Tree trimming and tree pruning is the process of cutting and removing dead branches. Tree rimming usually refers to shrubs and tree pruning usually refers to trees. Tree pruning is performed in order to protect the tree or shrub while trimming is performed to ensure perfect growth of the shrub or hedge. Tree trimming service on the other hand is done to remove overgrown bushes which prevents the shrub from receiving enough moisture and light. Tree pruning service involves removal or dead or loose or infected branches so that the shrub can flourish properly. It is also done to give a particular shape to the shrub for aesthetic purposes.
rees are generally trimmed for one of three purposes: aesthetics, safety or health. For example: Aesthetics – Pruning a tree effectively helps to maintain its shape and appearance. However, you shouldn’t try to impose an unnatural shape or size on a tree. The amount of trimming and pruning that will be needed could seriously damage it. Safety – Dead or broken branches and limbs can fall off at any time, which is a serious safety hazard. If the branches of a tree obstruct your vision while driving, they should be trimmed away. Finally, tree limbs and branches occasionally grow too close to utility lines. Contact the utility company to handle such issues. Health – It is sometimes possible to save an infected tree by strategically pruning away affected branches and limbs. Thinning the crown of a tree improves airflow, which can be very beneficial. If branches are crossing or rubbing together, they should be trimmed so that they don’t fall unexpectedly.
This depends to a large extent on why you prune. Light pruning and the removal of dead wood can be done anytime. Otherwise, here are some guidelines, but recognizing that individual species may differ is important to remember. Winter Pruning: Pruning during dormancy is the most common practice. It results in a vigorous burst of new growth in the spring and should be used if that is the desired effect. It is usually best to wait until the coldest part of winter has passed. Some species, such as maple, walnuts and birches, may “bleed”—when the sap begins to flow. This is not harmful and will cease when the tree leafs out. Summer Pruning: To direct the growth by slowing the branches you don’t want; or to slow “dwarf” the development of a tree or branch, pruning should be done soon after seasonal growth is complete. The reason for the slowing effect is that you reduce the total leaf surface, thereby reducing the amount of food manufactured and sent to the roots. Another reason to prune in the summer is for corrective purposes. Defective limbs can be seen more easily, or limbs that hang down too far under the weight of the leaves. Pruning Flowering Trees to Enhance FloweringIf your purpose for pruning is to enhance flowering: For trees that bloom in spring, prune when their flowers fade. Trees and shrubs that flower in mid- to late summer should be pruned in winter or early spring. When Not To Prune: Fall: Because decay fungi spread their spores profusely in the fall and healing of wounds seems to be slower on fall on cuts, this is a good time to leave your pruning tools in storage.
