Rubber Tree Roots & Sewer Lines: Invasive Risk Real

Large potted rubber tree (Ficus elastica) moved outside as privacy screen. Water dept says roots will destroy sewer line. Likely?

Yes—Ficus Roots Are Aggressive

Rubber tree is invasive in warm climates. Roots seek moisture → enter sewer cracks → expand → block/break pipes. Any tree near lines risks this; Ficus is notorious.

Options

• Keep in pot (root-prune annually).
• Plant far from lines (>20 ft, with root barrier).
• Choose non-invasive screen (e.g., clumping bamboo, holly, viburnum).

Water dept warning is valid.
