This week, garden myth-busting expert, Robert Pavlis joined me to talk about gardening products. Robert has a background in chemistry and biochemistry and is an avid gardener as well. He owns and runs a 6-acre botanical garden packed with over 3,000 different species of plants, trees and shrubs. So, he offers some valuable insights when it comes to determining whether or not a product is necessary - or even beneficial - in the garden.
