We’ve got significant cold weather headed our way in the next week. Hope this is being kept frost free. Also. I would avoid the impulse to collect another right now. See how this one goes for at least a year. Initial budding IS NOT the best evidence a tree has “made it through”. It can result from stored internal in the trunk not from new root growth
It has been too cold for much of any root growth for the last month
Also liquidambar is notoriously finicky about root reduction timing.
