Frequently Asked Questions About Tree Services

Why do tree roots grow above ground?

Tree roots growing above ground, also known as surface roots, can be caused by:

• Shallow Soil: In areas with thin or compacted soil, roots may not be able to penetrate deeply and instead grow near the surface.
• Soil Compaction: Heavy foot traffic, construction activities, or vehicles can compact the soil, making it difficult for roots to grow downward.
• Low Oxygen Levels: Roots need oxygen to survive, and in poorly drained or compacted soil, they may grow near the surface to access more oxygen.
• Seeking Nutrients: Roots may grow towards areas with higher nutrient concentrations, which can be near the surface in some cases.
• Tree Species: Some tree species are naturally prone to surface roots, such as maples, willows, and poplars.
• Age: As trees age, their root systems expand, and some roots may naturally grow closer to the surface.

Surface roots can pose tripping hazards, damage sidewalks or driveways, and interfere with mowing. Addressing underlying issues like soil compaction or drainage can help prevent excessive surface root growth.

Is it OK to cut tree roots?

Cutting tree roots can be necessary in some situations, but it should always be done with caution and preferably under the guidance of a certified arborist.
**When it's OK to cut roots:**

• Small roots: Cutting small, superficial roots during landscaping or gardening is usually not a significant problem for the tree.
• Encroaching roots: Roots growing into sidewalks, driveways, or foundations may need to be cut back. However, it's essential to do this carefully to avoid damaging the tree's structural integrity.
• Root pruning for transplanting: Before transplanting a tree, root pruning is done to encourage new root growth within a smaller area, making the transplanting process more successful.

**Risks of cutting tree roots:**

• Tree instability: Cutting large structural roots can weaken the tree's support system, making it more susceptible to windthrow or breakage.
• Disease entry: Cuts create wounds that can serve as entry points for disease-causing organisms.
• Reduced nutrient and water uptake: Cutting roots can limit the tree's ability to absorb water and nutrients from the soil.

Before cutting any significant tree roots, consult with a certified arborist to assess the situation, determine the best course of action, and minimize the risk of damage to the tree.

What is the best time of year to trim trees?

The best time to trim trees depends on the tree species and the type of trimming needed. Here are some general guidelines:

• Dormant Season (Late Fall to Early Spring): This is generally the best time to trim most deciduous trees (those that lose their leaves in fall) as they are not actively growing. Trimming during dormancy reduces stress on the tree and allows for better wound closure.
• Spring: Light pruning and shaping can be done in spring before the tree's leaves fully emerge.
• Summer: Trimming can be done in summer to remove dead or diseased branches. However, avoid heavy pruning during hot weather, as it can stress the tree.
• Fall: Some light pruning can be done in fall after the leaves have fallen, but it's best to avoid major pruning before winter.

Specific tree species may have different optimal trimming times, so it's always best to consult with a certified arborist for guidance. They can assess your trees and recommend the best time to trim them for optimal health and safety.

What are the different types of tree services offered?

Tree service companies offer a wide range of services to meet your tree care needs, including:

• Tree Removal: Complete removal of trees, often necessary for diseased, damaged, or hazardous trees.
• Tree Trimming & Pruning: Selective removal of branches to improve tree structure, health, and aesthetics. This includes crown lifting, crown thinning, and crown reduction.
• Stump Removal/Grinding: Removal of tree stumps using specialized grinding equipment, leaving the area level with the ground.
• Tree Planting: Selecting and planting new trees on your property, considering factors like soil type, climate, and available space.
• Tree Cabling & Bracing: Installing support systems for weak or structurally compromised branches to prevent breakage.
• Tree Health Care: Services focused on maintaining or improving the health of your trees, including fertilization, disease diagnosis and treatment, and pest control.
• Emergency Tree Service: Urgent tree care services for situations like storm damage, fallen trees, or hazardous tree removal.

The specific services offered may vary depending on the company's expertise and equipment.
