I've had this book for a few years and just re-read it - the fact that I'd not looked at it again since first shelving it, tells you part of the story. It is thick, and lavishly illustrated with both diagrams and photographs as all DK books characteristically are. The first time you look at it, you'll be impressed, and the second time. But if you actually read the text all the way through, you'll be left disappointed. The point about all that illustration, is that there's actually very little text, so you get as much depth (pun unintentional) as you'd get in some smaller books. The stuff on pumps and filters is all very much out of date now, as are some of the garden design fashions illustrated. And there are a few weird bits - how to make a pond edged with railway sleepers... which involves covering the sleepers up with boards ??? Nice to look at, and possibly contains stuff that beginners will appreciate, but for anyone who's already made a pond or two, it will feel rather more like a children's picture book than a serious reference source.
