​Why do I need an Arborist?

Arborists are specialists in tree care. We are trained and equipped to evaluate a tree’s needs and provide it with everything it requires to grow and flourish. Proper tree care is the difference between attractive trees that add value to your property and a poorly maintained tree that is a danger and liability. Additionally, dealing with large trees can be dangerous work, both in terms of falls from high in the tree when pruning or removing branches, and falling branches that can damage property or cause injuries. Arborists are trained to take all the proper precautions, and can minimize the risks. Please feel free to browse our services and see how we can help you.

How Often Do My Trees Need to be Pruned?

Tree pruning requirements can vary widely depending on factors, such as:

  • Tree species, size of trees and how close they are to buildings, utility lines, etc.
  • Shading & decline issues causing deadwood
  • Storm frequency

Mature trees should generally be inspected annually for safety and health. Pruning frequency will generally range from 1 to 3 years.

Should I Remove My Tree?

There are many reasons to remove a tree, including hazardous condition, disease, thinning stand due to overcrowding, improper location or species choice, construction, etc. Herford’s Tree Care, Inc. has ISA Certified Arborists, who can evaluate your trees and help with this decision.

Why Is It Important to Prune Trees?

Clearance pruning from buildings and utility lines can prevent costly damage to these structures. Crown cleaning removes hazardous dead, broken and weak limbs. Crown restoration and structural pruning will aid the tree in maturing into a stronger and better looking specimen. Pruning also helps reduce disease and decline in many trees.

How Can I Tell If My Tree is Safe?

In most cases, a brief evaluation by our Arborists can easily decide if tree removal or preservation is the best course of action. In some situations, a thorough hazard tree evaluation may be required to make the determination. Techniques used during a hazard tree evaluation may include truck core sampling, root crown evaluation for signs of decay/disease, and other health evaluation and diagnostic methods.

Do I Need a Permit to Remove a Tree?

Most cities and towns in the Portland Metro area have tree removal permitting requirements, which are usually based on tree species, trunk diameter, property location, etc. You should always check with your City’s Planning or Urban Forestry Department to determine any permit requirements that may be applicable to your property. In some cases, Herford’s Tree Care, Inc. Experts can help you with this process.
