1、 Illumination

Immortal refers to a person who likes sunshine very much and needs to be exposed to sunshine all year round. Otherwise, the branches and stems will become smaller, the number of flowers will become less, the flowering period will be shortened, and the ornamental value will be greatly reduced. Put it on the balcony for maintenance. Only when sufficient light is ensured can photosynthesis be carried out normally, synthetic nutrients promote the plant to be strong and powerful, and the flowers bloom smoothly. However, the sun is very strong in summer, and appropriate shading is needed to avoid the atrophy and yellowing of the stem segment

2、 Watering

It can endure drought and has little demand for water. However, in order to ensure good growth, it is necessary to maintain sufficient water in the spring and autumn growth season. It is not allowed to water too much. It is enough to replenish water appropriately to keep it moist, otherwise it will lead to plant rotten roots and flowers wither and fall off. When it is in dormancy, it should pay attention to control watering

3、 Fertilization

It doesn't like to apply excessive fertilizer, but it needs nutrient support for growth and flowering, so it needs to apply fertilizer every 10-15 days. Before flower bud differentiation, phosphate fertilizer should be applied every 7-10 days. It will enter dormancy in winter and semi dormancy in summer. At this time, the growth is slow and fertilization needs to be stopped

4、 Temperature

It likes to be warm. The appropriate temperature is kept at about 15-25 ℃. It can't stand the cold. It should be kept above 10 ℃ in winter
