Episode 75: The Science of Soil with Dr Mark from Metrolina Greenhouse - Bloom & Grow Radio

Episode 75: The Science of Soil with Dr Mark from Metrolina Greenhouse

 

 

So excited about this highly request episode on the science of soil. Finding a “soil expert” was kind of tough, but when I met Dr Mark Yelanich on a recent visit to Metrolina Greenhouse, I knew I had found the answers to my prayers. Dr. Mark has been the Director of Research at Metrolina Greenhouses for the past 14 years. Metrolina Greenhouse is the single-site heated greenhouse in the United States at 162 acres under roof. The Metrolina Research department focuses on working with plant breeding companies to find varieties that will delight home gardeners and help them be more successful. The research department also works on finding improved ways of producing our plants to make Metrolina more sustainable and efficient. Before Metrolina Dr. Mark worked for Scotts Miracle Gro (SMG) where he was the Senior Scientist in charge of research on Miracle Gro branded potting and garden soil (and received three patents on soil products). Dr.Mark received his Ph.D., Masters and bachelors from Michigan State University (The Harvard of Horticulture). He is married to Lisa for 26 years and has two daughters Hannah and Emily (sadly neither are going into Horticulture but he is still very proud!)

Today he joins me to break down the different components of soil, and why choosing the right soil is so important for the success of our houseplants!
