What Is an Arborist and When Should You Hire One?

Trees are like gifts that keep on giving; bearing fruit, offering shade, and uplifting a property with their mere existence. 

But every property owner in Auckland knows how soon a tree can go from being an asset to a headache real quick especially if there’s a storm. 

While some trees need regular upkeep to keep them looking lush and healthy all year long, some require removal for any landscaping plans that homeowners may have.

If you’ve got a tree on your property that needs a little trimming or a full removal, an arborist is the right person to call. In this article, you’ll learn what an arborist does and how you can choose the right one to manage trees in your garden.

What is an Arborist?

An arborist is a trained individual who is skilled at cultivating, management for, and preservation of trees. An arborist’s speciality usually combines practical experience and knowledge in tree biology, structural integrity, soil conditions, pests, diseases, and safety protocols.

Unlike general gardeners or landscapers, arborists focus specifically on the long-term health and safety of trees.

The approach taken by an arborist is not always focused on getting rid of or cutting down the tree. The first thing that an arborist does is examine the tree, taking into account the species, the age of the tree, its pattern of growth, and other factors, to determine what should be done in order to maintain the tree’s health and safety.

More often than not, the solution will not include getting rid of the tree. It can be some type of pruning, or disease management, and even regular observation and prevention of any potential diseases.

What Does an Arborist Do?

Arborists provide a wide range of services that support tree health while keeping public safety in mind:

Tree Health 

Trees usually display some signs when they’re not healthy. These signs include changes in leaf colouration, reduced growth rate, branch dieback, or the presence of fungi around the trunk area. An arborist will recognize such symptoms, figure out what the problem is, and provide useful advice on how to solve it before the situation gets worse. 

Tree Pruning

Pruning doesn’t just mean the removal of extra growth. Tree pruning Auckland is a proper way to help trees form better structures, provide better airflow for them, trim off the dead and unhealthy parts, and minimize future risks of tree failures. At the same time, improper pruning could damage a tree, increase its susceptibility to diseases and structural issues in the future. 

Tree Risk Assessments

Regular tree assessments can identify internal decay, compromised root systems, storm damage, and structural weaknesses — helping you take the right action on time before the tree becomes an active hazard. A qualified arborist evaluates potential risks by assessing factors such as trunk condition, branch attachments, root stability, canopy balance, and overall structural integrity to help you make the right call.

Tree Removal

Sometimes, getting a tree removed is the best option, especially if it’s harder to manage, severely diseased, irreparably damaged by storms, or posing an obvious risk to nearby people or property. An experienced arborist can help you with safe tree removal Auckland so you can resume your life without disruption.

Arborist Reports and Professional Advice

Situations such as property developments, insurance claims, council applications, and disputes involving neighbouring trees require more than practical tree work. 

A certified arborist can assess your property and provide documented recommendations, so you can make the appropriate regulatory preparation.

When Should You Hire an Arborist?

Most homeowners hire arborists after the tree becomes an obvious problem. However, waiting too long can often worsen existing problems and leave them with lesser options.

Timing is essential in determining when to consult an arborist, because this way you will be able to avoid unnecessary risks and expensive emergencies.

Here are some telltale-signs that point to hiring an arborist:

  • Severe tree damage due to bad weather or high wind
  • Leaning or cracked structure
  • Overgrowing branches towards windows, driveways, or neighbouring properties
  • Symptoms of sickness or signs a tree is about to die i.e. dead branches, abnormal shedding, decaying.
  • Plans of construction in your property
  • You’re unsure whether a tree requires pruning or removal
  • If you are buying or selling a property which has large or mature trees

Why Hiring a Professional Arborist Is Worth It

Trees are an asset that can pay off for years to come. The maintenance of trees is important not only for aesthetic purposes but also in order to ensure protection and safety from any risks in the future.

The first reason to hire a certified arborist is the provision of preventive measures. Early detection of problems such as decay, disease or structure weak spots allows you to avoid more complex procedures in the future. At the same time, regular maintenance will help to prevent the failure of the branches and the damages it could cause to the house, cars, fences or the landscape around it.

Another reason for hiring a professional arborist is that every cut done to the tree impacts the way it develops in the future. Properly performed pruning promotes further development; however, incorrect pruning leads to permanent damage or reduced lifetime of the tree.

The final and probably the most important reason for using the services of a professional arborist is that all uncertainties disappear. In other words, you will not wonder whether you need to cut a tree or not.

How to Choose the Right Arborist

Not all arborists are the same. Many arborists have dedicated specialties, and they might be the right fit for certain jobs.

But the right way to find the ideal arborist is through their qualification. Certified arborists come equipped with experience and knowledge from the International Society of Arboriculture (ISA), which is a reassurance that your trees receive the safest and most effective care.

Apart from this, having significant experience in handling different trees and adequate public liability insurance is also crucial. The right arborist will choose appropriate procedures, use specialized tools, and walk you through their chosen approach.

Another important aspect to take care of is the pricing. It’s worth asking an arborist if they charge for first on-site inspection, have a straightforward pricing structure, and if any potential costs that may be added later. 

Lastly, digging into customer reviews will also help you distinguish between a good and a great arborist.
