Wow! That last URL (http://extension.usu.edu/files/publications/publication/FL-HI-500.pdf is great.

I have learned a lot from all of you. Thanks a lot!!

It is this back and forth that helps so much more than a Google search could ever do. Articles like this one are great but there are so many times that, when you find an answer to a question, it spawns two more. And nothing in the world (or on the Internet) can replace the wisdom and experience of people who have been doing the things you are trying to learn. Books are good but teachers are better.
