Do aspen trees spread were they will interrupt my septic system as well as other peoples in our area. I was told they can grow into a grove. How do they spread?
Yavapai County Arizona trees and shrubs
Aspen trees spread by underground roots and suckers grow from these roots to forma a stand of trees where conditions are favorable. Aspens prefer cool moist sites and often do not thrive in Prescott area landscapes where water is often a limiting factor. They can invade leach fields and cause issues with septic systems too. They will not "seek out" water or nutrients, but if they encounter them, the roots will proliferate.
