Prevention is the best treatment for girdling roots.
Plant trees at proper depth
Root bound trees should have roots pruned or if pruning will not correct do not plant
Ensure hole is wide enough (in very compact soils hole should be at least 2 to 3 times the width of the root ball at the soil surface)
If girdling roots occur Wellnitz Tree Care can expose roots with an Air Spade, and properly prune girdling roots away from the tree. If girdling roots are severe enough that they cannot be corrected without causing significant to the tree, the tree’s stability is compromised and should be removed.
