Pruning an overgrown pear tree can seem like a daunting task, but with a little patience and the right tools, it can be easily accomplished. The first step is to remove any dead or diseased branches. Their dry, brittle appearance can identify these. Next, cut back any branches that are rubbing against each other or crossing over each other. This will help to promote air circulation and prevent the spread of disease. Finally, prune any branches growing inwards towards the tree's centre. This will encourage the tree to grow outward, creating a more balanced shape. With a little effort, an overgrown pear tree can be transformed into a healthy and beautiful specimen.
