Hi Thomas Giannou, Thanks to you, Thomas Giannoe, for those resources of more information on Mycorrhiza. I will start with the one from West Virginia, I think. It looked most interesting to me, as I hurriedly bookmarked each one to study later. (I am not planning on it taking the rest of my life, though.) After doing quite a bit of reading on it, I have ordered some Mycorrhiza root booster from another company, which was mentioned in one of the newsletters last year. I am going to experiment with it on half of my Habanero chile pepper plants, and on some other vegetables. I will also use it on some of the heirloom tomato seeds I purchased from Chuck Wyatt. I am so excited to try heirloom tomatoes this year, thanks to Margaret's letters to the list, Chuck's letters, and others. Since it will be my FIRST experience with HEIRLOOM tomatoes, I will try Mycorrhiza on only a few to compare the results with the other seeds not receiving that treatment. I have absolute trust and confidence in Chuck Wyatt's words concerning gardening, but I am also a very curious individual. I want to learn more (in addition to what I have read so far) about the validity of the claims and research studies made on Mycorrhiza. At the end of the summer, I will report on my "unscientific" experiment, and let you know if I feel very foolish for ever trying it. Marguerite Ruch On the shores of Truman Lake in Missouri
