James, this book was written, as Dr O'Rourke put it, by two old "crotchety horticulture professors". He says "they didn't retire from horticulture but from the clutches of administrators who had kept them from doing fun things". After retirement they were allowed to keep there offices and access to the fields plots for small scale research. This book is from that time period where they did what they wanted and what they enjoyed.
The book covers a little about figs but most of the book is devoted, as the title says, to gardening in the humid South. If you've never been in the deep South during the Summer perhaps you've been in a greenhouse during times when the temps are in the nineties and the humidity isn't far behind. It so hot and humid that you work up a sweat just standing in the shade and thinking about how hot it is. This atmosphere brings on many advantages but along with the advantages comes all the disadvantages. In the book they cover everything from garden tools, and soils, to fertilizers and insects. It's a great book on general gardening principles and practices. If you're looking for a fig book this is not the one although it is entertaining and packed with very good info.
I enjoyed it very much but that might be because I live in the "humid South" and I enjoy gardening year round. I have as much space devoted to veggies as I do trees.
I hope this helps,
