It is possible to cut down a tree on your property yourself, but it is generally not recommended unless specific conditions are met. You should only consider this project if the tree is small (e.g., under 4-5 inches in diameter and short enough that you don't need a ladder to reach the branches), and you are experienced in handling a chainsaw. The tree must also be located far from any power lines, fences, homes, or other structures. Even for small trees, the work can be dangerous, and it's always advisable to have a spotter to ensure the tree falls correctly and no branches fall on you.

For any tree that is large, requires a ladder to access, or is near electrical lines or structures, you should always hire a professional. Attempting to remove a large tree yourself is extremely dangerous, poses a risk of serious injury, and could result in significant damage to your property.

Before any tree removal, it's also important to check your local and state regulations to ensure the tree is not historic or otherwise protected by your city.

Dutch elm disease can’t harm humans. In fact, according to Cal Fire, bark beetles aren’t even typically dangerous to trees unless that tree is already weakened. The problem comes when Dutch elm disease kills a tree. That tree is more at risk of falling and catching fire, which can pose a serious threat.

A chainsaw is the best tool to cut down a tree, but you may also use a handsaw or ax. You may also want to use a lopper or pole saw to remove limbs before cutting down the tree. Wear chainsaw chaps and protective gear, including eyewear and earplugs if you use a chainsaw. Again, if you’re unsure about how to use this tool, this project may be one to skip.

Tree trimming can count as landscaping, depending on how a landscaping business describes its services. Professional tree trimmers are more specialized than landscapers and offer trimming services separately from general landscaping.

When general landscaping companies offer tree trimming, look up the details. They usually mean shaping or seasonal trimming of ornamental trees, which is different from trimming larger trees for health or safety reasons. When possible, look for a licensed expert that specializes in trees and tree health.
