growing nut pines from seed
I currently have one Italian stone pine (pinus pinea) that's been in the ground for about 3-4 years and one Korean nut pine (P. koraiensis) that I ordered as a bareroot tree and potted up in the spring of 2012. My understanding is that I need at least two of each for cross-pollination to ever have any hope of getting nuts. I'd like to have 3-6 of the Korean nut pines anyways. I've actually purchased a total of 4 bare root Korean nut pines already and only had one to establish well and survive. I'm wondering if I'd be better off starting them from seed, and I want to grow some from seed anyway. Is nut pine seed available to purchase anywhere? Anyone on this forum (in the US) have seeds he could sell (or trade, if I happened to have anything he wanted)? Any pointers? Thanks very much!
