The answer to drainage system invasive plants is that invasive plants can often grow into and clog drainage systems, causing water to back up and create flooding issues. Common culprits include bamboo, Japanese knotweed, and certain grasses and vines that can spread quickly and break through pipes or clog drains.
The symptoms of an invasive plant problem in a drainage system include standing water, slow drainage, and visible plant growth around drains or grates. To solve this, you'll need to identify and remove the invasive plants, then address any damage to the drainage pipes or infrastructure. In some cases, a professional landscaper or plumber may be required to fully clear and repair the system.
