We are building our dream home that requires installation of a septic system. The size of the block is just over an acre. We have a couple of spots on the bare block that I would like to plant something substantial that will be lush, green but more importantly, create privacy. I have some ficus topiary trees that have been in pots for over 15 years. Would these be detrimental to the septic system?



Hi Stacy,  Most evergreen figs have nasty root systems that block drains and break concrete. Plants won’t grow well on rock.
