1.5/5⭐ Almost everything in this book is so surface level as to be utterly useless, if not downright lacking vital important information (e.g. for herb use) or providing misinformation (e.g. re: smudging, citing flawed studies).
The summary emphasizes all garden space sizes, but the text focuses solely on large yards.
There are much better, more reliably informed books out there on all these topics. Give this one a pass.
