1, light temperature: the suitable temperature of camellia is between 18-25 degrees, and it is better to plant in spring in the north of the Yangtze River and in autumn in the south of the Yangtze River. Sandy loam with good drainage, strong water retention and rich humus should be selected for ground planting.

2. Water and fertilizer: Camellia requires high water content, and neutral and alkaline loam is not conducive to its growth. In the north, special attention should be paid to acidifying alkaline water before watering flowers. Camellia likes fertilizer. Generally, when putting or changing pots, apply sufficient base fertilizer at the bottom of pots.

3, plastic pruning: mainly to cut off dead branches, weak branches, cross branches, too dense branches and other branches that obviously affect the tree, as well as sparse and redundant buds.

4, winter maintenance: winter should pay attention to keep warm and shelter from the wind, but don't put it in places where the light is too strong or the temperature is too high, and at the same time reduce watering, especially not water, otherwise the roots will rot.
