Weeding and mulching septic system mound
Recently bought a home with a big septic system mound covered with grass and loads of weeds. It is full sun. We put in a few ornamental grasses and lavenders which look great but we need to do something about the weeding and constant mowing we need to do around each plant. Our plan is section 1/to get rid of grass and put in some low sedums or heathers (but harder to grow in this area?) as a ground cover. And back section 2/replace with a flower meadow. Apparently we cannot till or mulch due to damage risks and the importance of maintaining aeration. At this point I think we could A/just use a Weed B Gone product and cover up grass with thin layer topsoil and plant our new succulents or flower meadow accordingly. B/Use an organic biodegradable/breathable paper layer, water, cover top soil and plant. I have read every University extension paper on these septic systems and know what plants to put but am going crazy with lack of what we CAN do. Any tips on what worked for you?
