Secondly, pear trees are suitable for a variety of bonsai models, such as straight dry, inclined dry, double dry, jungle, waterside, curved dry, lying dry and so on. Because the pear leaves are large, the crown is suitable for natural shape. In addition, the growth of pear trees is relatively strong, with large growth and vigorous development of top branches. It is necessary to control the growth of strong branches by means of leading and coring, which is conducive to the formation of short, compact, natural and beautiful crown and flower bud.
