PULLMAN, WA – The newest episode of the Ask Dr. Universe podcast digs into the dirt with Washington State University Extension vegetable specialist Tim Waters. Listeners learn what Extension is, how it links WSU with communities across Washington, and why Waters’ job sometimes means racing into fields to solve plant problems before they spread.

Waters shares how his role has changed since 1918, when the first Extension agent in his county spent much of the job helping families clear sagebrush and keep jackrabbits out of their crops. Today he works with farmers, gardeners, and curious neighbors to diagnose insect mysteries, track down fast-moving plant diseases, and even identify scorch patterns caused by lightning.

“I really like helping people,” Waters said. “When growers call me with a problem, solving it can make a huge difference for their farms and their communities.” He also talks about running a research farm, why onions and potatoes are his favorite challenging crops, and how real-world questions often inspire new studies.
