Answer: Two excellent resources come immediately to mind; National Gardening Magazine, published by National Gardening Association, 160 Flynn Ave., Burlington, VT 05401, features a regional list of things "To Do in the Garden" in every issue. Typical gardening chores, suggestions for planting and pruning, and tips to help you plan ahead are included for all gardening regions in the U.S.
The second resource is the book Gardening Through the Year, by Hazel Evans. This book is divided into 12 chapters, one for each month of the year. It outlines major tasks, details techniques, and reminds gardeners of necessary chores. While it's not specific to California, it will certainly help you plan and maintain your garden.
