Gardening Vertically, by Noemie Vialard was originally published in France in 2010, but has just recently been translated and is now available for the English speaking North American audience.
This book belongs on your shelf. The author, admittedly Patrick Blanc's close friend and frequent collaborator, begins the book with 40 pages devoted to the French green wall innovator. Detailing his style, methods and background, it reads a bit like an extended Blanc biography/promotional piece. Which is fine, we also get insight and an in depth look into his work and inspiration, complete with tons of pictures and full equipment, hardware and support lists to build your own Blanc style wall. With step-by-step instructions the last 100 pages are filled with other techniques (a few time honoured and others fairly recent) for your own DIY projects, included detailed plant lists for achieving the wall of your dreams.
The possible projects are exhaustively described, including the lifespan of the plants in the wall, maintenance requirements, prep time, planting time, the best locations and harvest times as well.
It's very handy as an all-in-one resource for anyone interested in the green walls, especially the mechanically inclined DIYer.
