Plant hardiness zone map update:
Description
In this episode of the Landscape Ontario Podcast, I’m delighted to welcome scientists Dan McKenney and John Pedlar from Natural Resources Canada, who will be discussing the latest revision to Canada's plant hardiness zone map and website, which was last updated in 2014. We'll be delving into the seven climate variables that define these zones, how they differ from the USDA zones, and the potential impact of climate change on invasive species. Additionally, you'll learn about the contributions of citizen science and collaborations with U.S. agencies. Join us to explore the history of these maps, important considerations for growers and gardeners, and the challenges presented by regional climate change. It promises to be a very informative discussion.
