World Cup matches in those stadiums are played fully indoors due to the summer heat.AdvertisementAdvertisementAdvertisementThat necessitated grass grown in a cool climate to match the cooler indoor temperatures.”It seems a little strange that the grass is coming all the way from Colorado, but those buildings will be climate-controlled at 70 degrees throughout the whole tournament, so they needed a cool-season grass which thrives in our environment that’s near impossible to grow closer to where the venues are,” Green Valley Turf owner Joe Wilkins III told CNN.The family-owned business (founded in 1962) grows sod, turf and grasses, among other sod-related services, at its locations in Platteville and Littleton.AdvertisementAdvertisementAdvertisementThe grass for these World Cup venues was grown at the Platteville location and shipped off in May. Each pitch is 82,000 square feet and nearly 2 acres, requiring 24 semi-trucks to haul the grass to each venue.The grass is a proprietary mix of Kentucky bluegrass and perennial rye and was developed through a $5 million FIFA-funded research partnership between Michigan State University and the University of Tennessee.Combined, the three sites with Colorado-grown grass played host to nearly a quarter (24 out of 104) of the total 2026 World Cup matches.Chris Abshire covers high school and community sports for the Coloradoan.AdvertisementAdvertisementAdvertisementThis article originally appeared on Fort Collins Coloradoan: 2026 FIFA World Cup semifinals will be decided on Colorado grass
