The history of pear pruning and training under the hot and dry conditions in South Africa is discussed. Due to the poor soils and the need for irrigation the move towards high-density plantings occurred with the continued use of the vigorous BP rootstocks. Planting densities have stabilized at ca. 4 x 1.5m (1667 trees/ha). Vigor in these plantings is managed through girdling and the manipulation of branching on young trees. These developments and technologies are discussed.
