Bernard, Charles. My Handkerchief Garden. (New York, E.H. Libby, c1889). Available in paper or cloth through various sources, including Amazon for $15 – $25. Also available (currently free) in a PDF version through this website.
The little book above (64 pages in my edition) was an enjoyable read providing a vision of the doable in gardening for frugality and health with even a city-sized lot. 25 feet by 60 feet is a large handkerchief, but a manageable garden, especially considering the legible drawings are further explained, and considering the author’s recommendations on tools and methods. It would be well worth the purchase price if one prefers a paper copy of the book.
