Growing Giants in Pumpkin Country |


DeWITT – The Illinois grow a lot of pumpkins. Some feed giants on them.

The Heap Giant Pumpkin Farm in Minooka is hosting a statewide competition to honor the Greatest Giant, an event sponsored by the Illinois Giant Pumpkin Growers Association.

Last year, Henry Bartimus harvested the largest pumpkin, weighing 1,673 pounds. But even the giant Bartimus wasn’t close to the Illinois squash record of 2,145 pounds.

“It’s an addicting hobby,” said Bartimus, who lives in DeWitt.

“If you grow them for a few years, then you’re probably hooked for life. When you see a pumpkin put on two pounds in an hour, it’s just amazing. Many will gain 40 to 50 pounds each day for three weeks and then begin to decrease.

The pumpkin lover said growers from all walks of life embark on growing a giant when photos or stories spark their interest. “Many just have a love of pumpkins,” he said.

Bartimus estimated that around seven producers regularly compete for the state crown. To offer prizes to the bigger pumpkins, the State Producers’ Association auctions giant pumpkin seeds from December to February, with many online auctions at

“A lot of people are very generous and can pay $ 1,000 for a seed, but you can buy seeds with the potential to grow 2,000 pound pumpkins for $ 35 to $ 100,” Bartimus said. “Seeds that have already grown to 2,000 pounds and more are called proven seeds and can sell for between $ 100 and $ 350, or even $ 600. Some groups sell seeds year round, usually between $ 35 and $ 70.

“If you look at the genetics of the seed, you might be able to ask the grower, and he can give you seeds if you pay the shipping costs,” he added.

Growing a Colossus requires a lot of TLC.

Seeds are usually started indoors around April 8 before being placed outdoors in huts with heaters and fans. Many producers use underground heating cables, Bartimus said

“We try to pollinate our plants from June 15 to July 1. At this point they have reached 30 feet wide and 18 feet long,” he said.

Plants are pruned to limit their size. When the pumpkin is 30 days old, the grower stops all growth of the vine, so all of the plant’s energy goes into the pumpkin.

If it isn’t raining, a grower will provide 50 to 120 gallons of water per day for every 1,000 square feet of plant. Only one pumpkin is grown on each plant. Growers will work one to eight hours a day on a single plant, according to Bartimus.

One of the most important factors is soil testing. The best growers add nutrients throughout the growing season. Bartimus fertilizes his plants daily, adding as little as a single teaspoon. It uses a lot of algae and humic acid.

The main pests are squash vine borers, cucumber beetles and squash bugs. Powdery mildew can be a problem.

“You almost have to work on it every day if a problem starts out like disease or rot,” he said. “Every minute counts to master it. “

Giant pumpkins don’t like to be too hot or too cold, preferring temperatures between 75 and 80 degrees.

“Many growers use some type of shade cloth or automatic misting systems to cool the plant with multiple fans,” the grower said. “Excessive rains slows growth due to the low oxygen level in the soil and the vines can rot because of this as well. Much of the United States has had trouble growing giants this year. “

Pampered pumpkins can appear in commercial displays or be carved by artists, fall from cranes at fun events, feed zoo animals, or simply sit in the gardens of their proud growers.

Bartimus advised interested growers not to be shy and bring pumpkins of all sizes to weigh.

“We don’t laugh at you or we don’t laugh at you. It’s a great place to meet producers and ask questions, ”said the veteran producer. “Sometimes getting a pumpkin of any size to survive until the end of a season can be a challenge, and the best growers know it.”

When asked if growing giant pumpkins was a hobby, an advocation, or a passion, Bartimus replied, “All of them. For me and for many other producers this is more of a challenge against yourself than against the competition. But yes, we all love to win.
