I like this book. It is not a serious self-sufficiency guide, nor a serious gardening book, but it doesn't claim to be either of those. This is one person's experience and advice re. growing food on an allotment, together with some recipes and some anecdotes. It's a book to dip into every couple of weeks to see what you might want to do at that time of year, in terms of sowing, harvesting and cooking. I haven't read it cover to cover yet, I am doing the regular dip into it, so will probably take the whole year to get through it, which is my practice with other more serious and more detailed gardening books that are divided into months or seasons. However, I have found New Urban Farmer easy to read and useful, despite its beginner level feel. I wouldn't say I have learned a lot from it (I have read many other gardening books and have been growing vegetables on and off for years), but have learned some bits - that you can eat the leaves of courgettes and cucumbers was news to me, but something I will try this summer.
As other reviewers have said, it has the feel of a coffee table book rather than something you keep in the shed or greenhouse, but despite that I do keep it in my practical book corner rather than anywhere near the proverbial coffee table. If you are serious about gardening this will definitely not be your only guide to the gardening year, it's not detailed enough for that, but it does have a fresh feel to it, which reflects the author's previous writing experience.
