This is the book that guides all of my magickal gardening work! Lots of interesting almanac-style gardening articles, and the most reliable astrological moon sign information, based on NASA data. If you want to learn how to use this ancient agricultural system, this is the best book. I totally LIVE by mine and get it every year without fail! The nitty-gritty information, the Moon Sign Tables, begins on page 136.
Additionally, the exact times of the Full Moon and New Moon guide all my spell workings and potion makings. This is THE book every practitioner of Moon Magick needs.
Also critical info on the exact timing of Moon void-of-course and retrogrades of all the planets is a page that I keep bookmarked year-round in this book.
