How many years can it take for trees with a caliper of 4-6 inches to regain a sufficient root system after transplanting?

Transplant shock can significantly affect a tree's ability to reestablish its root system after being moved. Trees with a caliper of 4-6 inches are typically well-established, but moving them can disrupt their roots, creating a period where they struggle to adapt to their new environment. It generally takes about two years for these trees to rebuild a sufficiently robust root system capable of supporting growth, especially as they adjust to changes in soil conditions and moisture levels after transplanting.

During this time, the tree may exhibit symptoms such as reduced growth or leaf drop while diverting energy toward rebuilding its roots. This two-year period is crucial for the tree's recovery and long-term health, as a strong root system is essential for nutrient uptake and stability in the landscape. The other answer choices suggest shorter or longer recovery times, which may not accurately reflect the complexities of root system development in transplanted trees of this size.
