1、 Soil

Black heart chrysanthemum can basically adapt to all soil types, but in order to grow better, it is recommended to use fertile and loose sandy loam for maintenance. In this way, the air permeability and drainage are very good. It is best to apply an appropriate amount of base fertilizer before planting to ensure nutrients

2、 Watering

During breeding management, watering should be dry and wet. There is much water needed in peak growth season, and the amount of water should be increased appropriately. Let the soil be moist during the bud pregnancy period. Reduce it after flowering. It's best to control the water

3、 Fertilization

More nutrients are needed during the growth period. Fertilizer should be supplemented and nitrogen, phosphorus and potassium compound fertilizer should be selected. Stop applying nitrogen fertilizer before flowering. At this time, apply more phosphorus and potassium fertilizer to promote flowering. There is no need to fertilize in winter because it almost stops growing

4、 Temperature

It is OK to provide a temperature between 10 ℃ and 30 ℃ during normal maintenance, which can prolong the flowering time. The high temperature in summer should be placed in a cool place and watered more to cool down. Put it indoors in winter to avoid frostbite

5、 Illumination

It likes light. It's best to provide it with enough light time during maintenance. It can receive full light in spring, autumn and winter. However, in summer, it should be shaded and placed in a semi shady place without strong sunlight
