In most cases, you should not use a pruning seal on trees after trimming. Applying a sealant can interfere with the tree's natural healing process, and it does not guarantee protection from pathogens. Instead of sealing the cut, the best practice is to support the tree's natural recovery by providing it with plenty of water and a dormant-style fertilizer. However, there are exceptions. Pruning seals may be recommended for very vulnerable species, like elm trees, in areas where dangerous diseases such as Dutch elm disease are prevalent. In these specific situations, the protection offered by a sealant can outweigh its downsides. For advice tailored to your situation, especially after cutting large branches, it is best to consult a local tree trimming professional.

Any tree that needs to be pruned should be pruned to remove dead branches at least once a year. You may need to prune far more often if you’re trying to maintain a certain shape or to save a tree that suddenly becomes infected.

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.

In the short term, you’ll have a lot of fallen trees to deal with. Tree removal services costs typically start at $200 per tree and increase based on species and size. Then, you’ll have to deal with the loss of trees: That means a loss of shade and a greater risk of rain runoff and erosion. Also, you’ll miss out on the health and aesthetic benefits of having trees on your property, which could even affect the resale value of your home.

That being said, cutting down a tree it’s not always a bad idea. Trees growing too close to rooftops can present fire hazards or debris problems. You may need to remove diseased or dying trees to prevent future issues.
