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 close to a house can you plant a tree?

The recommended distance for planting a tree from a house depends on the tree's mature size and root system. As a general rule, plant trees at least:

• 10 feet away from foundations for small trees (mature height under 30 feet).
• 20 feet away from foundations for medium-sized trees (mature height 30-70 feet).
• 30 feet or more away from foundations for large trees (mature height over 70 feet).

Planting too close can lead to root damage to foundations, sidewalks, or underground utilities. It's always a good idea to research the mature size and root system of the specific tree species you're considering and consult with a certified arborist for guidance on proper placement.

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.
