Accepted Answer

Tea bush is a tropical and sub-tropical plant and thrives well in hot and humid climate. There is a very close relationbetween climate, the yield and the quality of tea. The ideal temperature for its growth is 20&#176;-30&#176;C and temperatures above 35&#176;C andbelow 10&#176;C are harmful for the bush.&#61623; Temperature: 21&#176;C to 29&#176;C is ideal for the production of tea. High temperature is required in summer. The lowest temperature forthe growth of tea is 16&#176;C.&#61623; Rainfall: 150-250 cm of rainfall is required for tea cultivation.&#61623; Soil: Tea shrubs require fertile mountain soil mixed with lime and iron. The soil should be rich in humus.&#61623; Land: Tea cultivation needs well drained land. Stagnation of water is not good for tea plants. Heavy rainfall but no stagnancy of water, such mountain slopes are good for tea cultivation.
