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.

Pruning a tree is a yearly DIY job that involves removing small dead branches, leaves, and blooms to help the tree grow bigger and stronger. You can often complete the job with basic home gardening tools. Trimming a tree, however, removes larger sections to control the direction the tree grows in and protects your home, utility wires, and yard from potentially dangerous branches.

A few signs a tree may be dead is if the leaves are dead and there are no signs of new blooms. You can also perform a scratch test on some of the branches to check the condition of the cambium layer beneath the bark.

If it is green, it is still alive, but if several are dry, brittle, and brown, the tree may be dying or dead. Always consult an arborist before assuming your tree is dead because you may be able to save it.

Getting a tree pro with the right experience can be the difference between your transplanted tree surviving or not. When hiring a local tree transplanting and removal service, follow up on references, check their portfolio, ask for a breakdown of the costs, and get proof of liability and workers’ compensation insurance. 

Also, look for companies certified by the International Society of Arboriculture or registered with the Tree Care Industry Association and make sure they have an appropriate state or city license.
