James Gregory, a seedsman from the early 1800, describes and details his methods and experiences of growing onions commercially. The information contained in the book is just as relevant today to gardeners with vegetable plots and allotments, as it was to the commercial growers of the time. His advice on soil types, manure, sowing and planting, hoeing and weeding will help any vegetable grower achieve good crops without the use of modern chemical applications.
