I added a new link to my Stuff I Love page of resources for gardeners: Good Gardening Videos. The site host a well-curated archive of science-based gardening advice.
I particularly admire the videos by OneYardRevolution because the author generously shares his journey, demonstrating how we can learn from mistakes to improve our practice. The 3-part video series below is titled "Popular Gardening Tips You Can Probably Ignore." It's all about debunking popular misconceptions that are not supported by evidence and it's presented in a way that's both light-hearted and informative.
