Pruning is an effective way to prevent a diseased branch from infecting the rest of the tree. If the infection isn’t caught early enough and the pathogen has spread to the trunk or the majority of the branches though, it is too late to prune off the affected areas and you’ll likely need to remove the tree.

Ideally, you’ll have a good enough relationship with your neighbors that you can kindly mention this task in regular conversation. However, every neighbor (and neighborhood) is different. Your best bet will always be to ask directly and nicely, offering to contribute to the tree trimming efforts if you’d like. However, if you are bothered by the tree and your neighbor is unwilling to cut it, you can involve the help of the homeowners’ association or local authorities, if applicable.

For trimming trees, your best tool is a pair of pruning shears or loppers. Both options work best for branches that are under 3 inches in diameter. Trimming trees with a larger diameter may require a robust tool like a small chainsaw or a handsaw, so take into account your tree’s diameter when deciding between tools.

Although the terms tree trimming and tree pruning are used interchangeably, they are very different types of tree maintenance. Tree trimming involves enhancing the appearance of your tree by removing unruly branches, providing your tree with ample sunlight and nutrients and prevents unsightly overgrowth. 

Tree pruning helps keep your trees disease-free. This process removes unhealthy growths, dead branches, and other unhealthy parts of the tree. It’s more common for deciduous and ornamental trees but not so common for evergreen trees. To determine which method you need, discuss it with a tree trimming specialist.
