This is perhaps the most useful gardening book I own. It allows you to plan your vegetable gardening from week to week, working backward and forwards from the average last spring frost specific for your location. You will be able to tell at a glance when to start seeds indoors, when to transplant them and when to direct sow seeds. There are many interesting tidbits of information and practical suggestions throughout. These sections are very readable, supplying the basic information needed for success without becoming bogged down in a lot of technical background; references and resources given at the end of the book can be consulted if more in-depth reading is desired. I found this book so useful that I bought copies as Christmas gifts for to daughter and daughter in law.
