This was my first time collecting one. They are a great species of trees. There was not much of a root ball to speak of. There were some pretty thick roots, maybe 5 or 6, with just a few fine roots hanging on. The soil pretty much fell right off at collection. This is why I was apprehensive about reducing those thick roots. They were pretty long hence the big box.
In hindsight I probably should have reduced them. Would you still consider reducing those thick roots further next spring? Tree seems to be doing really well do far.
