Pretty good basic information for new gardeners who want to use organic methods to grow the usual American crops. I consider myself a seasoned gardener and a geek, and didn't find this particularly geeky or helpful in terms of new material, but there were some very cool elements to it. I didn't feel that it gives all you need to be successful. There were a lot of plants profiled where the instructions for growing and troubleshooting didn't include anything about my common problems with them (for instance, carrots get temperamental if the soil isn't very loose and I always have problems with my potatoes even though they're supposed to be so easy and I do hilling and all that jazz). I also grow a ton of stuff that's not covered, so do consider it a very basic intro in terms of crops. It goes into a few things like square foot gardening and some French gardening techniques, but not a lot into permaculture.
It's geeky I suppose in terms of providing detailed information, but I thought it would be geeky in terms of fun science kind of stuff (for that kind of garden geekery, I highly recommend the new book Garden Alchemy). All in all though, a great, thorough guide.
One more small complaint is that it could use photos for specific instructions. There are a lot of color photos but it's the classic book where they sometimes use stock photos so when you actually need photos of all the kinds of ways to make trellises, for instance, there aren't any. I'm always frustrated with books that use stock photos for this reason, because sometimes things just don't come through well in text and a random picture of one kind of something doesn't really help (this is similar to the new cookbook trend of filling a book with artistic color stock photos of raw vegetables instead of the finished actual recipes). There are times in the book where the author uses relevant pictures for some plans, but I wish other areas had more pertinent photos. That said, there are a lot of color photos and they add to the book.
I read a temporary digital ARC of this book for the purpose of review.
