The Be Plant Wise campaign, launched by Defra and the Scottish Government, is designed to raise awareness among gardeners, pond owners and retailers of the damage caused by invasive aquatic plants and to encourage the public to dispose of these plants correctly. We have developed resources with advice for gardeners and pond owners and are working closely with retailers of aquatic plants to provide information in stores. These pages contain the detailed information you need to Be Plant Wise.
