There’s a saying in corn country: “Knee high by the Fourth of July.” The adage refers to a farmer’s goal for their vegetation if they hope to make the October harvest. And while most Midwesterners are familiar with the axiom, Tim Fitzgerald knows the folksy refrain misplaced its relevancy decades ago.
“That hasn’t actually been lawful since prior to fashionable fertilizers. Nowadays corn is about six toes or taller by the Fourth of July,” Fitzgerald, a farmer in Lafayette, Indiana, tells Popular Science.
Fitzgerald, nevertheless, aloof adheres to the classic timeline. That’s because his farm isn’t any longer strictly in the agricultural industry. After a 22-year career in industrial trade prove designing, Fitzgerald has since spent nearly that prolonged overseeing “northwest Indiana’s largest corn maze,” Exploration Acres.
Commercial farmers often accomplish planting by mid-May, nonetheless Fitzgerald’s team starts sowing the first week of June. By the time Fourth of July fireworks are interesting overhead, Exploration Acres’ corn is inching towards your waist. The strategy isn’t out of a reverence for tradition, nevertheless.
“We plant later because we want to have corn that’s as inexperienced as doable for as prolonged as doable. We also exhaust really late-maturing corn that matures at around 113 days,” he explains.
Once Fitzgerald opens the maze in September, its winding walls are successfully above the heads of the estimated forty five,000 seasonal friends that tear its miles of pathways. Nonetheless guaranteeing the lawful peak is easiest one part of the monthslong mazebuilding endeavor—a direction of that’s equal parts logistics, agricultural science, technological coordination, and artistry.

The olden days
Fitzgerald was already successfully-suited for the labyrinth industry when he transitioned careers and converted his family’s dilapidated farm into a regional attraction in 2008. At some point of his time away, nevertheless, noteworthy of the nearly century-mature property had started to collapse.
“It was literally falling apart,” he remembers.
As the agricultural industry continued its shift away from smaller farms to corporate megafacilities, places like Exploration Acres transitioned into the agritourism industry. These repurposed farms offered faculties seasonal educational opportunities, as successfully as the chance to flip fields into symbolic celebrations of America’s favorite cash gash.
Ahead of fall 2008, Fitzgerald reached out to Shawn Stolworthy at MazePlay, an Idaho-based company specializing in all issues corn maze, to plan out his first labyrinth. The maze designs at Exploration Acres today range anywhere from 18 to 23 acres looking out on the season, nonetheless Fitzgerald settled on a comparatively modest 15-acre arrangement for the inaugural year.
Supreme as farming has modernized over time, so has the direction of that goes into preparing a corn maze. As Fitzgerald explains, the early strategy relied on a subtractive approach. The first step was to plant and grow your corn at the appropriate time. Meanwhile, Fitzgerald decided and created an artistic theme himself. Once the pathways were finalized, it was a matter of creating the maze’s vector recordsdata in Adobe Illustrator. No, really.
“MazePlay developed proprietary software that enables you to decrease mazes the usage of GPS. At that time, it was all vector-based,” he says. “You were basically creating a heart line the place the paths would be, and then you faded steer-track expertise on tractors that allowed the tractors to autonomously apply the vectors. You dwelling your flooring race, and it goes.”
At some point of that era, a tractor’s turning radius and other factors restricted the maze’s complexity. In an ideal world, Fitzgerald would have simply planted corn easiest the place wanted and left the relaxation barren for friends to walk. It took nearly a decade for the expertise to catch up with that idea. Enter: SpeedTubes.

‘Printing’ pathways
SpeedTubes are designed so farmers can customise the spacing between vegetation as a way to increase development while minimizing the chance of disease. Nonetheless Fitzgerald and his collaborators saw another exhaust for them.
“We wouldn’t have to make exhaust of as noteworthy corn because we wouldn’t have to plant the entire area. We’ll loyal plant corn the place we need it,” he says. “Basically what they attain is they have this cramped vacuum servo on it that will encourage onto the cramped grain of corn unless you want to plunge it exactly.”
Exploration Acres began experimenting with the contemporary strategy in 2017. The results were immediately noticeable. Instead of ten seed bags, the SpeedTube-assisted accomplish required easiest seven. (A single bag of seed can plant around two-and-a-quarter acres of corn.)
Gone were the days of tractors plowing by means of a area to carve out walkways. Now, they simply roll from one aspect of the acreage to another, flip, and repeat the direction of. With the accomplish keyed into the onboard software, the race tubes did the relaxation by dropping seeds easiest the place necessary.
“Everytime any of these rows intersect with a [maze] path, the race planter will flip off unless it gets to the other aspect and then it turns back on. There are actually these cramped LED lights on the back of the hoppers going red-to-blue, red-to-blue,” Fitzgerald says.
He likens the contemporary approach to the moment all individuals swapped out their dot-matrix printers for inkjets. Not that the first year wasn’t without complications.
Trial and error
“It’s really heavenly uncomplicated expertise, nonetheless what we ran into in 2017 was each time the tractor made a flip, it reversed path,” he recalls.
This meant that upon its return runs,
