Tea is grown in different states of Myanmar. The total tea plantation area is around 70,000 hectares with an annual production of 78 million Kg green leaves. The best quality and major cultivation are in Northern Shan State. More than half of the total output is from Namhsan area, a mountainous region with deep slope that forms a natural drainage system, vital for tea plantation. The soil type is red acid with PH value of 4.5-6.0. The altitude ranges from 1200 m to 1800 m above sea level, and has an annual rainfall of 1000 mm to 1600 mm.
