The cost of professional tree service, such as trimming, is $460 on average, but the price can range from $75 to $1,800. A more typical range is between $200 and $760. The final price depends on several factors, including the size and type of the tree. For example, trimming Crepe Myrtle trees costs an average of $80 to $400, while giant pine trees can range from $200 to $1,800. Other factors that influence the cost include the time of year, as services are often more expensive in the spring. Your location can also play a role; costs may be higher if you live in a remote area or if the tree is difficult to access. However, some professionals may offer a discount if you have multiple trees that need service.

The ideal time to prune a tree depends on the type of tree. Typically, late winter or early spring is a good time to prune but isn't always the case for "towering trees." It's best to trim when trees are dormant and before blooms appear but can vary depending on the tree type. It's always best to research the type of tree or ask a professional tree trimmer to determine when is the perfect time to prune your tree.

There are a few instances in which removing a tree is the best option. You might do this if the tree looks to be a major danger—potentially falling onto your home, your car, or other parts of your property—or it’s diseased beyond repair. A tree that is growing too close to your house might need to be removed to prevent mold growth.

Generally, you’ll want to prune back the trunk by 1 to 2 feet each year to promote bushy growth. Doing so concentrates vegetative buds closer to the bottom of the tree, where you can easily harvest fruit. For side shoots that are a year old, leave at least six leaves. 

Never remove more than 30% of a tree’s foliage during pruning—even if your tree is really overgrown. Removing this much foliage at a time could kill your tree.
