Hi Marla, the shotgun and scatter approach will probably yield the best results. I wish I had remembered to try that, but I was hoping for germination/growth parity with my RS/scion (non dwarf this time) seedlings. I really should start another batch of scion pairs, but it's so hard to discard all those healthy seedlings and I don't have room to nurture them for another round. No one said this would be easy.
