1. Temperature: the temperature suitable for cultivation of Rhododendron is 12-25 ℃, the maximum temperature shall not exceed 30 ℃, and the minimum temperature shall not be lower than 5 ℃; too high or too low will make Rhododendron stop growing. When the indoor temperature is high in summer, you can put it in a cool place. When the room temperature is low in winter, you should increase the indoor temperature properly.
2. Watering: the time interval between watering Rhododendron in different periods is also different. Generally, during flowering, you should water it every night; in spring or autumn, you can water it every 4-5 days.
3. Soil: Rhododendron is a kind of acid loving plant, so when preparing the soil, you can simply test it. If the soil you are preparing is slightly alkaline, you must replace it with acid soil.
If the Rhododendron is raised outdoors, we must pay attention to the insect damage, especially in spring. At this time, we can spray some medicine properly to prevent it. In winter, we should pay attention to keeping warm and cutting off the dead.
