The Championships, Wimbledon, or simply Wimbledon, is the oldest tennis tournament in the world and is considered the most prestigious.[1][2][3] It has been held at the All England Club in the London suburb of Wimbledon since 1877. It is one of the four Grand Slam tennis tournaments, and the only one still played on grass courts. The tournament takes place over two weeks in late June and early July, culminating with the gentlemen's singles final, scheduled for the second Sunday. Each year, five major events are contested, as well as four junior events and four invitational events.
Nineteen courts are used at Wimbledon, and since 2001 they have all been sown with 100% Perennial Ryegrass, a grass native to Europe, Asia and northern Africa. Courts were previously 70% Ryegrass and 30% Creeping Red Fescue grass. The grass is hand-weeded and mowed to a height of 8mm everyday of the championship.[4][5]
