I've been looking over this book trying to decide if I need to buy one for my own library or just borrow the local library's copy when I need it.
I decided I need one for myself.
I find the book practical and friendly. It'll be on my bookshelf before harvest time next year.
The book is divided into plant families. There are clear instructions for when and how to collect and store seed. There is a great description of how to pollinate squash plants yourself to prevent cross pollination with other types of squash.
