We concur with this conclusion. Martijn is not only a plant wizard, but also knows all about the successful propagation of planting material and how important it is for food forest owners to at least understand that. He is also a gifted teacher. Martijn teaches the basic module of the annual training and is the instructor in the propagation course.
