Dappled Willow Shrub Roots and Sewer Pipes

Homeowner asks if a Dappled Nishiki willow shrub's roots threaten sewer/water pipes like tree willows do.

Low Risk

This shrub stays small, so root spread is limited. Only a concern if planted directly over old, leaking clay sewer lines. Modern sealed water pipes are impervious to roots.

No special precautions needed beyond normal planting distance from known pipe locations.
