Watch the install of Ai Weiwei’s Tree, 2010 in the Turbine Hall at Tate Modern. Tree is made from numerous dry branches, roots and trunks from different species of trees that the artist gathered from across his native China. Although it mimics the form of a real tree, the visible joins make it apparent that it has been made by piecing together individual elements. Tree celebrates the Chinese custom of displaying distinctive tree trunks and curiously shaped roots as home decorations. The dry and ‘dead’ tree sections that Tree is made from also draw attention to the country’s rapid urbanisation and economic growth, which have resulted in damage to the natural environment and the suppression of traditional culture.
