Contained in the making of a world-class corn maze

There’s a saying in corn nation: “Knee excessive by the Fourth of July.” The adage refers to a farmer’s aim for his or her crops in the event that they hope to make the October harvest. And whereas most Midwesterners are acquainted with the axiom, Tim Fitzgerald is aware of the folksy chorus misplaced its relevancy a long time in the past.

“That hasn’t truly been true since previous to fashionable fertilizers. These days corn is about six ft or taller by the Fourth of July,” Fitzgerald, a farmer in Lafayette, Indiana, tells Fashionable Science.

Fitzgerald, nevertheless, nonetheless adheres to the basic timeline. That’s as a result of his farm is not strictly within the agricultural enterprise. After a 22-year profession in industrial commerce present designing, Fitzgerald has since spent almost that lengthy overseeing “northwest Indiana’s largest corn maze,” Exploration Acres. 

Business farmers usually end planting by mid-Might, however Fitzgerald’s crew begins sowing the primary week of June. By the point Fourth of July fireworks are shimmering overhead, Exploration Acres’ corn is inching in direction of your waist. The technique isn’t out of a reverence for custom, nevertheless.

“We plant later as a result of we need to have corn that’s as inexperienced as potential for so long as potential. We additionally use actually late-maturing corn that matures at round 113 days,” he explains.

As soon as Fitzgerald opens the maze in September, its winding partitions are effectively above the heads of the estimated 45,000 seasonal guests that trek its miles of pathways. However guaranteeing the correct top is just one element of the monthslong mazebuilding endeavor—a course of that’s equal components logistics, agricultural science, technological coordination, and artistry.

The olden days

Fitzgerald was already well-suited for the labyrinth enterprise when he transitioned careers and transformed his household’s dilapidated farm right into a regional attraction in 2008. Throughout his time away, nevertheless, a lot of the almost century-old property had began to crumble.

“It was actually falling aside,” he remembers.

Because the agricultural trade continued its shift away from smaller farms to company megafacilities, locations like Exploration Acres transitioned into the agritourism enterprise. These repurposed farms provided colleges seasonal academic alternatives, in addition to the possibility to show fields into symbolic celebrations of America’s favourite money crop.

Forward of fall 2008, Fitzgerald reached out to Shawn Stolworthy at MazePlay, an Idaho-based firm specializing in all issues corn maze, to plan out his first labyrinth. The maze designs at Exploration Acres right now vary wherever from 18 to 23 acres relying on the season, however Fitzgerald settled on a relatively modest 15-acre association for the inaugural yr.

Simply as farming has modernized over time, so has the method that goes into making ready a corn maze. As Fitzgerald explains, the early technique relied on a subtractive strategy. The 1st step was to plant and develop your corn on the applicable time. In the meantime, Fitzgerald determined and created a creative theme himself. As soon as the pathways had been finalized, it was a matter of making the maze’s vector recordsdata in Adobe Illustrator. No, actually.

“MazePlay developed proprietary software program that allows you to lower mazes utilizing GPS. At the moment, it was all vector-based,” he says. “You had been mainly creating a middle line the place the paths could be, and you then used steer-track expertise on tractors that allowed the tractors to autonomously comply with the vectors. You set your floor velocity, and it goes.”

Throughout that period, a tractor’s turning radius and different components restricted the maze’s complexity. In a great world, Fitzgerald would have merely planted corn solely the place wanted and left the remaining barren for guests to stroll. It took almost a decade for the expertise to meet up with that concept. Enter: SpeedTubes.

‘Printing’ pathways

SpeedTubes are designed so farmers can customise the spacing between crops as a method to enhance progress whereas minimizing the danger of illness. However Fitzgerald and his collaborators noticed one other use for them.

“We wouldn’t want to make use of as a lot corn as a result of we wouldn’t must plant your complete area. We’ll simply plant corn the place we’d like it,” he says. “Mainly what they do is that they have this little vacuum servo on it that may maintain onto the little grain of corn till you need to drop it exactly.”

Exploration Acres started experimenting with the brand new technique in 2017. The outcomes had been instantly noticeable. As an alternative of ten seed baggage, the SpeedTube-assisted design required solely seven. (A single bag of seed can plant round two-and-a-quarter acres of corn.)

Gone had been the times of tractors plowing by a area to carve out walkways. Now, they merely roll from one facet of the acreage to a different, flip, and repeat the method. With the design keyed into the onboard software program, the velocity tubes did the remaining by dropping seeds solely the place mandatory.

“Everytime any of these rows intersect with a [maze] path, the velocity planter will flip off till it will get to the opposite facet after which it turns again on. There are literally these little LED lights on the again of the hoppers going red-to-blue, red-to-blue,” Fitzgerald says.

He likens the brand new strategy to the second everybody swapped out their dot-matrix printers for inkjets. Not that the primary yr wasn’t with out problems.

Trial and error

“It’s actually fairly easy expertise, however what we bumped into in 2017 was at any time when the tractor made a flip, it reversed route,” he remembers.

This meant that upon its return runs, all the things was off by a number of ft.

“We had a blurry picture,” says Fitzgerald.

In fact, with the seeds planted underground, the employees didn’t instantly understand the problem. It was solely after a couple of weeks when the primary child corn sprouts emerged that they observed one thing amiss.

“It created an enormous headache,” he remembers.

They finally fastened the skewed design by truly planting extra seeds at an offset distance. They then returned with the trusty tiller and eliminated the additional stalks they didn’t want.

“You’re Fashionable Science. A part of science is trial and error. You will have a speculation and also you attempt to show and disprove. So that you study issues,” he says with amusing.

With a helpful lesson discovered, Fitzgerald put the brand new system to the take a look at the next yr and made nationwide information. Keep in mind that Netflix-approved Stranger Issues corn maze in 2018? That was Exploration Acres.

“I truly needed to signal an NDA, and so they shared with me what the season was going to be about, so we initially designed a complete maze for the following season,” he says.

Different mazes have celebrated the Apollo moon touchdown, dinosaurs, zombies, pirates, and different topics. This yr marks Lafayette’s bicentennial, so Exploration Acres partnered with metropolis officers to design an ode to the city. Guests this season will wander by portraits of the city’s founder, William Digby, in addition to its Revolutionary Warfare namesake, the Marquis de Lafayette. Though 2025’s theme required a bit extra outdoors tips, there are some normal guidelines Fitzgerald retains in thoughts when sitting all the way down to plan out his subsequent creation.

“I at all times attempt to have a superb composition—a superb use of optimistic and unfavourable areas,” he says.

It’s additionally vital to rotate the maze between fields. Fitzgerald’s farm consists of 4 maze areas, at all times close to their annual pumpkin patch. When not used for the orange gourds, the employees additionally plant soybeans for the free nitrogen they produce and thus minimizing the necessity for fertilizer.

Mapping a route ahead

After almost 20 years in operation, Exploration Acres has the maze course of all the way down to a science. However its proprietor is aware of there’ll at all times be a must experiment with new approaches. It’s inevitable because the local weather disaster continues to make its presence felt. Usually, timber on the farm have already littered the grounds with walnuts, hickory nuts, and acorns, however this yr’s prolonged drought has dried the bottom and made it a haven for pests.

“I’ve obtained rodent strain,” Fitzgerald says. “I’ve obtained voles and moles and chipmunks and squirrels. All of them digging up and consuming my tulip bulbs. There’s nothing else for them to eat, it’s been so dry.”

Then there’s the warmth. The primary few weeks of the 2025 season have seen a dramatic drop in attendees resulting from record-setting temperatures.

“That’s been a significant change since we began in 2008,” he explains. “Again then, individuals would come out and so they’d drink scorching cocoa. They’d put on mittens and gloves and a winter jacket—it’d be 38 or 40 levels out and blustery.”

Fitzgerald has even jettisoned the hay bales that usually line their wagon rides. Whereas straw is simple to sit down on for those who’re carrying lengthy pants, it’s a a lot itchier expertise in shorts.

“The worth of straw’s gone up, hardly anybody crops wheat round right here anymore. So I simply stated, ‘To heck with it,’ and put in benches within the wagons. A whole lot of issues have needed to change with time,” he says.

There may be, nevertheless, at the least one element you may depend on at Exploration Acres’ gigantic corn mazes. Regardless of how difficult the paths could appear, there’s no must get spooked if you end up rotated among the many pathways. 

“We hardly ever get anybody misplaced in there. We now have an emergency path that strains the perimeter with a number of exits,” Fitzgerald assures.
