Reviewer: Jackie Patti from Carlisle, PA United States   - 

I love this book. I have read hundreds of gardening books, mostly taken out from the library, but have only actually shelled out the cash to buy about 5. This is the only one I recommend to people regularly.

I went to the author's website and emailed him a couple questions. The guy emailed me back with replies in less than a day. That was really nice of him.

BTW, one of his replies was that the recommended spacing for potatoes is one to a square if growing to full size, or 4 to a square if growing for new potatoes (or a small variety).

He said he would post to his site with more info on my second question. He has a lot of other additional info available on his site as well.

The site is great for owners of the book. But get the book, it fully explains the system and includes reference tables for many types of plants. It's indispensable.
