What is the best way to protect trees during construction?

Protecting trees during construction projects is crucial for preserving their health and preventing damage. Here are some key steps to take:

• Tree Protection Zone (TPZ): Establish a designated area around the trees that is off-limits to construction activities. The size of the TPZ depends on the tree's size and species, but generally, it should extend to the drip line (the outermost edge of the tree's canopy).
• Root Protection: Avoid digging, trenching, or compacting the soil within the TPZ. If excavation is necessary, use hand digging or air spading to minimize root disturbance.
• Trunk Protection: Protect tree trunks from damage by wrapping them with protective barriers, such as burlap or plywood.
• Branch Protection: Avoid cutting or damaging branches unless absolutely necessary. If pruning is required, have it done by a certified arborist.
• Watering: Ensure trees receive adequate water during construction, especially if the soil has been disturbed or compacted.
• Monitoring: Regularly monitor trees for signs of stress or damage during and after construction.

Consulting with a certified arborist during the planning stages of a construction project can help ensure the protection of valuable trees on the site. They can provide expert advice on establishing TPZs, minimizing root disturbance, and mitigating potential impacts on tree health.

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.

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.
