The Importance of Hiring a Certified Arborist in New Zealand

What is an Arborist?

An arborist is a professional who specializes in the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants. Arborists are knowledgeable about the needs of trees and are trained and equipped to provide proper care to keep trees healthy and safe.

There are several reasons why New Zealand homeowners and property owners should consider hiring a certified arborist. Arborists can help with a variety of tree care needs, including planting, pruning, pest and disease management, hazard evaluation, and more. They have the skills, knowledge, and equipment to do the job properly. When health and safety is a priority, it's important to trust tree care to qualified professionals like certified arborists.

Unlike gardeners or landscapers, arborists are experts specifically trained in tree biology, identification, and management. Arborists know how to foster tree vigor and recognize signs of decline or danger before problems get worse. They can provide specialized care that promotes growth and longevity for maximum property enhancement and environmental benefits. With their expertise, arborists are an important resource for keeping trees in New Zealand thriving for generations to come.

Tree Health

Maintaining tree health is a key focus for arborists. They can help prolong the life and condition of your trees in several ways:

  • Pruning - Strategic pruning removes dead, diseased, or problematic branches. This improves tree structure, allows more light penetration, and promotes new growth. Arborists know where and how much to prune without harming the tree.
  • Fertilization - Applying the right fertilizers at the right time of year provides trees with important nutrients. Arborists test soil and analyze tree needs to determine optimal fertilization.
  • Cabling - Cabling is used to provide supplemental support for weak or heavy branches. Arborists properly install cabling and braces to improve structural integrity without damaging the tree.
  • Pest and Disease Management - Early detection and proper treatment of pests and diseases helps safeguard tree health. Arborists recognize symptoms, identify causes, and recommend effective organic or chemical controls.
  • Aeration - Aeration involves puncturing the soil underneath trees to allow air, water and nutrients to better penetrate the roots. Arborists determine when aeration is needed.
  • Mulching - Applying an organic mulch layer moderates soil temperature and moisture while suppressing weeds. Arborists advise on proper mulching depth and materials.
  • Watering - Arborists help establish proper watering schedules and techniques for optimal tree hydration. Too much or too little water can stress trees.

With their extensive knowledge and specialized techniques, certified arborists are well equipped to maintain and monitor the health of your trees over time. Their skills and expertise lead to healthier, safer, longer-lasting trees.

Pest and Disease Identification

Arborists and tree care specialists are trained to recognize signs and symptoms of pests, diseases, fungi, and other pathogens that can harm trees. Some of the most common problems they look for in New Zealand include:

  • Kauri Dieback - This soil-borne disease affects kauri trees and can be identified by symptoms like yellowing or thinning canopy, dead branches, lesions on the trunk, and gum bleeding from the bark. An arborist knows how to spot the early signs and can recommend treatment options.
  • Borer Insects - Borers are beetle larva that bore into tree trunks and branches. Evidence includes sawdust-like frass, holes in the bark, canopy dieback, and dead branches. Proper identification allows for timely pest control.
  • Canker Diseases - Fungal diseases like cytospora canker cause sunken, dead areas of bark on branches and trunks. The margins spread outward year after year, eventually girdling and killing the branch. Arborists recognize these signs.
  • Wood Decay Fungi - Decay fungi attack the heartwood of trees, causing rot inside the trunk or major branches, making the tree unstable and hazardous. An arborist can spot outward signs of fungal fruiting structures, holes, cracks, or even a hollow trunk.

By identifying pests, diseases, and fungi early, the arborist can recommend appropriate treatments to maintain tree health and prevent further damage or spreading to other trees. Their expertise is essential for detecting threats before they become fatal to the tree.

Hazard Assessment

A certified arborist can assess the health of your trees and identify any potential hazards. Over time, trees can develop structural weaknesses from decay, disease, pests, or damage that can make branches prone to failure. One major role of an arborist is evaluating trees on your property for risks like:

  • Dead, dying, or broken branches
  • Cracks, cavities, or weak branch unions
  • Previous damage from storm events
  • Leaning or unstable trunks

If an arborist detects any high risk defects, they can recommend options to reduce the hazard such as pruning, bracing, cabling, or removal if the risk is too great. Having hazardous branches preemptively mitigated protects your property from damage and prevents injuries. Large, decaying branches can fall and crush cars, homes, or injure people below. A certified arborist has the knowledge to systematically inspect trees and rate the severity of defects they find. Their hazard rating helps prioritize which trees need immediate attention. With routine assessments, hazardous trees can be identified and treated before branches fail.

Tree Removals

Removing trees, especially large trees, can be extremely dangerous if not done properly. Tree removal is a technical process that requires expertise to be done safely and effectively.

Certified arborists are trained in proper tree removal techniques to preserve the surrounding landscape and prevent property damage or injury. They have the skills to determine if a tree can be removed in sections or if the entire tree needs to be brought down at once.

Arborists use techniques like directional felling to control how and where a tree falls. They also know how to properly rig and lower large tree sections to the ground in a safe manner. This prevents damage that can be caused by tree sections freely falling and impacting the area.

Proper tree removal protects nearby structures, gardens, vehicles, and importantly, people. As trees being removed can have massive trunks, branches, and root systems, arborists take care to dismantle and remove them in a logical order.

Overall, arborists have the expertise to safely and efficiently remove trees of any size. Their technical knowledge and rigging skills are essential for the complicated process of taking down large, mature trees in residential and commercial areas. Hiring a certified arborist for tree removal protects people, property, and the surrounding landscape.

Tree Selection

Choosing the right tree for the right place in your yard or property is crucial. There are many factors to consider like the size of the tree, how fast it will grow, how far apart it should be spaced from structures and other trees, and more. An arborist has specialized knowledge about tree species, their characteristics and requirements to thrive. They will evaluate your landscape conditions and recommend appropriate trees that are suited to the soil, sunlight, moisture levels, and hardiness zone.

For example, some fast-growing trees like poplars can cause problems as their invasive roots spread and branches get too heavy. An arborist can suggest better alternatives. Some trees need acidic soil or are prone to disease and pests, which the arborist will know about. They can advise you against planting trees near foundations, septic systems, sidewalks, power lines or close together where overcrowding causes competition. With their expertise, arborists ensure you select the right trees that will enhance your property, avoid future issues, and have the best chance of growing healthy and strong.

Planting

A certified arborist knows how to properly plant and establish new trees for optimal health and longevity. They understand how to prepare the planting site, including assessing the soil conditions and drainage. Arborists will amend the soil if needed to encourage good root growth.

When selecting the tree, an arborist considers the site conditions like sunlight, wind exposure, and available space to choose an appropriate species. They know which types of trees are suitable for the climate and environment. Arborists are also knowledgeable about proper handling and care of the tree when transporting it to avoid damage.

Planting techniques used by arborists support tree stability and growth. This includes digging an adequately sized planting hole, proper backfilling methods, and staking if necessary. Pruning damaged branches or roots is also important for tree health. Arborists are trained on appropriate initial pruning when planting.

Ongoing care and maintenance after planting can determine the success or failure of a newly planted tree. Arborists provide advice on watering needs, fertilization, and protection during establishment. Hiring an arborist for planting new trees greatly improves their chances of thriving for years to come.

Tree Protection

Trees located on construction sites require special care and protection to ensure they survive the construction process. Construction activities like excavation, grading, and compaction can damage tree roots and compact soil, which cuts off air and water to the roots. Construction equipment and materials can also hit and scrape tree trunks and branches.

A certified arborist knows how to protect trees properly before and during construction. They will first assess the health of trees and determine which ones are priority for preservation. Then they will fence off root zones so equipment cannot run over roots. Arborists may install mulch layers over root zones to prevent soil compaction. For trees very close to the construction area, they may prune branches or install trunk protection to prevent damage.

The most critical protection is the tree root system. An arborist will identify the root zone that needs protection. In some cases, they may suggest tunneling utilities under roots rather than trenching through roots. Arborists can also recommend temporary irrigation or aeration if the tree has reduced water or air from construction activity. Proper tree protection with an arborist consultant can make the difference between preserving or losing valuable trees on a construction site.

Cost Savings

Hiring a certified arborist in New Zealand can lead to significant cost savings for homeowners and property managers. Arborists are trained to spot issues with trees early, before they become expensive problems.

For example, an arborist can identify weak branches that may break off and damage property during a storm. By pruning those branches preemptively, the arborist prevents property damage that could cost thousands of dollars to fix. An arborist may also diagnose diseases or insect infestations affecting tree health. Treating those issues promptly can save the tree, rather than facing costly removal and replacement later on.

In some cases, the arborist may determine that a declining tree needs to be removed. Though tree removal is an expense in itself, it is far less costly than waiting for the dying tree to uproot and destroy landscaping or strike your home. The arborist can remove the tree in a controlled manner to prevent collateral damage.

Beyond disease and structural issues, arborists can also suggest preventative care to support tree health. This may involve fertilization, cabling, lightning protection, or soil amendments. A little bit of preventative care goes a long way to avoid large issues down the road.

Overall, hiring a certified arborist is an excellent investment. For a reasonable fee, arborists provide expertise to maintain healthy trees and prevent expensive problems from developing on your property. Their knowledge and advice can save thousands in property damage, removal, and replacement costs over the lifetime of your trees.

Safety

 

Working with trees, especially large trees, can be extremely dangerous without proper training and equipment. Arborists are experts in safety when it comes to tree care and maintenance.

Arborists are trained to safely prune, cable, and brace trees. They know how to properly operate cranes, aerial lifts, rigging equipment, and other specialized machinery needed for tree care. Arborists understand how to assess risk factors and take precautions to protect themselves, the tree, property, and the public when performing tree work.

Certified arborists are also trained in proper use of personal protective equipment (PPE) like hardhats, eye protection, hearing protection, chainsaw chaps, and climbing gear. They follow industry safety standards and best practices to minimize injury. With arborists, safety comes first on every job.

Homeowners attempting tree work on their own without arborist training are at a much higher risk of injury from falling branches, electrocution from nearby power lines, and improper use of equipment. Hiring a certified arborist ensures maximum safety. Their specialized skills, knowledge and equipment allow arborists to handle hazardous trees and perform complex procedures beyond the ability of regular homeowners.

When it comes to the inherent dangers of working with tall trees, it's always best to call in the professionals. Arborists make safety their top priority.

Local Knowledge

Arborists have extensive knowledge of the trees that grow well in your local environment. They understand the climate, weather patterns, soil conditions, water drainage, and other factors that impact tree health in your region. This allows them to properly select, plant, and care for trees suited to the unique conditions of your property.

For example, an arborist in Auckland will be familiar with native New Zealand trees like kauri, pōhutukawa, and tōtara. They know which introduced species also thrive in the Auckland area, like maple, oak, and magnolia. This expertise helps ensure the right trees are planted in the right places for maximum success.

In addition to tree species knowledge, certified arborists know about local pests and diseases. Familiarity with common threats in your area allows them to properly diagnose issues and recommend effective treatments. They can identify and manage invaders like myrtle rust, giant willow aphid, or blue-stain fungus based on extensive local experience.

By leveraging in-depth understanding of local tree species, growth conditions, and threats, certified arborists in your region can provide specialized care tailored to your property and trees. Their expertise which trees will do well in your yard, keep them healthy, and address any problems that arise.
