The Big Science Behind Giant Pumpkins

Every fall, thousands of visitors swarm the giant pumpkin exhibit at the N.C. State Fair. But what does it take to grow a pumpkin big enough to wow the crowd?

In a recent episode of WUNC’s podcast The Broadside, listeners get a look inside the art, science and sheer hustle of growing a great pumpkin. From horticultural research at NC State to hands-on work by Extension experts and dedicated growers, it’s a story of curiosity and community.

A young girl sits on a giant pumpkin in the back of a pickup truck at an NC State Extension research plot in the North Carolina mountains, surrounded by vines and other foliage, showing the scale of the pumpkin.
This mountain-grown giant pumpkin came from a plot supported by NC State Extension.

Jonathan Schultheis, NC State Extension horticulture specialist, breaks down what it really takes to grow a pumpkin that tips the scales. Randy Collins, director of N.C. Cooperative Extension's Graham County Center, shares how our experts support growers statewide and troubleshoot timely challenges. And longtime local growers offer a peek into the mix of patience, strategy and friendly competition that fuels the giant-pumpkin community.

Whether you’re a weekend gardener, a fair-goer or just curious how something ordinary becomes extraordinary, this episode digs into the skill and science behind supersized pumpkins — with Extension experts helping explain what’s really going on.
