Q: I want to plant pecan trees in a low lying area that floods every eight to ten years. The water can get as deep as one meter and stays there for two to four weeks. Can a pecan tree survive in such high water for so long?

A: Pecan trees are somewhat flood tolerant, but the trees’ resistance to the water depends on when and how long the water stands.

For more information, see the University of Tennessee’s page on the Shade and Flood Tolerance of Trees (PDF).
