Red Alder Trees
Red alder trees are common landscaping trees which can grow up to 100 feet in height. They are fast-growing tree species especially for those areas where there are seriously damaged by forest fire or other disasters. Their seeds are able to feed a number of wild animals and birds and provide shelter for them as well.
They prefer to grow in well-drained soil conditions with adequate sunlight. However, they can tolerate a number soil types such as clay soil or loam soil. They can also in infertile areas where the nutrients in soil are poor. One of the most astonishing features is that they can convert the nitrogen from the air into the nutrients in the soil. This feature enables them to provide adequate nitrogen for their own use as well as the nearby plants.
Red alder trees prefer moist environment to grow well. They can resist extreme drought conditions and they won’t get damaged in some minor floods. They need adequate precipitation especially in winter and autumn. They like full sunlight for their growth and cannot tolerate partial shade environment. They are mostly growing in open areas where are just cleared by some natural hazards such as forest fires etc. Unlike most trees, they cannot live for a long time and most of them can just live for 50 to 70 years.
