I bought this book twenty years ago. I read it and didn't do it. Now I am on a farm and have a half acre garden. I re-read the book, and after three years of mulching a la Ruth Stout, and putting in the tomato fence that is described in one of the later chapters, I truly have my garden under control.
It didn't happen over night. It took three gardening seasons for the mulching to become very effective, because each year the weeds are under a little better control. Last summer, I wasn't ashamed of my garden, not even in August, when it used to be a complete tangle of weeds. A nice side effect is that all of that mulch turns into wonderful compost, just lying there in the garden. No turning, no nothing, just mulch and let it do its thing.
Buy it and try it - it will change the way you garden forever!
