I just got a new house, and I want to garden. I have a copy of John Jeavon's book, How to Grow more Vegetables, which inspired me and showed me some excellent tips for organic gardening. I think this book has given me enough knowledge to become a decent gardener.
The book (mine is older, from 1982) explains Biodynamic / French Intensive techniques for growing crops. Some of the major components are pre-digging the soil to loosen it and growing crops close together to create a micro-climate. The book also advocates building up soil rather than depleting the nutrients.
I hope to get the new book soon (this one).It is an expanded version of this excellent book. For now, I will use what I learned from the book I already have.
