Polyculture design can be bewildering and even intimidating. I’ve been planting and thinking about polycultures for over two decades. During that time I’ve planted a lot of failed polycultures that didn’t work for one reason or another, as well as some successful ones. I’ve also visited many sites in many climates and seen polycultures functioning very well – especially in the tropics, where agroforestry systems are much farther along than my cold temperate home. I’ve assembled a set of guidelines for designing polycultures, that I’d like to share with you. They are a work in progress and far from perfect, but, in concert with the design process shown below, they have helped hundreds of people in my courses and workshops to feel ready to go home and design and install their own polycultures.
