This thing will probably have a pretty decent tap root on it. I would start maybe 12 inches away and see if you hit any lateral roots, then trench down about the same and dug under it to cut the taproot.
Awesome! I too am entering collected pines for the 5 year native challenge. I usually dig a foot out radially once I locate the direction of the roots (or if a nebari is present). Then I use all pumice substrate once I repot it in a grow box.This will be my first attempt at collecting a pine.
Suggestions on how far out from the trunk I should start digging?
It's in pretty average soil; not sandy. Trunk is 2-3" thick.

Thanks guys.Sweet, I missed this thread. I'm growing a bunch from seed.
As for the tap root, judging from the soil it's going to be a big and deep one. I can recommend digging down in stages, you might not find roots in the first foot of depth, and all of them just below. So instead of digging in a typical V shape underneath the tree, I'd dig a trench straight down and work your way inwards from there to find the biggest root mass. Rigida sparked my interes because of their backbudding capabilities, so a super long taproot would just be a trunk to work with; not that much of an issue compared to any other pine.
