Wimbledon's Courts Stay Green Amidst London Heat Wave

As London experienced a record-breaking heat wave last week, turning much of its landscape brown, Wimbledon's tennis courts maintained their signature lush green appearance. This feat is achieved through extensive preparation and continuous monitoring by a dedicated team of groundskeepers.

Neil Stubley, the head of courts and horticulture at the All England Club, relies on insights from nearly 40 years of grass species research. This research focuses on identifying drought-tolerant and hard-wearing varieties, with perennial ryegrass being sown on tournament courts since 2001. The team utilizes data from approximately 25 weather apps and employs probes to measure soil moisture, directly influencing surface hardness and grass cover.

Even as temperatures in Britain reached unprecedented highs, the courts benefited from cooler overnight temperatures, which allowed them to recover. While spring was drier than usual, impacting water supply in Greater London, Wimbledon organizers prioritize conservation efforts, exploring water recapture and reuse systems. The unique challenge of maintaining a live grass surface, unlike the hard or clay courts of other Grand Slams, requires constant data analysis and microclimate management for each court.

The courts also face damage from player sliding, described as a 'cheese grater' effect on the grass. Stubley's team continuously analyzes data, including moisture and hardness readings, even counting grass blades, to make micro-adjustments to watering. This meticulous approach ensures that Wimbledon's iconic courts are ready for play, despite the ongoing challenges of climate change and player impact.
