'They’re closer to architecture than landscaping': inside Walt Disney World’s eight-month process to build EPCOT’s Flower & Garden Festival topiaries
"It takes close to eight months to produce the topiaries," explained Debbie Mola Mickler, area manager at Disney's Horticulture — for installations that were on display for just a few weeks.
On that clock, Disney's horticulture team is likely already deep into next year's lineup — even though this year's International Flower & Garden Festival at EPCOT only wrapped June 1. Mola Mickler oversees production of the living character sculptures that define the festival at Walt Disney World in Orlando. What look like decorative topiaries from a distance reveal themselves up close as something far more complex.
Underneath, engineered steel frames, a moss growth medium, and tightly integrated irrigation work together so that whether it's Mickey, Buzz, Lightning McQueen, or any other character, the topiary presents itself exactly as it should. They're closer to architecture than landscaping, and the timeline to build one reflects that.
That timeline starts long before any planting begins. Disney's horticulture team works directly with Walt Disney Imagineering to decide which characters can even be translated into living structures — a process that blends creative direction with real-world constraints like weight, scale, and maintenance. Once a character is selected, Mola Mickler goes straight to the source and thinks about scale — how big the topiaries need to be, and what plant material can tell that story.
From design, Disney's digital team produces a maquette — a small 3D-printed physical model of each topiary — that serves as the reference guide for everything that follows, from fabrication through final trimming.
That translation from screen to structure is where Disney's topiaries stop being just landscaping and become systems design problems. "Our Imagineers are so creative, they've pushed us towards getting these topiaries with more movement," she explained. The dresses have folds; legs may be bent like a character is mid-dance. That push toward motion and expression has forced a redesign of how internal structures are built — especially as characters become more dynamic and less symmetrical.
Once a design is approved, Disney builds a full production pipeline that starts with digital modeling and ends with custom steel fabrication. "You can't just go to the yellow pages and find a welder to make the frame," Debbie said.
Each topiary begins as a custom-engineered stainless steel structure designed to support weight, shape, and long-term outdoor exposure. Built into each frame are engineered pick points — load-bearing anchors that allow heavy equipment like cranes and forklifts to position the finished topiaries into their beds in the park. Some characters arrive in multiple pieces and are assembled on-site.
Once the steel frame is in place, it's filled with sphagnum moss, which acts as the primary growth medium. For larger characters, Disney builds a secondary cage of chicken wire inside the frame first — since plants only need about two to three inches of growing area, the inner cage reduces the amount of moss required while maintaining the structure's shape.
The moss retains moisture, supports plant plugs, and forms the core structure that everything else grows into. Built into each frame is a segmented irrigation system that allows Disney to control water distribution at a surprisingly granular level.
"We can do arms, we can do the head, we can do the feet," Debbie said. "And then we'll turn it off as needed." That segmentation isn't just for efficiency — it's environmental control. Florida's climate can shift rapidly, and different parts of a topiary may require different hydration levels depending on sun exposure and airflow.
As the plants grow in, the maquette becomes the trimming guide — helping maintain pose accuracy and character shape across months of active growth before the festival opens.
Behind the scenes, Disney operates continuous environmental monitoring across 12 greenhouse facilities, each subdivided into controlled environments that simulate different growing conditions depending on plant type and stage. Debbie described automated alerts that notify her directly if temperatures fall outside safe ranges — a system her team relies on enough that they refer to themselves as "weather watchers."
The foundational methods, though, have deep roots. "Many years ago when I first started in Disney horticulture, we did not have sphagnum topiary," Debbie said. "We only had woody topiaries with single shrubs being trained in a frame, and it can take seven to 10 years to grow one."
Those traditional systems, still used at Disneyland, rely on shrubs trained over lightweight frames and take several years to mature. At EPCOT, the sphagnum system enables faster production cycles and far more expressive designs — but still requires nearly a year of preparation per installation.
Some heritage pieces remain in rotation, including a more than 50-year-old elephant topiary originally built for Magic Kingdom that now makes a special appearance just for Flower & Garden in EPCOT's United Kingdom Pavilion.
Modern festival builds, meanwhile, sit at the intersection of horticulture and fabrication engineering. Materials like palm fiber replicate textures such as Woody's hat and boots; coconut coir matting handles facial detailing. Props like belt buckles and sheriff badges are 3D printed and integrated directly into the structures.
Even animation principles feed into final assembly. "We want to make sure the eyes are always looking at the guest when they take a picture," Debbie said.
It's that kind of detail — designed not just to be seen, but to be experienced — that makes the topiaries something more than seasonal decoration. They're living installations built to hold up across an entire festival, in Florida heat, one carefully engineered character at a time.
