Potted lilies need to choose the right medium, which can be made by mixing garden soil, cinder and fine sand, or adding some rotten leaf soil. The bottom of the flowerpot is paved with broken tiles as the drainage layer. When the medium is put in, some basic fertilizer can be added appropriately.
The growth of xiaolihua needs sufficient light. It's better not to spend less than 6 hours every day in order to avoid poor growth. In spring, autumn and winter, direct light can be given to dahlia, but in high-temperature summer, direct light should be avoided as much as possible, and it can be placed in a bright place for maintenance. In terms of temperature, xiaolihua likes a cooler environment and is afraid of heat. When it's hot and sunny in summer, it's necessary to properly shade it or spray water to cool it. It is also not frost resistant. When the temperature drops below 10 ℃, it will go to sleep. The suitable growth temperature of lilies is between 15 ℃ and 28 ℃.
Xiaolihua does not have high requirements for water and fertilizer. Generally, water more in summer, less in spring and autumn, keep the basin soil dry and wet, avoid water accumulation in the basin, and pay attention to drainage in rainy seasons. In the growing period, we should apply a thin liquid fertilizer every 10-15 days. When flowering, we should apply 1% - 3% potassium dihydrogen phosphate to promote flowering.
In order to control the flower type and promote flowering, we can prune it in the process of cultivation. In the growth period, often pick the heart, can make the lilies more branches, branches thick. In the process of growth, some dead leaves and diseased leaves can be cut off to promote the healthy growth of lilies.
Most of the propagation of lilies are by means of individual propagation and ball propagation, or by cutting.
The diseases and insect pests of Dahlia are not common, but there are the hazards of powdery mildew, brown spot, virus disease and moth larvae, which need to be found in time and controlled in advance.
