Illinois isn’t just the Land of Lincoln; it could also be called the Land of Pumpkins. The state grows more than a quarter of the pumpkin crop in the U.S. and the USDA says most of that becomes food products.

Farmers around one particular Illinois town are likely the reason you have pumpkin pie to enjoy for Thanksgiving, and the weather there is a big factor in the supply of canned pumpkin.

What You Need To Know

  • Libby's produces the vast majority of the canned pumpkin consumed in the U.S.

  • Most of the farms that grow pumpkins for canning are in central Illinois

  • Pumpkins do well in warm and dry conditions, but wet seasons are a problem

  • Climate change is likely causing heavier rainfall in the Midwest

Morton, a town of 17,000, is situated a couple of hours southwest of Chicago, just outside Peoria. It's here you'll find Libby’s pumpkin facility. The Nestlé-owned company produces more than 80% of the canned pumpkin eaten in the U.S. each year and farmers grow most of those pumpkins in and around Morton.

Pumpkin weather

Just like any crop, weather is hugely important.

Pumpkins can withstand drought relatively well, which is what happened in the parched Midwest in the summer of 2012.

Wet weather, though, is a much bigger problem. It can limit pumpkins’ growth or leave them rotting in fields and sometimes makes the soil too soft for tractors to go in and harvest.

Central Illinois dealt with too much rain in the fall of 2008 and summer of 2015 when double the average amount fell both times. Shortages of canned pumpkin followed.

What about this year? This season in central Illinois was a little on the dry side; the weather observer in Morton logged about 16.5 inches of rain from May through September, more than 3 inches below average. The average temperature over the summer was a little warmer than normal.

So you shouldn't have any problems finding those pumpkin pie fillings this holiday season.

Climate change

The Midwest has gotten wetter in recent years as heavy rain events become more frequent. Scientists have tied that trend to climate change.

Paul Bakus, then-president of corporate affairs at Nestlé, told Scientific American in 2015 that he looked at climate change as the reason for that year’s poor weather and that climate change that would continue to deeply affect their business in the future.

Sustainability efforts

Even though pumpkin farmers can’t keep unwanted downpours away, they can alter their farming techniques. That’s exactly what some of them are doing on thousands of acres near Morton.

They’re trying out regenerative farming practices that have better environmental outcomes like lowering emissions, improving soil quality and attracting pollinators.
