Why Leaves Change Color in Arden, NC
Every fall in Arden, NC we observe the gorgeous nature of different trees. Red, orange, yellow, and even purple leaves develop directly from the massive changes in our tree’s biology. Throughout the hot months of the year, leaves are utilized for the almost sole purpose of providing nutrients to our trees. Through photosynthesis leaves are kept green with chemical processes using chlorophyll. However, during the early autumn changes in climate, weather, temperature, and access to sunlight all have an impact on the tree. Thus, the leaves decide to stop making food for the tree. At this point the leaves are no longer producing chlorophyll and instead begin to change into the fall colors we know and love. Trees such as dogwoods or sumacs will often create purple colored leaves during this time. Oak trees will often produce brown leaves as a result of leftover chlorophyll.
Interestingly, the reason leaves fall from your tree at this point is due to a unique process that occurs on the branches, limbs, and twigs. The process begins to release the leaves from the tree, and the tree begins to cover the wounds. Colder temperatures will often help to create red leaves during the fall. Precipitation helps to inspire more extreme color changes throughout the fall.
