998: Water Harvesting Beyond the Basics with Don Titmus

A Rosie On The House Replay

In this episode we explore the concept of wicking bed gardens, hosted by Romey Romero & Farmer Greg, our guest is Don Titmus where we find that Water harvesting is about far more than capturing rain, it is a foundation for resilient landscapes, healthier soils, and regenerative living. Greg Peterson welcomes longtime permaculture educator Don Titmus to share the evolution of his Mesa, Arizona property, beeOasis, and the lessons he's learned from decades of designing landscapes that work with nature instead of against it. Together they explore permaculture principles, rainwater harvesting, biodiversity, and how small design choices can create thriving ecosystems in urban environments.

QuestionsHow did beeOasis get its name?

Don explains that after attending a top-bar beekeeping class, he realized his property naturally provided everything bees need—water, flowers, trees, pollen, nectar, and shelter—making it a true oasis for pollinators.

Why did Don stop keeping bees?

Although his landscape was ideal for bees, the hive's location near his compost system made routine compost maintenance difficult because the bees aggressively defended their territory. He ultimately donated the hives while continuing to maintain the property as pollinator habitat.

How did Greg and Don first connect?

The two met shortly after Don completed his first Permaculture Design Course in the early 2000s during an event at Greg's Urban Farm. Their shared passion for regenerative design led to years of collaboration through the Phoenix Permaculture Guild.

What role did the Phoenix Permaculture Guild play?

The guild became a hub for education, demonstrations, public tours, and community outreach, helping spread knowledge about rainwater harvesting, graywater systems, and sustainable landscape design.

Why is naming a property important?
