Planting depth looks pretty good. I would have split the difference between the existing soil line on the trunk and the level you have it planted. Once you add a couple inches of mulch, all the roots will be covered anyways. Planting hole itself looks a little too narrow but that is hard to get a feel for. I suppose you could have spread the roots out a little instead of leaving them straight down.

I agree it is grafted and likely 'Wildfire' or 'Firemaster' as they sell both with the former being most likely since 'Firemaster" is out of stock. I paid a little extra for a 'Wildfire' and ended up with a species. Just getting these picky trees going is an accomplishment and worthy of a permanent spot. Good luck with yours. Make sure to give it plenty of water this summer!

Looks just about right, Richard. Though there is little in the way of a "flare" to that rootflare, it is the point of divergence between trunk and roots, so you're golden. Like John said, now just bring some mulch to it and cover those roots a bit.

yep-er-ree ...

maybe a half inch high ... but frankly.. who cares ...

perfect

to me.. you have rough bark.. that transition right where the roots part ... to a smooth root covering.. top part = bark .. lower part.. root covering ...

do not confuse what looks like a graft 3 inches up or so ... where it suddenly thins .. is that a graft?? .. what is that type of grafting called ...
