Spring cuckoo likes acid soil and grows poorly in calcareous soil. Therefore, most of spring cuckoos are cultivated in acid soil. Loose, rich in humus, good drainage, avoid clay or alkaline soil. Generally, several kinds of soil are used for configuration.
Spring cuckoos like a cool growth environment, semi - Yin conditions are better. It is not heat-resistant or cold resistant. The suitable temperature for growth is between 12 ℃ and 25 ℃. In summer, it is not heat-resistant. If the temperature exceeds 30 ℃, it will be semi dormant. It is not cold resistant in winter, and frostbite will occur when the temperature is below 0 ℃, so it is necessary to keep warm in winter. Like scattering light, not resistant to the sun exposure, summer needs appropriate shading, but we should pay attention to not over shading.
Spring cuckoo likes to be wet. During the growing period, the soil should be kept wet, not too dry or ponding. When the air is dry, you can spray water on the plants of cuckoo to increase the air humidity; when it is rainy, you need to drain water in time to prevent the soil from getting too wet and rotting.
The spring cuckoo should be fertilized with thin liquid fertilizer, which is used every half a month. Before blooming, it can be fertilized with one or two times of phosphate fertilizer to make the blooming big and gorgeous.
During the growing period, the Rhododendron usually grows naturally and seldom prunes. But after the spring cuckoo blooms, it needs to be renovated to cut off the long, weak, deformed and damaged branches.
There are fewer diseases and insect pests in spring cuckoo, but in the growth period, we should prevent the occurrence of diseases and insect pests, spray some disinfectants by air, and in summer, it is easy to outbreak red spider, so we need to spray.
The reproduction of cuckoo is mainly sowing, cutting, layering and branch propagation.
