Who doesn’t love a beautiful tree? Trees give us shade; some provide fruit in the summer and windbreaks in the winter. In the spring, some produce lovely flowers, and in the autumn, colorful leaves. Like every pretty thing, though, trees require maintenance. They need to be trimmed and pruned when their branches hang low, and someone has to clean up after they have shed their flowers, leaves and seed pods. There are two main kinds of trees: deciduous and evergreen.
