Its flowers are red, yellow and white, and the red one is particularly expensive. It's called Zhu Jin. In Donghai, China, there is a hibiscus tree. This flower is radiant with leaves like mulberries.

Cultivation method of hibiscus flowers
Changing pots and pruning
The soil for potted plants should be loose and fertile sandy loam, and the pots should be changed before moving in early spring and April every year.
There are three things to do when changing pots: first, put in new culture soil; The second is to cut off some fibrous roots that are too dense and curly; The third is to apply plantar fertilizer and slightly add phosphate fertilizer to the pelvic floor. In order to maintain a beautiful tree shape and a large number of flowers, according to the characteristics of strong germination ability of hibiscus, pruning and shaping can be carried out before and after leaving the house in early spring. Except for 2-3 buds at the base, all the upper branches were cut off. Pruning can promote the new branches to grow more vigorously and the plant shape is beautiful. Water and fertilizer should be properly controlled after pruning, because the consumption of aboveground parts is reduced.
maintenance management
Zhu Jin is a positive tree species and should be moved outdoors in early May and placed in a sunny place. At this time, it is also the growing season of Fusang, so we should strengthen the management of fertilizing water, loosening soil and pulling weeds. Apply dilute liquid fertilizer every 7- 10 days, and water it according to the wet and dry conditions of the basin soil. Too dry or too wet will affect flowering.
Insufficient light, buds are easy to fall off, flowers shrink, and the sunshine should not be less than 8 hours a day. Fusang has a great demand for fertilizer, so it should be supplemented in time when it is cultivated. Potted hibiscus usually leaves the house in April. Before going out, change pots, trim them properly and keep a beautiful crown. During the growing period, there should be enough water, no water shortage and no waterlogging. Usually, water should be used once a day, once in the dog days and once in the morning and evening. The ground is often watered and humidified to cool down to prevent the tender leaves from burning and the flowers from falling prematurely. After cooling at 10, move it into the greenhouse and keep the temperature above 12℃. Management should be cautious after autumn, and pay attention to less fertilization in the later period to avoid sprouting autumn shoots. Autumn bamboo shoots are tender and weak in cold resistance, and will be frozen when the weather is cold.
Freezing and keeping warm
Zhu Jin is not frost-tolerant, so it must be moved indoors to keep warm after the first frost and before beginning of winter. The overwintering temperature shall not be lower than 5℃ to avoid freezing injury; Not higher than 15℃, so as not to affect dormancy. Poor dormancy leads to poor growth and flowering in the following year. All furniture rooms with good heat preservation conditions facing south can survive the winter, and can be covered with paper or plastic film for heat preservation when the weather is cold. Move the house for the first time every day, open the window for ventilation, pay attention to the dry and wet changes of the basin soil, and water it properly. In the coldest days, watering can prevent freezing injury, but fertilization should be stopped.
