Can You Plant On A Septic Field?
You can plant on a septic field (rather than having it as lawn) but the choice of plants depends on the design. For example, if the pipes are buried just 30-50 cm below the soil with limited pea metal around them, you will want to just stick with grasses and shallow rooted shrubs. If the system is at 1 m and surrounded by large volumes of pea metal or gravel, any shallow rooted species will be fine.
