Blue Spruce Roots Near Retaining Wall and Foundation

Blue spruce roots won't damage a 6-ft retaining wall or a house foundation 5 ft away. Roots spread ~15 ft at maturity, mostly in top 2 ft with a deep taproot. Slow growth means decades to maturity. Real issue: branches rubbing structures. Prune branches, not roots. Tree stays small with pruning.

Root vs. Structure
