Serpentine chrysanthemum likes to have plenty of sunshine, and is a little shade resistant. In addition to the hot summer weather, other seasons can be placed in bright light outdoor maintenance. The balcony and windowsill of the house are very suitable positions. They are not only ventilated and have sufficient light, but also can choose the half shade position. The premise is that there should be enough 5 hours of light for Spiraea every day, and at the same time, dust should not fall on Spiraea.
The requirement of Spiraea on soil is not high, and it grows fast in sandy loam with medium fertility, looseness and good drainage. If the soil fertility is too strong, it will affect its growth.
Spiraea likes to be warm, not cold resistant and afraid of extreme heat. The optimum growth temperature is 15-25 ℃. If the growth limit is more than 30 ℃, it should be kept in a cool place. If it is more than 10 ℃, it can survive the winter safely.
Echinacea prefer to be slightly dry to slightly wet environment. It is drought resistant and afraid of being wet. Spring, summer and autumn are the main growing seasons. The lower temperature in spring and autumn can maintain a slightly dry environment. The temperature is higher from the end of spring to the beginning of autumn, and the evaporation is larger. More water can be poured to keep the basin soil slightly wet. In winter, the plants were dormant and kept a little dry. Water control and drainage in rainy days. Be careful not to get too wet, otherwise the disease will occur easily.
Spiraea is resistant to barren and does not like fertilizer. It is prone to lodging in places with high fertility. Spring and autumn are the main growth season. If there is enough organic fertilizer at the bottom of the pot before transplanting as the base fertilizer, it is not necessary to apply fertilizer in the growth season. After budding, it can apply phosphorus and potassium fertilizer. In summer, it is not necessary to apply fertilizer. In order to prevent lodging, potassium fertilizer can be increased appropriately. Do not apply fertilizer in summer and winter.
