I found that it wasn't necessary to actually hassle with bare-rooting the seedlings.
The stems were long enough on all but two so I could just snip them at the soil line and then fine tune the cut with the razor to the exact measurement dictated by the match stick.
Dip in hormone and then use the other match stick to create the proper depth hole and insert the cutting.
Then I used a tool not shown above to compact the moss/perlite medium up against the sides of the hormone covered stem.
Cut them all, a good dose of fresh water and mist, then on with a hood and onto the heating pad.
The heating pad is keeping the interior of the tray between 72°F and 75°F.
And that's it.
Here's the finished group of 8 (the empty 4 slots are for some other cuttings not associated with the JBP contest).
5. = Pinus aristata
15. = Pinus sylvestris
19. = Pinus Thungergii
21. = Pinus virginiana
So, I'm not sure, but I think these may be the first actual seedling/cuttings officially presented for this contest (not that it matters).
