I just received the "2011 MOON PLANTING guide for gardeners" and I am really impress.
This guide has a colorful calendar with every day of the month with drawings that help you to understand what and when to plant. Also moon signs and other stuff.
It is really easy to understand.
I bought it on Amazon.

I think this guide is much more advanced than the Farmer's Almanac and takes in consideration the Zodiac signs.
