Root pruning at planting help needed
Today I planted a Legacy sugar maple. There were several roots at the top of the potting soil coming directly off the trunk but they seemed comparatively small. I washed most of the potting soil off to bareroot as much of the root mass as possible and found the original flare several inches below the secondary roots that must have come about from being buried too deep in the pot. I proceeded to plant the original root flare just below ground level leaving the secondary roots way up in the air. I then pulled them out and covered as much as I could with dirt and the rest with mulch to prevent drying.
My first instinct is to prune them but this is probably at least 1/2 - 3/4 of the root system including feeder roots. Should I leave them for a year or two or clip them now?
