Frequently Asked Questions About Tree Services

How deep do tree roots grow?

The depth of tree roots varies depending on factors such as:

• Tree species: Some trees have deep taproots, while others have more shallow, spreading root systems.
• Soil type: Roots tend to grow deeper in loose, well-drained soil and shallower in compacted or rocky soil.
• Water availability: Roots will grow deeper in search of moisture in dry conditions.

In general, most tree roots are found within the top 3 feet of soil. However, some trees can have roots that extend much deeper, especially in favorable conditions. For example, oak trees can have taproots that go down 10 feet or more.

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.

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.

Do tree roots grow towards water?

While tree roots do grow towards moisture, it's not a simple case of them actively seeking out water sources. Roots grow in all directions, but they grow more rapidly and extensively in areas where they encounter favorable conditions, including moisture.
Roots have specialized cells called 'root hairs' that absorb water and nutrients from the soil. These root hairs are more abundant in moist soil, so roots naturally extend more in those areas. However, roots also need oxygen to survive, so they will not grow into waterlogged soil. The direction of root growth is influenced by a combination of factors, including moisture, oxygen availability, soil nutrients, and the tree's overall health.
