I enjoyed the book, as it introduces soil types (mineral composition, etc), soil moisture, weed preferences, and how to cultivate, control, or eradicate certain "weeds." Folk, historical, and current uses for certain plants deemed "weeds" were also noted throughout.
Found the book extremely informative, but probably best to use in tandem with a book that is much more visual. I knew a few of these weeds and grew up around them. Knowing what others were, where they grow, etc. would have made this book more enriching. Being inexperienced in the correlations, I found it helpful to myself as a starting, semi-informed amateur to the subject.
It felt at times as though this book was sometimes jumbled and even conflicting with a sub-message of "war on weeds,", but this may have served as a practical hook in the 1950's (original publication period) to keep readers invested.
