3. Continuation of life
Tea is a perennial deep-rooted crop which can live for several decades. Unlike other short-lived crops that require replanting, tea plants develop new buds after each plucking to provide new yield. At the end of every harvest season, the plucking areas of the plants are pruned to keep them neat and maintain the height at a controlled level. After repeated plucking and pruning, the size of new leaves will be reduced and quality deteriorates.
