Grass courts are a type of tennis playing surface made from natural grass. They are known for their fast playing conditions, which can lead to a low bounce of the ball. This surface is traditionally used in major tournaments, such as Wimbledon, where players must adapt their techniques to the unique characteristics of grass. Maintaining grass courts requires careful attention, including regular mowing, watering, and fertilization. The grass must be kept at a specific height to ensure optimal playing conditions. Grass courts are typically used during the summer months, as they can be affected by weather conditions and require more maintenance than other surfaces like clay or hard courts.
