Lynda Chalker-Scott, one of the founders of the 'garden professors' who put some sound science in our hobby is under fire. Apparently for doing her job. For those who do not know her, she debunked a lot of garden myths showing where they were right or wrong. Also, she is the author of "The Informed Gardener" and similar books.
