Question 1

Do I need a permit to take down my tree?

Accepted Answer

•

In some states and municipalities, you will need a permit to remove a tree on your property. In many cases where permits are required, a tree must reach a maximum height before a permit is required to remove it. You can either ask your local building department or a tree removal professional if you’ll need a permit. If you do, you can expect to pay between $50 and $150 for the permit alone. Your tree removal company should pull the permit for you and include the permit fee in your total.

Question 2

What’s the difference between a certified and consulting arborist?

Accepted Answer

•

There are two types of arborists: certified and consulting. A certified arborist is licensed and equipped to provide tree pruning, planting, fertilizing, monitoring, transplanting, treatment, and removal services. A consulting arborist specializes in tree appraisals, diagnosing problems and recommending treatments for illnesses. However, they will not provide these services themselves. Most consulting arborists are certified arborists who can refer you to a tree service that can administer the correct treatments.

Question 3

How damaged can a tree be before it’s considered a loss?

Accepted Answer

•

Most experts recommend removing a tree that has sustained more than 25% loss in the limbs, trunk, or circumference of the bark. Doing an initial trimming of damaged and dangling branches, but then waiting a few days of monitoring to decide how much more you might need to cut can help you better assess the total damage to the tree. However, consulting a tree maintenance pro to make this determination the best course of action before removing a tree.

Question 4

Should I use a pruning seal for trees after trimming?

Accepted Answer

•

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.

Question 5

How do you protect tree roots during excavation?

Accepted Answer

•

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.
