Frequently Asked Questions About Tree Services

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.

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.

How do I know if my tree is diseased?

Look for these signs of tree disease:

• Leaf discoloration or spots: Yellowing, browning, or spotting on leaves can indicate fungal infections, nutrient deficiencies, or other problems.
• Premature leaf drop: Losing leaves earlier than usual or outside of the normal seasonal cycle can be a sign of stress or disease.
• Dieback of branches: Branches dying from the tips inward can indicate disease, insect infestation, or drought stress.
• Cankers or lesions: Sunken or discolored areas on the bark can indicate fungal or bacterial infections.
• Mushrooms or conks growing on the trunk or roots: These are often signs of decay fungi.
• Wilting or drooping leaves: Can indicate a lack of water, root damage, or vascular disease.

If you notice any of these signs, it's best to contact a certified arborist for a professional diagnosis and treatment recommendations.

How much does tree service cost in USA?

• Type of service: Tree removal is typically more expensive than trimming or pruning.
• Size and location of the tree: Larger trees or those in difficult-to-access locations will cost more to remove.
