(2) moisture. Love wet water, resist drought, water from spring to summer 1 ~ 2 times; After autumn, you can water it again before winter. Keep the basin soil moist at ordinary times.
(3) illumination and temperature. Like light, like warm and humid climate, but also a little tolerant of semi-shade. It should be planted in the leeward and sunny places. Cold tolerance, drought tolerance, suitable growth temperature 15 ~ 25℃, low temperature tolerance-15℃, semi-shade tolerance. In the area north of the warm temperate zone, you can keep the temperature around 0℃ for the winter by moving indoors.
(4) plastic trimming. Strong germination and pruning resistance. Trunk pruning and plastic surgery are generally used. Select 3 ~ 6 main branches and cut them for 3 years. While cultivating the main branches and side branches, we should slow down the vigorous flower branches that were in full bloom that year and not cut them. In the second year, all the luxuriant and robust flowers sprouted on the tree were thinned out, leaving only the short flowers blooming. Can control the tree potential and promote flowering. After cutting off the peripheral branches, three strong branches can germinate under the incision. Among them, branches with better positions are selected and cut short at 1/2. After cutting, external buds are left, and competitive branches are thinned out.
(5) reproduction. It can be propagated by sowing, cutting and grafting. Cutting in April can be combined with pruning and shaping. Cuttings are thick wooden branches with a length of 10 ~ 12cm. They are harvested in the open air in red soil or sandy soil and watered once every morning, which is very easy to survive.
(6) pest control. The main pests and diseases are: yellow thorn moth, caterpillar, aphid, fly maggot, round shield scale, soot disease. Paying attention to keeping the cultivation and maintenance environment ventilated can reduce the occurrence of pests and diseases.
