Trees may need pruning to maintain a particular shape, remove diseased or dead branches or prevent them from touching power lines or rooftops. Pruning is also essential to promote fruit production and increase the value of timber. In fact, pruning is the most common tree care activity for landscape trees, but it should be done with caution. Improper pruning can damage a tree damage or even kill it. When done properly, however, pruning can promote healthy tree growth and prevent tree hazards, such as falling branches.
Photosynthesis is the process by which trees manufacture energy for growth and maintenance. This process occurs in foliage, so pruning should be done carefully. Overpruning may inhibit a tree's ability to perform photosynthesis, thus limiting its ability to create food and grow.
