For 1 month, the grass under the world’s best soccer players has to be pitch-perfect at 11 stadiums across the U.S.
That has meant hauling grass in dozens of refrigerated tractor trailers, laying pipes, and spreading sand across several existing fields before the new grass is rolled out, stitched together, and then kept green with LED lights in the indoor stadiums.
We’re LawnStarter, and the story of the World Cup grass started 4 years ago and with the cooperation of two U.S. universities charged by FIFA with growing the perfect grass.
We’ve got the story of how that grass was brought in and is being babied at each of the 11 stadiums ahead of the matches starting June 11.
You may have read local stories about World Cup grass at a stadium near you, but this is the big picture detailing the grass preparation at each stadium for football’s (or soccer’s) biggest competition.
By the way, FIFA’s rules extend to stadium names, which must be non-commercial, so we’ve listed the stadiums by their better known names with their World Cup names in parenthesis.

Natural Grass vs. Artificial Turf: Why FIFA Insists on Grass

Why are World Cup matches playd on natural grass and not artificial turf? FIFA’s Quality Program has very high test standards for ball rolling, bouncing, and shock absorption. Every stadium needs to deliver consistent playability across the tournament.
Why FIFA insists on grass:
- Player preference: Professional soccer players and their coaches prefer the feel and consistency of natural grass.
- Ball behavior: FIFA closely monitors how the ball rolls and bounces to ensure consistent ball behavior across all venues.
- Injury and performance: Research has shown differences in injury rates between playing on artificial turf and playing on real grass.
The Masterminds Behind the Turf: Michigan State and Tennessee
Growing world-class grass for stadiums in very different climates is a serious undertaking that requires academic precision.
Michigan State University’s Turf Management Program, under the leadership of Professor John “Trey” Rogers III, provided a source of both educational and research-based information to support the 2026 World Cup.
The University of Tennessee’s Center for Athletic Field Safety is well-known for its testing of field surfaces and for developing recommendations about which type of grass or root zone mixture may be used safely for athletes to play on and how the type of grass and root zone mixture can influence athlete injury/health and biomechanics.
Through their collaboration with each other, MSU and the University of Tennessee have developed turf systems that will allow the soccer ball to bounce, roll, and grip similarly across all 16 venues in the U.S., Canada, and Mexico.
They split the fields into two families, covering 88 miles of natural sod:
- Warm‑weather venues use Bermudagrass.
- Cooler and indoor venues use a mix of Kentucky bluegrass and perennial ryegrass.
For those cooler, indoor venues, the two groups chose an 84% Kentucky bluegrass and 16% perennial ryegrass combination when growing the turf using plastic sheeting. Through FIFA-funded trials, they determined this combination provided better quality and quicker establishment of sod than did individual Kentucky bluegrass.
Instead of planting grass in native soil and slicing off the roots, MSU and UT had farms grow it on a thin layer of sand with plastic sheeting. When the grass roots reach the plastic, they spread sideways and intertwine, forming a dense mat which can be rolled up like carpet without cutting the roots that can be easily shipped and installed.
The Turf Transformation: A Closer Look at Each U.S. Stadium
MetLife Stadium (New York/New Jersey)

Location: East Rutherford, New Jersey
Capacity: 82,500
World Cup matches: 8
World Cup surface: Bermudagrass, hybrid reinforced fibers
Grass provider: Carolina Green Turf Farm
Opened: 2010
For the World Cup finals, MetLife Stadium swapped out its artificial turf for a Tahoma 31 Bermudagrass field grown at Carolina Green Turf Farm in North Carolina. The existing turf infrastructure stays in place, but it’s now buried under roughly 2 feet of sand plus a full irrigation and vacuum‑ventilation system, with the warm‑season grass forming the top layer.
FIFA senior pitch manager David Graham summed up the stakes as crews stitched the rolls together on site: “It’s only justice that the best players on the planet hopefully get the best grass on the planet, and we’re trying to achieve that.”
Crews hauled in roughly 20 truckloads of sod that had been grown for about 10 months before installation. They used a “sewing machine-esque device” to stitch hybrid reinforcement fibers through the profile so the pitch can withstand 8 matches, including the final.
AT&T Stadium (Dallas Stadium)

Location: Arlington, Texas
Capacity: 94,000 (World Cup configuration)
World Cup matches: 9
World Cup surface: Kentucky bluegrass and perennial ryegrass mixture with hybrid reinforced fibers
Grass provider: Green Valley Sod
Opened: 2009
“Jerry World” replaced its Hellas Matrix Turf artificial grass with Helix Soft Top turf to install a natural-grass playing surface. The crews removed the existing turf and left the concrete subbase, on top of which they installed an entirely new irrigation system along with a new ventilation system.
Following this installation, about 10 inches of sand was placed atop the subbase to provide a root zone to create a FIFA‑spec root zone roughly 2 feet above the stadium floor. On top of the root zone is a Kentucky bluegrass sod grown in Colorado, rolled into large pieces and transported to AT&T Stadium.
A second, backup field was also planted in case there were issues with the primary field, due to it hosting the most matches of any World Cup venue: 9 games.
Mercedes‑Benz Stadium (Atlanta Stadium)

Location: Atlanta, Georgia
Capacity: 75,000
World Cup matches: 8
World Cup surface: Kentucky bluegrass, hybrid reinforced fibers
Grass provider: Green Valley Sod
Opened: 2017
Atlanta’s domed Mercedes‑Benz Stadium had one of the toughest turf swaps in the tournament. For the World Cup, crews tore out the existing turf and artificial surface starting in late January, then built a Permavoid-based system from scratch, topped with a Kentucky bluegrass/perennial ryegrass hybrid grass grown in Colorado.
According to UT researchers, this pitch was one of the most difficult World Cup pitches to maintain due to limited direct sunlight. The grass requires the use of a combination of LED grow lights, an extensive irrigation system, and a shallow root zone to provide consistent safety for players and good playing conditions.
NRG Stadium (Houston Stadium)

Location: Houston, Texas
Capacity: 72,000
World Cup matches: 7
World Cup surface: Kentucky bluegrass and perennial ryegrass mixture with hybrid reinforced fibers
Grass provider: Green Valley Sod
Opened: 2002
Under NRG Stadium’s turf is a concrete floor with channels for fake grass systems. The UT team chose a shallow system using Permavoid. These are strong plastic cells that store water and help the field drain.
Crews put the Permavoid right on the concrete. They covered it with a plastic woven sheeting to keep sand out of the cells, then added a deep-sand base and hybrid Kentucky bluegrass and perennial ryegrass.
The grass has been grown in the Denver area for the past 18 months, then shipped from Denver to Houston in massive refrigerated rolls before being stitched together into a continuous surface.
The stadium’s large roof severely limits how much sunlight reaches the grass. They brought large LED grow lights from Europe to assist in maintaining the health of the grass during the 7 World Cup matches that will be hosted there.
Arrowhead Stadium (Kansas City Stadium)

Location: Kansas City, Missouri
Capacity: 73,000
World Cup matches: 6
World Cup surface: Bermudagrass, hybrid reinforced fibers
Grass provider: Carolina Green
Opened: 1972
Arrowhead already uses natural grass. However, the field was still rebuilt to meet FIFA rules. For the tournament, Carolina Green from North Carolina provided Bermudagrass mixed with hybrid fibers. This is built on a stronger base of about 12 inches of sand over a gravel and pipe network with vacuum drainage, giving the surface a stable platform for the 6 matches.
To make the field the right size (115 by 74 yards), the Chiefs have removed seats and extended the playing surface into the corners, trading a small amount of capacity for a fully FIFA‑compliant pitch.
SoFi Stadium (Los Angeles Stadium)

Location: Inglewood, California
Capacity: 70,000
World Cup matches: 8
World Cup surface: Kentucky bluegrass and perennial ryegrass mixture with hybrid reinforced fibers
Grass provider: Desert Green Sod
Opened: 2020
To make natural grass work under SoFi Stadium’s translucent roof, FIFA and the UT/MSU team chose a Permavoid system stacked on top of the NFL turf, then covered with geotextile fabric, sand, and a hybrid Kentucky bluegrass/perennial ryegrass carpet reinforced with synthetic fibers.
SoFi tested a similar hybrid grass for a Concacaf Nations League test event and found that it “weathered the strain of 4 games in as many days.” This showed FIFA that the grass can survive 8 World Cup matches. With corners changed to meet FIFA’s field shape, the stadium perfectly shows how UT’s shallow system works inside a roofed stadium.
Hard Rock Stadium (Miami Stadium)

Location: Miami Gardens, Florida
Capacity: 65,000
World Cup matches: 7
World Cup surface: Bermudagrass, hybrid reinforced fibers
Grass provider: Miami Dolphins’ own private sod farm in Loxahatchee Groves, FL
Opened: 1987
Miami is one of the few World Cup venues that didn’t need to convert from turf to grass because it already uses Bermudagrass grown at a private sod farm in Loxahatchee Groves, roughly an hour north of the stadium.
Although the grass was specifically grown for the World Cup by FIFA and transported to Hard Rock Stadium and converted to a temporary warm-season grass surface for the 7 World Cup matches, the staff had to rely on grow lights as well as carefully manage water usage to ensure the color and density of the grass would remain uniform throughout the entire tournament.
Gillette Stadium (Boston Stadium)

Location: Foxborough, Massachusetts
Capacity: 65,000
World Cup matches: 7
World Cup surface: 365SS Kentucky bluegrass with hybrid reinforced fibers
Grass provider: Tuckahoe Turf Farms
Opened: 2002
For its World Cup matches, Gillette Stadium returned to real grass for the first time in almost 20 years. Gillette Stadium tore up the existing FieldTurf and gravel, rebuilt the new base with sand and other porous materials, and then installed a hybrid‑reinforced 365SS Kentucky bluegrass sod supplied by Tuckahoe Turf Farms in New Jersey.
The hybrid grass is about 95% natural and 5% synthetic fiber. The roots wrap the fibers together to provide stability to the surface.
Tuckahoe CFO Allen Carter shared with me the backstory:
“We have been working with FIFA and the stadiums on this project for about 4+/- years now. The sod itself is about a year old,” he explained, grown “on plastic on top of special pods that had computer‑controlled irrigation systems” so they could dial in nutrients, water, and FIFA‑spec topdressing from day one.
At Gillette, superintendent Ryan Bjorn said “the installation process was really intense,” and that “we’re really just focused on making sure that this field is as strong as it can be.”
Lincoln Financial Field (Philadelphia Stadium)

Location: Philadelphia, Pennsylvania
Capacity: 69,000
World Cup matches: 6
World Cup surface: Kentucky bluegrass with hybrid reinforced fibers
Grass provider: Tuckahoe Turf Farms
Opened: 2003
“The Linc” had been home to real grass, but it was renovated prior to hosting the 2025 Club World Cup, which opened up potential for a complete FIFA-recognized hybrid system for the 2026 World Cup.
For the Club World Cup, crews took out seats to widen the field to 115 by 74 yards. They installed a HERO Hybrid grass from Tuckahoe Turf Farms: a Kentucky bluegrass mix reinforced with synthetic fibers, grown on plastic for about a year before installation.
“We have grown the sod on plastic on top of special pods that had computer-controlled irrigation systems, then controlled the amount of nutrients, water, applied the FIFA spec topdressing throughout its growth period, and of course kept it mowed at the requested height,” Carter says.
“The hybrid infused system should help with the wear of the pitch,” as they prepare to host 6 games in a short amount of time.
Lumen Field (Seattle Stadium)

Location: Seattle, Washington
Capacity: 69,000
World Cup matches: 6
World Cup surface: Kentucky bluegrass and perennial ryegrass mixture with hybrid reinforced fibers
Grass provider: Moses Lake, Washington farm
Opened: 2002
In Seattle, the artificial grass hides under a layered natural‑grass system. For the 2026 World Cup, crews built the grass field right on top of the existing FieldTurf: 6 inches of sand and other base materials went down first, then a hybrid Kentucky bluegrass/perennial ryegrass sod from a Moses Lake, Washington, farm was rolled out on top.
FIFA turf expert Trey Rogers explained the logic to the Seattle Times:
“As long as we have 6 inches of sand over the top of the artificial turf, the player will not feel anything but a natural turf reaction.”
The new field will host a minimum of 6 World Cup events and then Sounders and Reign events before the grass is removed.
With long June days and cooler temperatures, Seattle may be able to rely more on natural sunlight than the domed U.S. venues. However, the shallow profile system still requires irrigation, drainage, and close monitoring to ensure the grass is World Cup-ready.
Levi’s Stadium (San Francisco Bay Area Stadium)

Location: Santa Clara, California
Capacity: 71,000
World Cup matches: 6
World Cup surface: Bermudagrass, hybrid reinforced fibers
Grass provider: West Coast Turf
Opened: 2014
Levi’s Stadium already uses high‑performance natural grass, and for 2026, is using Bermudagrass reinforced with stitched synthetic fibers supplied by West Coast Turf.
The fibers are stitched lightly so the grass can be removed easily after the tournament, but while they’re in place, they tie the roots together into a strong mat. With a traditional root base and a strong warm-weather grass, Levi’s Stadium can easily hold up to 6 matches.
Back in Your Own Backyard
The grass beneath the World Cup soccer players will get a lot of attention in coming weeks, but laying pipes and inches of sand and then a new layer of specially formulated grass? Don’t try this at home.
Just take care of your grass. Water it in the morning when needed and heeding any local watering restrictions. Block weeds or pluck them out when they spring up. Rake or blow leaves. And mow your grass regularly or hire a local LawnStarter lawn care pro to do it for you.
Oh, and you have the luxury of walking barefoot on your grass instead. Steer clear of zipping around on your grass with soccer shoes (with cleats) unless you’re attempting to aerate your lawn.
