1012: Grow Little for Big Impact: Rachel Opio of Little Lighthouse Farm

On this replay of the Rosie on the House radio show Host Rome and Farmer Greg welcome Rachel Opio, founder of Little Lighthouse Farm, a certified organic urban farm in central Phoenix, Arizona, to explore how growing food in small spaces can strengthen communities and reconnect people with the land. Inspired by her late mother, Lane Bales, Rachel transformed a family garden into a productive quarter-acre farm focused on soil health, biodiversity, fresh local food, and community education. She shares practical approaches to regenerative agriculture, companion planting, seed saving, and growing food in the Sonoran Desert. Rachel also explains how small urban farms can improve access to fresh produce, preserve growing knowledge, and contribute to a stronger local food system. Her advice for beginners is simple: start with one plant, grow something you love to eat, and let your garden grow from there.
