Are Girdling Roots Dangerous for Trees?

As roots circle the trunk, they can slow, and eventually cut off the flow of sap in the tree. Carbohydrates produced by the leaves, through photosynthesis, are unable to move through the phloem to the roots. They may form in root-bound container grown plants, begin when a tree is transplanted, or develop as a tree grows. Poor planting techniques, deep mulch, or compacted soil seem to encourage the development of girdling roots at the base of the trunk. Trees with girdling roots tend to decline over a 5-10 year period. Trees and shrubs that are container-grown and pot-bound frequently develop girdling roots.
