Characteristics of Evergreens.
There are a few benefits for trees that fall into the evergreen family that deciduous trees don’t enjoy. In areas that endure cold or dry seasons, there is usually a shortage of nutrients during those seasons, and being an evergreen can be an adaptation to that shortage. When deciduous trees are growing new leaves during the spring, they need a great deal of nutrients, but evergreen trees don’t require as much because they do not put out so much energy at one time, as they do not grow all of their leaves at one time. Because of this, they can often endure a rough season, when a deciduous tree might not be able to. Evergreens are also better equipped to survive harsh seasons because their leaves act as a kind of insulation, protecting the tree against frost damage. The dead leaves even help the tree after they are finished helping on the tree! Once shed, the still nutrient-rich foliage acts as natural mulch that protects the tree’s roots. This mulch helps stop other growth that could leech nutrients and moisture out of the soil, allowing the tree to utilize the available resources to the fullest potential.
Whether in cold, dry climates or in hot, humid rainforests, evergreens are certainly a wonder! And though evergreens don’t have the beauty of color changing leaves, in the middle of winter, the still-green tree has a beauty of its own, standing as a reminder of life persevering.
