Birch Tree Lifespan
How old do birch trees get? The answer to this question depends in part on the species of the tree. It also depends on its growing conditions. Paper birch trees (Betula papyrafera), also known as white birch or silver birch, are popular garden trees. The species is native to this continent. The lifespan of a paper birch in the wild is between 80 and 140 years. Cultivated paper birches have a much shorter life if they are grown in the home landscape. Here they may only live between 30 and 40 years. Some species of birch can live hundreds of years under optimal conditions. For example, the yellow birch (Betula alleghaniensis) can live for up to 300 years, although its average lifespan is 150 years in the wild. The sweet birch (Betula lenta) can live to be 250 years. Birch tree lifespans decrease when the trees are planted in a backyard for a variety of reasons. First, cultivated birch trees often get inadequate irrigation, insufficient sun, and, given those stress factors, they suffer from diseases and pest damage. This can reduce the lifespan of a birch in your backyard to less than 20 years.
Extending the Lifespan of a Birch
Once you know how different the lifespan is for cultivated birch trees, you may feel inspired to give yours excellent cultural care. If you want the lifespan of a birch in your backyard to be long and happy, give the tree the same conditions it would have in the wild. In a forest, birches grow in cool, moist soils. You need to plant your birch trees where the soil will be shaded, cool, and moist. On the other hand, birch trees require sunshine on their leaves to grow well. For a maximum birch tree lifespan, find a site where the tree’s roots are in cool soil but its leaves are in the sun for a good part of the day.
