Black tea is one of the most popular natural drinks in the world. The raw materials for its manufacture are tea bush leaves. It is grown in regions with a tropical and subtropical climate.
China is considered the birthplace of black tea, but today this plant is cultivated on plantations at the foot of the mountains in India, Africa, Georgia and even the Krasnodar Territory.
Externally, the tea bush is a dense plantation with high straight branches on which tea leaves grow. By nature, he is a long-liver. Some tea bushes survive several generations of pickers.
Tea bush can grow on dry stony soils, slightly covered with a layer of earth. It tolerates almost all weather conditions – from tropical heat to frost -20. An important condition for profitable plant cultivation is increased air humidity and abundant moisture in the earth in the form of natural rainfall.
