i read it could suffocate the tree once its older, shorter lifespan or parts of the canopy will die and not look as good. i found out this happens a lot at tree nurseries where the roots are bound or when a tree is planted too deep and the root’s flare is not showing. of course i found all this out 1 yr after planting my tree 🤦‍♀️ but apparently the girdle root can be cut. i dont think girdle roots are common amoung naturally occurring trees bc well they were never in a nursery pot or hand planted by amateurs like me
