[CANUFNET] Frazinus ssp. -do their roots plug drainage systems

[Stephen Smith]

Green ash likes floodplains and wetlands.  It might go after pipes.

  Does anyone have experience with Fraxinus ever having entered and plugged perforated drainage pipe? I assume the deeper the pipe the less chance of it happening. I am only familiar with Salix, and sometimes Thuja plicata, doing this. My feeling is that a tree's roots would not search out drain tiles unless it was suffering drought conditions. The water held in the soil is a much more constant supply with adequate rain.

  My client has a neighbour whose house foundations are 15 feet from the base of a 35 foot high Fraxinus. The foundations are 3 feet below finshed grade. The neighbour worries the trees roots will grow into her perimeter drain pipes. Any comments?
