Will schefflera tree roots harm a septic drain field?

Schefflera tree roots are generally not aggressive and are unlikely to harm a septic drain field. However, any tree roots can potentially infiltrate and disrupt septic systems if they grow too close. It's best to plant schefflera trees at a safe distance from the drain field to minimize any risk. Regular maintenance of the septic system can also help prevent any issues related to nearby vegetation.
