inkcube, it isn't really actually a pine at all. It is Wollemia nobilis, and is in the Araucariaceae (sp?) family. There isn't much information out about how to propagate it because they don't want you to, lol. The leader I would be removing is one of three, and isn't the main leader. You can prune the leader off on these and they will grow a new one. Oh, and yes, I am using it as a stock plant.
I think I just found my answer though. I looked in my Plant Propagation, Principles and Practices, (Hartmann and Kester), and they say to use semi-hardwood cuttings for Araucaria species. I assume it would be the same for Wollemia.
