One to Grow On

Understanding how food production impacts ourselves and our world


One to Grow On is a podcast where we dig into questions about agriculture and try to understand how food production impacts us and our world. Each episode, hosts Hallie and Chris pick an area of agriculture or food production to discuss. Listen for plant facts, dad jokes, and the stories behind your food.

One to Grow On is an older kid-friendly podcast that is safe and appropriate for listeners of all ages. There are a few clearly marked episodes that contain content that may not be suitable for all ages.

Our Story

Catherine and Hallie, March of 2009

Throughout her years in the industry, friends, family, and virtual strangers alike repeatedly asked Hallie the same few questions about agriculture. She recognized that there wasn’t a lot of basic agricultural and plant science education available to the general public.

So she called Catherine, her long-time best friend, and couldn’t stop talking about the idea. Catherine was immediately on-board and they began scheming.

After months of planning and research, Hallie and Catherine had decided to create a podcast, and the next step was finding a co-host. They were nervous that they wouldn’t find someone else who was as interested in the topic and excited to learn about it, but after Hallie got into a long conversation with her dad about the “organic” and “natural” labels, it was obvious he was the perfect choice.

Chris signed on and production began. After two years of working with Hallie and Chris on One to Grow On, Catherine had to step away from her role as producer on the show to pursue her dreams of global policy work.

Now, One to Grow On is a two-person operation with the goal of open and honest learning out loud.
