In this episode I interview Jackson Farmer, also know as, Farmer Freeman. He has been gardening for 16 years and has a Bachelors and Masters in Biology from American University. He grows a variety of plants and owns a company that specializes in plant testing, such as DNA sex testing and testing for pathogens. He talks all about various types of plant pathogens, their symptoms, how to test for them, and how to combat them - if possible.
