Ho hum. I bought this book to zero in on early and late planting dates for each vegetable. It did not provide that information. For example, I surmise that I can plant 45 day tomatoes on Aug 20 to harvest before the last frost on Oct 5, but somehow I doubt they will grow much in cool September so I found little value in this book since it shed no light on such scenarios. Worst yet, one main planting chart calendar refers to all the planting dates by Zone. This was useless because I could not find where the zones where defined. The calendar chart refers the reader to a zone map in the back of the book but the map fails to identify the zone's with any notation. Instead, this map identifies temperature zones, but there is no legend to associate the temperature zone with the notation used in the book, i.e. zone 4,5,6. This was a major omission for everyone who wants to know when to plant! Therefore this book is only useful for general gardening information that can be gotten anywhere else. I do not recommend this book for midwest planting calendars. Other than that, it seems to cover general gardening topics and that is why I rated it two stars instead of one.
