Title: Texas mountain laurel roots and septic systems
Answered by: Joe Marcus
First, you should know that we cannot recommend Sophora secundiflora (Texas mountain-laurel) for you project since it is not native to your area. Instead we hope that you will find a suitable plant that is indiginous to the Yuma, Arizona area. However, we doubt that the roots of Texas mountain-laurel would be a problem for your RV Resort's septic system. This species grows in very dry areas and does not perform well in compacted or wet soils. The roots of this species should not find their way into septic or drainfield pipes.
