How to plant a tree
Trees are a valuable part of any landscape. They provide shade, wind protection and visual appeal. They also reduce energy costs and serve as recreation for children and habitat for wildlife. Given the value of trees, it is wise to put consideration into their selection, planting and maintenance. Regardless of its background, any tree suffers a certain amount of "transplanting stress" during the period between planting and establishment. It may take several years after planting for a tree to regenerate a balanced root system. Once established, most trees require very little care. However, site preparation, planting technique and post-planting maintenance will all influence the establishment rate. When planting a tree, the main objective is to place a plant that is capable of growing roots rapidly into soil providing a good root growth environment. Many factors influence a tree's ability to grow roots.
