If you know Cobbett, you know he's robust, idiosyncratic and often at variance with today's ideas. This 170-year-old work is no exception. Don't water your plants? Don't bother to rotate crops? His opinions are thought-provoking and always supported with sensible arguments, though you might think twice before applying them wholeheartedly.
The best section is the first one, of general comments: Cobbett's strength. But most of the book is made up of plant-by-plant accounts of vegetables, fruit and flowers. Inevitably these are not a scintillating read, and they would be more useful if supported by illustrations. But from a practical perspective, they are worth having as an alternative to the conventional wisdom.
I don't feel the book needs notes to make it 'accessible', and nor does the editor provide many: he does little more than flag up the points at which Cobbett's ways are at greatest variance with modern practice.
