    A Garden Chat with Don Titmus

    In this garden chat, Greg and Don Titmus dive into permaculture's eighth principle, 'Information and Imagination Intensive,' highlighting its emphasis on multi-disciplinary approaches to problem-solving using both low and high-tech solutions. They delve into the importance of utilizing quality thought and data to maximize yields and share personal experiences about integrating various systems like passive solar heating, water filtration, and composting. The discussion also covers the concept of food forests, zone planning, and sustainable design strategies for reducing energy and resource consumption. They encourage community collaboration and innovation, reflecting on their own permaculture journeys and offering insights on creating self-sustaining environments. Upcoming events like the Phoenix Permaculture Design Course and the Great American Seed Up are also mentioned.

    Our Guest: Don grew up in London and at age 16 spent 4 years being trained in horticulture through an apprenticeship and a college course. From there he continued landscaping in his hometown until he moved to Arizona in 1981, where he worked in landscaping and then starting his own business in garden maintenance. In 2003 he attended a Permaculture Design Course, which was life-changing for Don. He knew right away that this was the path he’d been waiting for, and later attended two Permaculture Teacher Trainings.
