So in light of me planting the last tree too deep I have checked my others for the root flare . This Crimson queen is 12 years old . It was buried in an area with a lot of stones . It has thrived in my opinion . I have uncovered the trunk down 9" of rock and clay . Actually top 2" are mulch . It does not look rotted or girdled and I have not hit the root flare yet . Should I leave well enough alone and refill hole or should I find the flare and dig out a good portion around it . Raising it would be quite the chore as the stones go down 2 plus feet in clay . This forum has been so informative and helpful for me in the past. It has fueled this addiction . Oh yes , this is a high graft It is a foot and a half above the soil line . Injoy Memorial Day .
