Other Comments:
We have been given an elderberry plant, do not know the variety, in small pot at present. If planted in garden is it likely to be a problem and pose a root (invasive) problem too close to septics/leach drains? Your advice please. Thank you, Norm.

Answer:
Hi Norm, Elderberries are thirsty, water-loving plants that will not survive drying out. IE they are not great plants for WA. But they are good plants in WA around septic ooze and runoff areas. Presuming that you have an absorption area for the septic runoff, all should be fine since the plant will love the wetness of it. I doubt that the Elderberry will clog any pipes provided that you don’t plant it closer than 3m from the pipe outlet/s. Don
