Haitang Xifu has strong germination and fast growth. Pay attention to shaping and pruning. After defoliation in winter and before germination in spring, dead branches, diseased branches, weak branches, cross branches, overlapping branches, over-dense branches and other messy branches can be cut off. After flowering in spring, according to the needs of modeling, the excessively long branches can be appropriately shortened to promote lateral branches, increase the number of flower buds, and ensure a wide variety of flowers in the coming year. In addition, after germination in spring, too many buds with too dense and poor positions can be erased.

The modeling and processing of Xifu Begonia are often combined with binding and pruning, and the suitable processing period is from defoliation in winter to germination in spring. The growth of new branches in Meiyu period is mature, and the branches are more elastic, which is also suitable for cutting and binding processing. 2 ~ 3-year-old seedlings can be processed, which is highly plastic and easy to operate. It is better to use brown silk and metal wire together, and the trunk and big branches need to be properly tied, and all the branchlets should be trimmed and shaped. It is advisable to trim the branches and leaves into a natural crown, not to tie them too regularly. Begonia Xifu grows rapidly, so brown silk and metal wire should be removed in time to prevent damage to trees. It can be processed and made into various shapes such as inclined dry type, curved dry type, waterfront type, cliff type, double dry type and multi-dry type. It is advisable to choose a medium-deep glazed pottery basin or a purple sand pottery basin. The shape of the basin can be round, square, rectangular, etc., and it is better to compare the color and color of the basin. It likes fat and grows rapidly, so the pot should not be too small and too shallow. The planting and pot turning of Xifu Begonia bonsai should be carried out in February-March, or in late autumn. It is advisable to use loose and fertile garden soil, humus mixed with sand or chaff ash as matrix, and mountain mud can also be used. When the pot is put on or turned over, a small amount of decomposed cake crumbs and bone meal can be put at the bottom of the pot as base fertilizer. Young trees grow faster, and pots can be turned every 1 ~ 2 years, and old stumps can be separated by 2 ~ 3 years. When turning the pot, you need to trim the roots and branches to increase the appearance and maintain balance. Xifu begonia bonsai should be placed in a sunny, ventilated place. If the light is insufficient, it will grow poorly, the color is not bright enough, and it is not necessary to shade in summer. It is cold-resistant.

If it is heated indoors in winter, it can bloom in advance and leave the house in March of the following year.
