Paper birch seedlings are fragile and germinate most readily in shaded areas in soil that is high in minerals, but they grow taller more quickly in soil that is rich in organic matter, such as the humus that is found on the forest floor. Seedlings grown under these circumstances are about 4 1/2 inches tall at the end of the first growing season.
Paper birches experience most of their growth while they are young, with some trees' trunks measure 8 inches in diameter after 30 years. Growth rate falls off as the trees age, and in mature trees between 60 and 70 years old, is no longer noticeable.
Paper birch is a medium to fast grower, which means that it can experience between 13 to 25 feet of vertical growth per year or more. This growth rate depends on soil type, drainage, weather conditions and sun exposure.
