I set up a garden without chemical treatments at all. This book simply explains the plant associations as the name suggests but there is a whole chapter concerning the fight against harmful bio and a brief explanation on safeguarding harvests. I bought many books on the subject, this one is the one that follows me in the garden. It is very well thought out, even its coverage is plasticized. Just a little flat on the quantity of potato harvest which seems low with this method. Gardeners fit all way. Read and reread to integrate all the data!
