Oleander Roots and Pool Foundations: Assessing the Risk

Root Spread Rule of Thumb

Root spread roughly equals canopy spread. If the oleander's canopy extends 3 feet from the trunk, roots likely reach that far. Most oleanders grow 6 feet wide (3-foot radius); some varieties reach 20 feet.

Action Steps

1. Identify your variety (check label or consult nursery).
2. Measure canopy radius.
3. If canopy edge is ≥3 feet from pool, risk is low.
4. If closer, consider root barrier installation or relocation.

Note

Oleander roots are not typically aggressive foundation destroyers, but proximity to a pool warrants caution.
