Landscaping around your Septic System

Love flowers? Like a nice shady spot to cool off under? Me too! Landscaping can add so much character, comfort, and charm to your yard. Just because you have a septic system doesn’t mean you have to miss out on having a beautiful yard! Below is a list of plants approved by landscape artist and septic specialists alike to help you landscape! This list was originally made by landscape designer Wynn Nielson.

As always check to see if the plant listed is appropriate with your soil type (clay vs sandy) and the sun conditions of your yard. Also, do not plant trees directly over lines or the tank. Now onto that list!
