1. Temperature: the temperature suitable for its development is between 18 ° C and 28 ° C, and the winter temperature can not be lower than 5 ° C, because of the characteristics of cold resistance, when the temperature is lower than the limit temperature, there will be black rot of branches and leaves. After flowering, keep the temperature at 16 ° C, so that the flowering period can be prolonged, and if the maintenance temperature is too high, the flowering period will be reduced.
2. Watering: its branches, leaves and flowers are relatively large, and it needs a lot of water. In the growth period, it needs to water in the morning and evening every day, and in winter, it needs to control water, just two or three times. When pouring, we need to control the amount. When pouring, the soil will be completely wet.
3. Fertilization: before planting, it is necessary to add base fertilizer to the soil, which consumes nutrients faster. During the growth period, it is necessary to apply fertilizer once every half a month. The fertilizer seed can choose the diluted fertilizer cake water. In order to prevent soil alkalization, when fertilizing, you can add 2% ferrous sulfate to the fertilizer, and before flowering, you can add potassium superphosphate solution to the water, which can help flowers to color and make them more colorful.
4. Light: it is not suitable for long-term maintenance in a sunny environment. It needs to be maintained in a relatively cool place in summer, so as to prevent the branches and leaves from being burned. After September, the light will slowly weaken. At this time, it can be moved to a place with more light for breeding.
1. Reproduction: in April and may, choose the top tender spike of Hydrangea as the cuttings, insert it into the prepared fine sand bed, water it with enough water, put it in the dark environment with the temperature of about 25 degrees, and it will grow in about 20 days.
1. Insect pest: the diseases it infects mainly include powdery mildew and leaf spot disease. After discovering such diseases, 65% of zineb wettable powder will be mixed with water and sprayed for treatment..
1. Whether it can be planted at home: its flowers are easy to cause allergy to people with sensitive constitution. If someone at home is sensitive to pollen, it is not recommended to breed. If there is no allergy person, it can be bred.
