“Dr. Gary Chastagner, officially a plant pathologist with the Washington State University Puyallup Research and Extension Center, is better known as ‘Mr. Christmas Tree.’ For more than 30 years, his pursuit of new knowledge about the trees has been so thorough that it would be called obsessive, were it not science. He has studied tree diseases, analyzed species from around the world, deconstructed tree stands and grappled with that bane of the Christmas tree consumer, needles on the carpet.” Read the rest of the article by Eric Sorensen at
