Sitka Spruce Surface Roots Near Foundation: Prune or Remove?

30-ft spruce (likely not Sitka—inland) 10 ft from 15-yr-old house. Surface roots emerging on house side; foundation 4 ft deep.

Foundation Risk: Low

Roots in top 2 ft; footings deeper. Roots turn along foundation or go down. Real issue: branches will rub house (spruce spread 20–30 ft).

Options

1. Prune annually to keep canopy off house (leave green foliage, don’t top).
2. Remove if pruning commitment unwanted.
3. Mulch surface roots (2–3″ chips)—don’t cut or bury.

Root Barrier Alternative

Install trifluralin fabric along foundation to divert roots—but branches remain a problem.

Spruces can be pruned any time (lateral buds). Late winter best.
