1, temperature conditions
Illicium verum likes a cool growth environment, and the temperature is suitable to be between10-25℃, usually18-20℃ during the day and10-12℃ at night, which can keep good growth indoors. It should be noted that the persistent high temperature can easily make its blades thinner and bigger, and start to sag. The octagonal gold plate is cold-resistant, and it can safely overwinter when the temperature is above 7℃.
2. Lighting conditions
Illicium verum is a semi-negative plant, which has strong tolerance to shade, but avoids strong light. Suitable for greenhouse cultivation, except in winter, shading should generally reach more than 60%, especially pay attention to direct sunlight in summer and strengthen shading. On the other hand, if there is insufficient light for a long time, the leaves will become small. Get more sunshine in winter.
3, water and fertilizer situation
In the growing period of Illicium verum, that is, April 4- 10/0, thin liquid fertilizer is applied once every two weeks, and fertilization is stopped after October. Water frequently in hot season to keep the soil moist. At the same time, spray water on the leaves and surrounding areas to improve the air humidity nearby. After October, we should gradually reduce watering and control watering.
4. Soil requirements
It is suitable to choose fertile and loose soil with good drainage. Pot soil can be mixed with 3 parts of garden soil and 1 part of chaff ash, and a little bit of base fertilizer.
5. Change pots and turn over the soil
In the process of breeding, the pots should be changed every1-2 years, usually in March and April. When turning over the soil and changing the basin, base fertilizer should be put into the basin bottom.
matters need attention
1 disease
Illicium verum Bunge has bituminous coal disease, leaf spot disease and yellowing disease. Leaf spot disease mostly occurs in summer and can be controlled by thiophanate methyl or carbendazim. Yellowing can be prevented by foliar spraying with ferrous sulfate water.
2. Pests
Insect pests mainly include aphids, scale insects and red spiders. Generally, scale insects can be controlled by rapid vector killing, aphids can be controlled by shovel, and red spiders can be controlled by dicofol.
