Advantages: the aroma is much more obvious. It is also because of the unique smell.
Disadvantages: the flowering period is too short, and it only blooms once a year in May and June. Cultivars can bloom many times a year. In addition, after cutting, it will wither quickly within 30 minutes, which is very unfavorable for preservation.
There are about 2000 species of camellia, which can be divided into 3 categories, including 12 flower types. In 2065,438+03, there were more than 306 species of camellia in China.
Growing habits:
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.
