The PCA’s Invasive Weed Control Group offers advice to homeowners and sets best practice standards for surveyors, construction professionals, and landscapers. The PCA recommends three key actions to help gardeners reduce the risk of spreading invasive plants. First, gardeners are encouraged to speak with staff at their local nursery or garden centre about their labelling systems and any steps they take to highlight invasive species. Second, the PCA advises gardeners to be vigilant and seek expert help if they spot invasive plants. Even small fragments, seeds, or rhizomes left in soil can allow invasive species to re-establish.
