Salix Willow Near House: Root Risk Assessment

Foundation Safety

Fibrous willow roots do not damage foundations. At 13 feet from the house, a 3-year-old tree poses no structural threat.

Roots seek water and will infiltrate leaking septic lines (not sealed sewer pipes).
Mature spread 15–20 feet → root zone 20–30 feet.

If no septic lines run under the tree, it’s safe to keep.
