Tea trees are kept small by tea growers and are evergreen throughout the seasons. In their natural state, they can grow to be up to 30ft tall. However, tea growers keep their tea tress to within 4-5ft in height. This ensures that the tea trunk remains thick and encourages more leaf and branch growth. Tea growers do so to get as much leaves as possible from their trees as the leaves are the sole product of tea trees. Keeping the tea trees short makes tea harvest easier to harvest.
