Why tea cannot be planted in plains?

Tea cannot be effectively planted in plains primarily due to the need for specific climatic and soil conditions. Tea plants thrive in well-drained, acidic soils typically found in hilly or mountainous regions, where the elevation helps maintain optimal temperatures and humidity levels. Additionally, the risk of frost and excessive heat in lowland areas can adversely affect tea growth and quality. Therefore, the topography and climate of plains are generally unsuitable for successful tea cultivation.
