One safe rule for gardeners

Once upon a time, I lost my footing near an old gardening book, fell in, and ever since then I have been making my way from one book to another, finding all kinds of nuggets of gardening wit and wisdom.

I am fascinated by the connections, the bridges between all these old gardening books.  One author mentions another, my ears perk up and I'm off in search of another writer, another book.
