For commercial purposes, including botanical evaluation, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting.
In addition to propagating trees on rootstocks designed to control size/vigour and confer disease resistance, grafting above the rootstock can be used to provide multiple cultivars of a single species, known as a family tree, or, within certain limits, cultivars of different fruit species on one tree, often known as a fruit salad tree.
An open-centred crown on a short trunk of less than 1 metre (3 ft 3 in). This is a traditional and popular form for apple trees. Bush trees are easy to maintain and bear fruit at a young age.
