How should girdling roots be addressed in transplanting and mature trees?

• A. Ignore girdling roots
• B. Identify and remove girdling roots where possible, adjust soil to expose the root collar, and avoid future girdling through proper root pruning
• C. Only prune above-ground limbs
• D. Avoid transplanting trees with girdling roots

Answer: (B)

Girdling roots restrict the flow of water and nutrients by wrapping around the trunk or major roots, which stressed trees struggle to overcome. When transplanting or caring for mature trees, the aim is to remove or relieve those constrictions and encourage roots to grow outward rather than in a circling pattern. The best approach is to identify girdling or coiled roots and remove them where possible, exposing and restoring the normal root system. Setting the root collar at the proper depth by adjusting the soil helps prevent the collar from being buried or buried too deeply, which can foster new girdling problems. To avoid future girdling, prune roots properly at transplanting to promote outward growth and reduce the chance of roots turning back toward and constricting the trunk. Ignoring girdling roots lets the problem persist and tree health decline. Pruning only above-ground limbs ignores a critical part of the tree’s system, since the root constraints are the main issue for vigor. Avoiding transplanting trees with girdling roots is impractical because you can often correct the problem through root removal and proper planting technique, preserving the tree rather than discarding it.
