Deciduous Trees In Your Outdoor Yard
Deciduous trees go through a process called abscission, in which the trees molt unneeded parts, usually the leaves. Most deciduous trees loose all their leaves annually before the tree becomes dormant in the fall/winter or during dry seasons in subtropical and tropical areas. Shedding its leaves helps a deciduous tree to conserve water for dormancy. The difference between evergreen and deciduous trees is that deciduous trees drop their leaves and go dormant, a process called abscission. Most gardeners believe this process occurs only in colder climates, when in fact, it can also occur in warmer climates during a dry season. Semi-deciduous trees lose old foliage only as new growth begins to develop, while other types of deciduous trees drop their leaves in the fall, go dormant and develop new growth in the spring.
A number of deciduous trees extract nitrogen and sometimes carbon from the leaves before they drop, storing it as proteins within root cells and the tissue lining the inner bark. In the spring, these proteins are converted to nitrogen during new growth to give a boost to foliage and flowers. According to North Carolina State University, most deciduous shade trees in a natural setting need little care, but when grown where their roots are restricted by pavement or compacted soil or where they are damaged by construction, this cycle can be disrupted. In this case, light fertilization in the spring will give your trees a boost.
