For the newer guys, do not take what you read in the paper, hear on TV or radio, or even what you can read from plant books in the library, as actual fact and truth about plant and lawn care. As for the media, when they want a question answered, they call someone in the business in question. So they ring up the local nursery, and who answers the phone there? Right, the new guy, and it's spring and the boss said not to bother anybody except in an emergency, because we're so busy. So the new guy doesn't even know what a yew is, but if it's looking scruffy, water would probably help. And the answer to fixing the drowning yew is to water it 5 times a day. LOL If getting your info from books, who wrote the book? It is human nature to be drawn to plants and nature, because we come from nature. Too many people have dramatic success in their individual garden endeavors, and decide to share their magic bullets with the world, and write a book. Problem was, what they did on their site was great, but is totally wrong for soils 2 miles away. Or the plants in question were a certain cultivar, and their results are attached to the whole species, etc. There are good books to help, but you have to know the sources you can trust. If you really want to learn what is right, go to your county extension program. Some states have hundreds of fact sheets on plant care. You could also ask about training from the extension office. They could direct you to state or local training programs. There are nationally recognized programs run by ALCA, PGMS, and PLCAA, which can be completed basically on your own time. IN has a Master Gardener program, to get you deeper into understanding plants in general. INLA (IN Nursery and Landscape Assn) sponsors IAP (IN Acredited Plantsman) and Master Plantsman programs.
