What Arborists Really Do

Nov 19, 2025

Arborists are trained professionals in the science of trees and other plants. Their work focuses on maintaining plant health and improving structure. They protect landscapes from pests, diseases, and environmental stress. At My Arborist, our team is trained with ISA-certified professionals to diagnose issues and create care programs. Our services include maintenance scheduling for trees, insect control, and more. Here’s the range of services arborists perform:

Root Fertilization and Soil Health

Arborists offer tree and shrub fertilizing for modified soils or environments. Some landscape or urban trees require more nutrients for growth and development. Professionals can improve the root structure, allowing the tree to have better blooms, natural immunity, and longevity. At My Arborist, our team specializes in diagnosing and developing custom care programs for trees and shrubs. 

Before applying custom treatments, tree doctors evaluate soil composition. This assessment determines the correct blend of fertilizers for specific tree species. The process enhances oil aeration and microbial activity. It leads to enhanced nutrients and overall growth. 

Tree and Shrub Insect Management

Insect activity can weaken trees and shrubs, so arborists are trained to recognize signs of insect infestations, including defoliation, leaf distortion, premature leaf drop, and boreholes in bark. Early detection is key as several insects, such as emerald ash borers and scale insects, spread rapidly. Once the problem is identified, professionals develop care treatment plans; these include applying insecticidal sprays, tree injections, or horticultural oils. This also helps avoid disruption of beneficial organisms. Integrated pest management practices can reduce the need for harsh chemicals by combining biological control methods. Regular monitoring helps keep infestations under control before they impact the health of the trees.

Tree and Shrub Disease Treatment

Trees and shrubs are susceptible to a range of diseases caused by fungi, bacteria, or environmental stressors. Professionals apply diagnostic techniques to determine the type and extent of infection. Tree diseases can include oak wilt, apple scab, and needle cast, which spreads through root systems. To improve drainage and airflow, professionals apply fungicides, prune infected branches, or alter site conditions; these interventions limit the spread of pathogens and support the recovery process.

Preventive disease management includes monitoring seasonal conditions and maintaining proper watering schedules. This also includes pruning to reduce moisture accumulation. By identifying disease risks early, professionals help protect individual trees and the surrounding landscape. At My Arborist, our team addresses various diseases, including anthracnose. 

Tree Injections and Growth Regulation

Tree injections deliver nutrients, insecticides, or fungicides directly into a tree’s vascular system; this technique allows the materials to circulate internally, minimizing environmental exposure. An arborist applies the treatment, avoiding damage to vital tissues. Growth regulation is also applied to slow canopy expansion. It allows the tree to direct more energy toward root development and structural integrity.

Use Arborists For Tree Health 

Arborists combine biology, soil science, and environmental management to sustain healthy landscapes. Their role involves diagnosing complex issues, applying treatments, and implementing long-term care strategies. At My Arborist, our team offers services such as deep root fertilization. We help improve both the health and longevity of trees. Contact our team today to learn more about our technical and environmental skills.
