The book gives good tips on lawn care, but must be one of the most disorganized writings I have ever seen. Information is provided in bits and pieces here and there, and is someitmes inconsistent. For example, the beer & amonia tip is given on at least three occaisions, each time with different mixture ratios and "optimal" application dates. Chapter 11 makes a half-baked effort do give a summary of the most important points in one place, only to be followed by a Q&A chapter the muddles the situation. If you have the patience and desire to sort out the mess I think that the book is well worth the price.
