Invasive Species Focus - Upcoming Webinar September 25

The Toronto Master Gardeners invite you to attend this free webinar sponsored by the Invasive Species Centre. Ornamental horticulture is the main source of invasive plants. Many invasive plants that pose a particular threat continue to be readily available in garden centres. This presentation will explain what it means to say that a plant is invasive, the impact of invasive plants on the natural environment, identification of some commonly available invasive plants and alternative plants to consider that will have similar landscaping effect while enhancing the ecosystem. The content will also cover management and safe disposal of existing invasive species.
