Virtually no fruit trees nowadays are grown on there own roots, but are grafted/budded onto a rootstock. This will then control the eventual size of the tree, although there are other factors to bear in mind that also affect tree growth. These include, variety, soil type and depth, location, and of course how the tree is trained and pruned. Therefore the following information can only be used as a guide.
