1. Soil: Rhododendron camellia is suitable to grow in loose and fertile acid soil. Can use saprophytic soil, garden soil and river sand to carry on the preparation, want to choose flowerpot with better permeability at the same time..
2. Light: the growth of Rhododendron Camellia can not be separated from sufficient light. Every day to ensure a long time of sunshine, but summer needs to be shaded, not be exposed to strong light, or it will cause the leaves to turn yellow and dry.
3. Watering: camellia and Rhododendron prefer humid environment. When the surface of the soil is dry and the inside is still wet, you can water it. Do not wait until it is completely dry. The amount of water should not be too large, so as not to flood the roots.
