Similar to putting greens, grass courts are fairly rare because of their tremendous amount of upkeep. Only a few private clubs can afford to maintain grass courts. The Wimbledon Tennis Tournament is played on a grass court. Red clay surface courts are made from crushed brick that is packed to make a good surface for tennis play. The French Open in Paris is played on red clay courts.
Green clay is a natural clay, which is packed to make a subsurface, then covered with a topping.
This is a highly popular style in the eastern and southern United States. Player injuries are less frequent on natural clay courts. Clay courts do require regular watering, compacting and brushing. These courts should be constructed in an area where the humidity is high so they can absorb extra moisture. Drainage is also an important.
