I noticed that some of the reviews said that many of the crops mentioned in the book were not suitable for UK conditions, and wanted to correct that assumption.
The book covers ducks, potatoes, corn, squash, and beans, all of which an be grown in this country. The author gives detailed information about all of these, and that information includes the length of growing season needed for those that are frost tender.
The book contains masses of information, and it's principle strength is that it covers the five crops in great detail, rather than lots of crops in outline. The information inludes growing, harvesting, storage, seed saving, breeding, an cooking.
If you are conerned about providing your own food, then this is worth reading. I refer to my copy regularly.
