I'd never before encountered the phrase "vertical gardening."  It refers to gardening with very limited space, such as in an urban setting.  It's all about making plants grow upwards.  Gardening is not farming:  its focus is primarily an aesthetics and secondarily on food production.  If that is an interest of yours, I can recommend this book for beginners.
