Arborists use this information, combined with their knowledge of tree biology, to develop a treatment plan or recommend specific actions to improve tree health. Their goal is to prevent further damage and keep the tree strong and sustainable.
7. Common Tree Problems and How Arborists Handle Them
Trees can face many challenges throughout their lifespan, ranging from environmental stress to diseases and pests. Arborists are experts in identifying these issues and implementing the appropriate solutions.
Disease Management
One of the primary concerns for arborists is tree diseases, which can spread quickly and lead to the decline or death of trees. Common tree diseases include:
- Dutch Elm Disease: A fungal infection that attacks elm trees, causing wilting and eventual tree death. Arborists can manage this through early detection, pruning infected branches, and using fungicides.
- Oak Wilt: This fungal disease affects oak trees, particularly red oaks. It is spread by beetles and can quickly destroy a tree. Arborists can limit the spread by pruning infected branches, preventing root grafts, and using specific fungicides.
- Powdery Mildew: This fungal infection causes a white, powdery coating on leaves, stunting the tree’s growth. Arborists can control mildew by recommending fungicide treatments and proper pruning to improve airflow.
Arborists are equipped with the tools and knowledge to diagnose these issues and treat trees effectively. They may apply the necessary treatments or recommend changes in care to restore tree health.
Pest Control
Insects like aphids, borers, and caterpillars are common pests that damage trees. They can weaken trees by feeding on leaves or by burrowing into trunks and roots. Arborists use a variety of methods to deal with these pests, such as:
- Insecticidal Sprays: Arborists may apply insecticides to control pests. They ensure the correct chemical is used for the specific pest, while minimizing damage to the environment.
- Biological Control: This involves introducing natural predators of pests, like ladybugs, which help reduce the pest population without harmful chemicals.
- Traps: Arborists may use physical traps to capture pests and prevent them from spreading.
By controlling pests, arborists help prevent further damage to trees and protect other plants in the area.
Soil and Root Problems
Tree health is directly tied to the quality of the soil and the condition of the roots. Arborists assess soil health and may recommend soil treatments to enhance nutrient availability. Common soil issues include compacted soil, poor drainage, or low nutrient levels. Arborists may address these by aerating the soil, improving drainage, or adding mulch to improve root health. Root issues, such as damage from construction, can be serious. Arborists can take measures like root pruning or rerouting to mitigate damage to the tree’s root system.

Pruning and trimming trees isn’t as simple as just cutting away dead branches. Arborists use specific techniques to promote healthy growth and prevent damage to trees. Understanding these methods is key to keeping trees safe and thriving.
Proper Timing
The timing of pruning is essential for a tree’s health. Arborists typically recommend pruning during the tree’s dormant season, in late winter or early spring, when trees are not actively growing. This minimizes the stress on the tree and allows it to heal faster. Some trees, however, may require pruning during their growing season, depending on the species and specific needs.
Thinning
Thinning involves removing selected branches to allow more light and air to reach the center of the tree. This technique helps improve the tree’s overall structure and promotes healthier growth. By thinning the canopy, arborists help reduce the risk of disease and pest infestations.
Crown Raising
Crown raising is the process of removing lower branches to provide clearance for people, vehicles, or buildings. This technique is often used for trees in urban areas where branches may interfere with sidewalks, streets, or infrastructure.
Crown Reduction
Crown reduction involves reducing the size of a tree’s canopy to maintain its shape and reduce wind resistance. This technique is often used for mature trees that have become too large or have outgrown their space. By carefully reducing the canopy, arborists can help trees stay healthy and less susceptible to damage in storms.
Deadwood Removal
Deadwood removal is essential for maintaining tree health and safety. Dead or decaying branches can pose a risk to people and property. Arborists remove these branches promptly to prevent them from falling and causing damage. Removing deadwood also allows the tree to redirect its energy toward healthier growth.
