I have used both workbooks I and II, and have been amazed at the transformation my garden (and I) experienced. As a novice, I didn't fully understand the information "nature" was sharing with me and went on blind faith. Three years later, as a horticultural student, I have the scientific "aha" of understanding the amendments, plant choices, and design I was given. I admit--this is way out there, and yet it makes so much sense. There is no area--no space--that the principles taught here cannot be applied. Gardenig and Life can be easy, and Machaelle shows you just HOW easy it can be!!
