Eight key points of culturing cuckoo
Rhododendron has luxuriant branches and colorful flowers, so we must pay attention to the following eight points in cultivation and management: first, the mud pot is the most suitable for the selected flower Shen rhododendron pot, especially the seedlings, because the mud basin absorbs water and breathes air, which is beneficial to the growth and development of roots. Purple sand basin can also be used for more than 3-year-old seedlings, but more broken tiles and coarse-grained soil should be padded at the bottom of the basin to facilitate ventilation and drainage, otherwise the roots are easy to rot. Second, the pot soil rhododendron likes to be loose, fertile, good drainage, pH value between 5.5,6.5 slightly acidic mud or culture soil. If more calcareous alkaline soil is used or drainage is not available.

Scientific management of rhododendron
Cuckoos like scattered light and cool and humid climate, afraid of hot sun exposure. Therefore, appropriate conditions such as light, temperature and humidity should be adjusted and managed scientifically. At the same time, special attention should be paid to the acidification of soil and water quality. After entering autumn, when the night temperature is below 10 degrees Celsius, move it indoors and place it in the sunny place. After the beginning of winter, move it to a lower temperature shade, do not need light, make it hibernating. At this time, the suitable temperature is about four degrees, and there is no need to water the soil if it is not dry. In early spring and February, move to a place with scattered light at room temperature of about 9 degrees.
