@Charlie- I'm very thankful for the horizontal method you directed me to, especially since I spaced the 1,500 cuttings so close together! Imagine what a nightmare it would have been to separate out the trees if they had all come up! Next time I'll just space the cuttings farther apart and probably try a similar method, but possibly with the cuttings vertical.. So you think 20' x 20' orchard spacing is OK? Do you think HC will get frozen to the ground each year and therefore maybe I should space them more like 15' x 15'? Thanks for all the help Charlie.
@Tennessee Fig- I was wondering about rot due to winter covering with leaves, mulch, etc. Thanks for sharing. I am pleased with using row covers, but it really only works well covering nursery rows/trees that aren't more than about 3' tall and maybe the same width.
I spread 1500 cuttings out over 500 linear feet of mounded row, so that means an average of 3 cuttings per foot. They were spaced 6 inches apart in either direction and laid horizontally. The first year I rooted fig cuttings, I used a much more micro-managed method involving cups, domes, etc and I knew I could never handle a large nursery that way. The newly-tweaked method in a nutshell has the cuttings sit outside inside mounds of homemade biochar for a couple months (no rot, no humidity monitoring). Cuttings start forming initials and roots and then the cuttings that seem viable are transferred to about a 1' x 1' spacing in mounded rows and possibly all nodes/buds covered with mulch unless no frost is expected for the rest of the spring. I think it might be good to place the cuttings vertically, just of course be sure to not damage the roots and make sure there is very good drainage.

The varieties I have are: Unk "Apple", Madeline's Yellow Italian, Madeline's Dark, Madeline's Green Greek, Hardy Chicago, Jim Dandy, Alma, Champagne, Celeste, Unk "Mrs Clark," O'Rourke, Hunt, TX EB, LSU Gold, LSU Purple. Then I have six or seven other varieties growing as 2 year old trees, but none of those varieties in the nursery..
