Make your septic field a thing of beauty with this mix. This mix has been designed using plants that prefer dry soil because the root systems of these draw moisture from the septic system helping to make it more efficient. Takes advantage of subsoil moisture when present, but also able to tolerate dry periods. ReGreen can be added in quick cover and erosion control situations.  Birds and butterflies will be attracted to the flowers that bloom spring to fall. 

Native plants are uniquely qualified to handle septic fields. The range of moisture levels can be challenging for ornamental and introduced species. The deep fibrous root systems allow for great filtration. Native herbaceous plants lack a deep tap root like most shrubs and trees have, It is these tap roots which typically pose a risk to damaging the septic system's underground piping. Native plants help with filtration, provide much needed habitat for wildlife and look amazing. These native plants also create a landscape that keeps you from having to mow. Mowing septic fields can be challenging.

This mix is great for your septic field, but what about the septic tank, inspection ports and manhole covers that are protruding from the ground and have taken over your yard? There is no way around it, they need to be there, but you can try and disguise them. Short growing native plants are typically 3 feet and they only get taller from there. Native wildflowers and grasses are great at hiding these units. Utilizing native plants around these units hides them from site and creates habitat. Try creating a border around yours with ones of these native seed mixes:
