I am concerned that the roots of these shrubs may be invasive to sewer and storm water pipes and need to know if that is correct.
I would appreciate your expertise.
Hi Cheryl, Any plant can grow into pipes seeking water, however, 99% of the time that this occurs is when the pipes are made of clay and are already leaking at their joints. IE the pipes cause the problem, not the plants. If you have modern plastic piping, there is little to worry about. While Oleanders are not water-seekers, all lillypillies are water lovers. Nonetheless, in the very rare case where they break pipes, it would be entirely by accident – plants are not clairvoyant enough to guess that inside a plastic pipe there is water. The nasty plants that break footpaths, gutters and roads are mostly evergreen figs (Hills weeping fig and other rainforest figs are the worst) . Don
