Tree Fertilization & Soil Amendments

Most trees, particularly in urban areas, need regular fertilization to replenish essential nutrients lost through leaching and poor soil health. After inspecting your trees, our tree health experts apply a scientifically formulated mix of nutrients that are tailored to the current season as well as the needs of your tree.

Fertilization is carefully timed to ensure it’s done at the right time of the year to promote absorption and maximize effectiveness. We can also identify and treat nutrient deficiencies that can cause your trees to become weak and vulnerable to pests and diseases.

We use full spectrum, slow-release fertilizers that are low on the salt index for maximum effectiveness. Our fertilizers contain a combination of ingredients that are beneficial to tree health and growth, including micronutrients and mycorrhizae.

Soil Amendments for Optimal Tree Health

The foundation of healthy tree growth begins with the soil. Soil amendments are essential in promoting a thriving environment for trees, especially in the varied soil conditions found in the Portland area. Our soil amendment services are designed to enhance soil quality and ensure that your trees have the best possible conditions for growth.

Our first step is always a thorough evaluation of your existing soil condition. We take samples and analyze them to understand pH levels, compaction, organic matter content, and existing nutrient profiles. Based on the assessment results, we craft a customized amendment plan. Common amendments we use include:

  • Organic matter, such as compost, which improves moisture retention and nutrient availability.
  • Gypsum to break up compacted soils (this is particularly beneficial in urban settings where soil compaction is common).
  • Lime to adjust soil pH levels, which can be critical for nutrient uptake in the acidic soils prevalent in some Portland areas.

Our team applies soil amendments with precision and care, ensuring even distribution and minimal disturbance to existing root systems. We use tools and techniques that integrate amendments into the soil without harming the trees.

At ArborPro, we are committed to providing the highest quality soil amendment services to ensure that your trees and landscape are healthy, vibrant, and beautiful. Let us help you enhance the natural beauty and health of your Portland area property with professional soil care tailored to your unique environmental conditions.

Our approach is environmentally friendly and safe for humans and pets, while also being effective in eliminating tree pests and preventing diseases. We believe in using the least toxic methods possible, such as cultural controls, organic insecticides, and biological controls, before resorting to chemical treatments.

Root Zone Improvement for Healthy Root Growth

Root zone improvement involves various techniques aimed at enhancing the soil around a tree's roots to promote healthy root growth. By optimizing the root environment, trees experience the following benefits:

 

  • Enhanced Tree Health: Improved root health leads to healthier, more vigorous trees that are better able to resist diseases and pests.
  • Increased Drought Tolerance: Trees with healthy root systems are more efficient at water uptake and can better withstand periods of low rainfall, a common challenge in certain Portland areas.
  • Longevity and Stability: By encouraging deeper and more extensive root growth, our services help ensure that your trees are stable and can live longer, contributing to the overall canopy and ecosystem.

Our Root Zone Improvement Techniques 

  • Air Spading: One of the key tools in our root zone improvement arsenal is air spading. This technique uses compressed air to gently break up compacted soil around the tree’s roots without damaging the roots themselves. This aeration process improves soil drainage and oxygen availability, crucial for healthy root growth.
  • Vertical Mulching: We employ vertical mulching to mitigate soil compaction. By drilling small holes around the tree's root zone and backfilling them with organic material, we enhance water penetration and root respiration, promoting a healthier root system.
  • Radial Trenching: This technique involves creating trenches in a spoke-like pattern away from the tree’s base to encourage roots to grow outward. This not only helps in nutrient uptake but also stabilizes the tree by expanding its root system.

 

Maintaining the health of your trees starts below the ground. Let ArborPro help you manage and improve your trees' root zones with our expert services, designed to ensure your trees are a lasting, vibrant part of your property.

Expert Doug Fir Inspection and Care”

Arbor Pro just inspected and did work on a very big Doug Fir on our property. We'd been concerned about it's health. They went up to the top, inspected for dead wood, removed anything necessary and gave it a good bill of health. They even recommended wildlife habitat solutions and provided sites where we could find more information. On time, clean and professional.

Treat Your Trees Right with a Custom Fertilization & Soil Care Plan

Every tree is unique, as is the soil around it. Ensure optimal tree health and growth with a personalized soil care plan tailored to your tree’s specific needs and designed to remedy any deficiencies or problems in the surrounding soil.

Insect Pest & Disease Management

One of the most important services we offer is tree pest and disease control, which is essential for maintaining healthy trees and preventing damage. Portland is home to a variety of common tree pests, such as aphids, spider mites, bark beetles, and scale insects, as well as a range of destructive diseases, all of which can weaken and even kill trees if left untreated.

Integrated Pest Management (IPM)

This eco-friendly approach to tree pest and disease control involves -

  • Careful inspection to identify pests or diseases that are harmful to your trees and the extent of the infestation.
  • Development of a targeted treatment plan that minimizes the use of chemical pesticides and mitigates any damage.
  • Strategic application of insecticides to affected areas, ensuring minimal impact on the surrounding ecosystem
  • Regular monitoring of your trees post-treatment to ensure pests do not return.

Offering Both Prevention & Control of Tree Bugs & Diseases

We offer both preventive and corrective treatments for a wide range of tree problems. The choice of treatment types will depend on the pest or disease affecting your trees, time of year, severity of the infestation or infection, and more.

  • Trunk Injections – Treatments are injected directly into the tree to prevent spraying non-target trees and nearby structures and ensure maximum uptake of treatments.
  • Soil Drenching – This method directs treatments to the tree roots where they can be quickly absorbed and spread throughout the tree.
    • Tree Spraying – As a last resort, we may apply specialized sprays, in the safest and most efficient way possible, to help protect your trees and prevent the spread of diseases such as Dutch elm disease, oak wilt, and cedar rust.

We also offer ongoing pest management plans to prevent future infestations.

Organic, Natural & Highly Effective Treatments

We also offer organic and natural treatments when possible. These treatments are effective and environmentally friendly, and they minimize the use of chemical pesticides. Our treatments are customized to the specific needs of your trees and are designed to protect them from further damage.

“Reliable Tree Maintenance Since 2015

We have been working with Arbor Pro to maintain our trees since 2015. They have done trimming, tree care treatments and sometimes tree removals.

I highly recommend their company and look forward to working with them in the future.

Tree Cabling, Bracing & Structural Support

Cabling is used to support structurally weak or damaged trees. We install high-quality cables to stabilize branches, helping to redistribute weight, reduce the risk of branch failure, and prevent further damage during high winds or storms.

During a thorough tree inspection, our arborist will determine if cabling is necessary to support the tree’s structure and enhance stability. If so, we’ll install the necessary cables, ensuring that all cabling is done according to the latest safety standards to protect both your property and your trees.
Our team will also Inspect cables periodically and adjust them as needed to ensure the tree's safety and health.

Quality Materials and Equipment: 

We assess each tree to determine what support system is most appropriate. We then use the best choice of materials and system available, whether that is a static system made with steel or a dynamic system with synthetic materials, or a combination of both.
