Arborvitae trees near a septic leach field
Hi everyone I am new here. I am trying to find some information on arborvitae trees root systems and if they could present a problem if planted near a leach field. We would like to plant 20 or so of the 10-15ft tall emerald green arborvitaes at the very end of our leach field. They would probably be within 3 or 4 feet of the last drainage pipe. We cant plant them any farther away because our leach field extends almost to the road in front of our house, and the road is what we want to screen with the arborvitaes.
I've been searching the web and this forum for a while and can't seem to find any info on these trees in regards to planting them near a leach field. Does anyone have any experience/info with this?
