Generally speaking, you’ll want to avoid flush cuts, which are cuts made as extremely close to the trunk or main branch. These cuts can weaken your tree, lower its natural defense mechanisms, and even cause decay. You’ll also want to avoid tree topping, which is the total removal of the leader and upper main branches of a tree. 

Most pros will advise against either of these methods, which is why hiring a pro is often the best choice when it comes to tree trimming.

Your neighbor is not in a good position to know if your trees are truly dead or pose any kind of danger. That’s why hiring an arborist or tree service expert can be such an important part of the process. If the trees are still alive and don’t pose any threat, you’re in the clear (but you may want to document and photograph everything in case events turn sour down the road).

But if a tree is visibly dead and near the property line, you should remove it to be safe. If a dead tree falls on a neighbor’s property, they may have grounds to sue for negligence. If any branches on trees have died, it’s a good idea to cut them back for similar reasons.

Sometimes, knowing when you need tree-trimming services is straightforward, and other times, you have to do some investigating. Some tell-tale signs that you should have your tree trimmed include:

• A poorly-formed tree with unruly branches, which makes the tree appear odd-shaped. 

• A tree with tall or large branches that interfere with power lines or your home’s exterior.

• A tree that provides too much shade in the yard due to branch overgrowth.

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.
