I am a second-year allotment holder only just getting down to really understanding what I have taken on, and I love this little book. Firstly, it's a journal with blank pages for you to record everything you do, with a page per week. I am hoping it will last at least five years as I only write a few sentences per week, and that will enable me to compare across the years how well/badly I did, what jobs I was doing at what time, etc.
However it also gives a clear summary of "jobs for the month", and it has seasonal recipes from Carol's collection, and it's also really full of useful info (e.g. pages on "chitting potatoes" and "blanching vegetables" ) which will be a shortcut reminder of all the careful advice contained in the big Grow Your Own book.
However DO note that this isn't that book - I think perhaps the first reviewer on here got confused and that's why his wife was disappointed. This is a much smaller book that you could take with you to the allotment to note down where you planted your onions etc, to fold seed packets and planting plans into (it has a useful orange elastic to keep all that stuff in there too - and a wipeable cover, for muddy fingers...).
Honestly if I got this for Christmas I would be soooo pleased, and it's nice and cheap too!
