Tea Production
　　
　　A new tea-plant must grow for five years before its leaves can be picked and, at 30 years of age, it will be too old to be productive. The trunk of the old plant must then be cut off to force new stems to grow out of the roots in the coming year. By repeated rehabilitation in this way, a plant may serve for about l00 years .
　　
　　For the fertilization of tea gardens, Soya-bean cakes or other varieties of organic manure are generally used, and seldom chemical fertilizers. When pests are discovered, the affected plants will be removed to prevent their spread, and also to avoid the use of pesticides.
　　
　　The season of tea-picking depends on local climate and varies from area to area. On the shores of West Lake in Hangzhou, where the famous green tea Longjing (Dragon Well) comes from, picking starts from the end of March and lasts through October, altogether 20-30 times from the same plants at intervals of seven to ten days. With a longer interval, the quality of the tea will deteriorate.
　　
　　A skilled woman picker can only gather 600 grams (a little over a pound) of green tea leaves in a day.
　　
　　The best Dragon Well tea is gathered several days before Qingming (the devil festival when new twigs have just begun to grow and carry "one leaf and a bud." To make one kilogram (2.2 lbs) of finished tea, 60, 000 tender leaves have to be plucked. In the old days Dragon Well tea of this grade was meant solely for the imperial household; it was, therefore, known as "tribute tea".
　　
　　For the processes of grinding, parching, rolling, shaping and drying other grades of tea various machines have been developed and built, turning out about 100 kilograms of finished tea an hour and relieving the workers from much of their drudgery.
　　
　　Organic tea
　　
　　In recent years, organic tea has caught on. By organic tea, it means that organic fertilizer is used to provide fertility to tea trees and no farm chemicals are used.
