Ficus Tree Roots Near Structures: Myths vs. Reality

Don't Remove Those Ficus Trees Yet

Your arborist is correct: ficus roots are not inherently destructive. Root spread is roughly 1.5× the canopy width. Regular canopy pruning naturally limits root expansion.

Root Control Strategies

• Canopy management: Annual pruning to maintain desired size reduces root growth proportionally.
• Root barriers: If a specific structure (pool, foundation) is at risk, install a deep (30–36 in.) HDPE barrier vertically along the hardscape.
• Water management: Avoid excessive irrigation near structures; roots follow moisture.

Choose the Right Pro

Your tree trimmer's advice to remove all trees suggests a knowledge gap. Ask your arborist to recommend a qualified pruner who understands tree biology.
