175-Decoding Gardening Advice, With Dr. Jeff Gillman – Encore Presentation

| Care, Podcast

Despite the best efforts of gardening educators to debunk poor gardening advice, bad information continues to be shared online and elsewhere by well-meaning, though ill-informed, gardeners. To keep up the fight against bad gardening tips that persist, this week I am sharing once again my conversation about decoding gardening advice, with Dr. Jeff Gillman, a horticultural scientist who puts common gardening recommendations to the test to determine what’s really backed up by science and what advice is a waste of time — or even detrimental.

Jeff is the director of the University of North Carolina Charlotte Botanical Gardens and is a former associate professor in the department of horticultural science at the University of Minnesota. He holds advanced degrees in both entomology (the study of insects) and horticulture and is the author of five books on gardening and the environment, including the book that inspired this episode, Decoding Gardening Advice: The Science Behind the 100 Most Common Recommendations.”

From the use of landscape fabric, fertilizer and mycorrhizae, to tree topping and best practices for seed starting, watering and pest control, in our discussion, Jeff exposes which gardening advice is debatable, at best, and just plain wrong, at worst.
