Before you start pruning any tree or shrub, it is important to sterilize the saw and nail clippers to prevent the spread of any disease to a healthy tree. Professional tree trimming services that invest heavily in marketing, such as ads on Google, Yelp, Yellow Pages, and signs in the city, will generally be more expensive than those that don't. Pruning a tree located in your backyard will cost more due to the difficulty of dragging branches to the front of your property. In some parts of California, a heritage tree is defined as any tree with a trunk circumference of 55 inches or more, or that measures at least 35 feet in height.
Other municipalities may have different definitions for heritage trees. Removing or pruning a heritage tree requires a permit in most cases. The cost of removing trees and stumps will depend on the size of the tree and its location. If it is a young tree with small branches that can be easily cut while standing on the ground, DIY is an option.
However, without taking proper precautions and having the right equipment in place, pruning a tree can quickly become dangerous or even deadly. For deciduous trees that lose their leaves, pruning before the tree starts to shed can help give an idea of its shape. To make your yard look as attractive as possible, you may need to periodically have your trees cut into shape. A 20-foot tall tree with a pest problem right next to your neighbor's garage requires more effort (and money) to prune than a healthy 20-foot tree in the middle of an open field.
