Editing a page is very simple. Just click on the "Edit" tab on top of virtually every page, type what you need to, and click save! If there are formatting issues, don't worry too much about those, someone else can fix the formatting issues, and you'll quickly pickup what you need to when it comes to that yourself. For a quick intro see [[Help:Editing]] Some of the text is rather scientific and heavy, that's because of the source it came from. Here we are striving for a more readable and accessible text, so don't be intimidated at all to write in your own style, and to jump in and help rewrite the heavier text to simplify it and narrow it down to a gardeners needs.
