How to raise camellia? What should I pay attention to?

When the temperature reaches above 30 degrees in summer, camellia should be kept indoors for maintenance. Camellia likes acidic soil, so it is necessary to adjust the PH value of the soil before summer, and adjusting it to acidity is beneficial to the growth of camellia.

Camellia belongs to loose and fertile sandy loam, loess or humus, with Gao Shuang topography, good ventilation, warmth and humidity, and good drainage. pH5 .5-6。 5 is the best. The optimum temperature is between 20-32℃. When the temperature is above 29℃, the growth will stop, and when the temperature is 35℃, the leaves will be anxious, which requires a certain temperature difference. The environmental humidity is above 70%, and most varieties can withstand the low temperature of -8℃ (naturally overwintering, but Yuncha is not cold-tolerant). Generally, it can naturally overwinter in acidic soil south of Huaihe River, which requires 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.
