The optimum temperature for the growth of camellia is between 20℃ and 25℃. When the temperature is above 29℃, it will stop growing, and the leaves will be anxious at 35℃, which requires a certain temperature difference. The environmental humidity is above 60%, and most varieties can tolerate the low temperature of -8℃ (naturally overwintering, but Yuncha is not cold-resistant), and generally can overwinter naturally in the south of Huaihe River. I like acidic soil and need good air permeability.
In order to promote the growth of root hairs, peat, sawdust, red soil, humus soil or a mixture of the above substrates can usually be used for culture. Camellia can not shade in spring, autumn and winter, but can shade 50% in summer. Camellia has a long flowering period, generally starting from June 10 and ending in May of the following year, and reaching its full flowering period from June/kloc-0 to March.
