Rose City residents may not know the difference between landscapers and arborists. They might just think of it as working with “Thorns” versus “Timbers.” However, the comparison is more complex than that and goes far beyond Providence Park!

Horticulture and arboriculture share some common ground – the care of natural surroundings. Landscapers and arborists can work together, yet the two are not interchangeable. While both work with plants, one is more specialized than the other. When looking for Portland tree services, it’s important to know the difference between landscapers and arborists, or else you could end up with lackluster service.

You can expect Landscapers to know how to care for the land, such as:

Designing and installing landscape (natural features) or hardscape (man-made fixtures).
Installing and maintaining lawn irrigation, and ensuring proper water drainage.
Covering land with mulch to enrich or insulate the soil.
Preparing, creating, and maintaining garden beds.
Pruning shrubs to promote health.

Although landscapers are skilled at horticulture, they are ill equipped to handle complicated tree projects. Landscapers may not have the appropriate tools or training to complete arboricultural jobs correctly – or safely. Too often, a landscape contractor attempts arboriculture, only to hurt himself or damage the property.

In contrast, Arborists are “tree doctors” who specialize in tree health. They are extensively trained and properly equipped to tackle challenging tree work, such as:

Assessing the condition of trees and how to heal disease.
Pruning trees, in consideration of available space, tree health, and productivity.
Removing or reducing trees correctly and safely.
Cabling or bracing vulnerable branch unions to create structural support.
Transplanting and replanting trees to more appropriate locations.
Performing deep root or tree spike fertilization to provide trees with key nutrients.
Injecting fertilizers and pest control formulas into trees.
Grinding stumps, ensuring a tree’s remnants are is eradicated.

Safety considerations highlight the differences between landscapers and arborists. Arborists are trained to use specialized tools to climb and cut trees safely. From rigging to harnesses to aerial lift equipment, providing Portland tree services for the towering species in our area requires unique equipment—equipment that landscapers don’t have.

Liability insurance distinguishes these fields as well. Trustworthy Portland certified arborists carry extensive liability insurance to protect themselves and the homeowner; in contrast, landscapers are not typically insured for arboricultural liability. Homeowners may have to foot the bill for damage if the contractor doesn’t carry the proper insurance for Portland tree removal or other services.

City codes for the City of Portland State that homeowners must obtain permits before planting, pruning, or removing certain trees. According to the city’s new tree code, failing to acquire the correct permits could bring fees of up to $1,000 per day, per tree. To avoid fines, it’s best to work with a certified, experienced arborist. For example, Portland arborists can identify whether you have a heritage tree on your property. Heritage trees are protected by City Code; they can only be removed when officials confirm that they’re dead, dying, or dangerous—and in all cases, you’ll need Portland certified arborists to get the job done safely.

Ultimately, it’s best to see these two fields—Horticulture and Arboriculture—as separate jobs best left to their respective professionals, landscapers and arborists. Of course, some Portland arborists also offer extensive landscaping services. However, for the health of your trees and the safety of your family, it’s best to entrust tree services only to certified arborists.
