Frequently Asked Questions About Tree Services

Why is my tree dripping sap?

Sap dripping from a tree can be caused by several factors:

• Insect Infestation: Some insects, like aphids, scales, or borers, feed on tree sap, causing it to drip or ooze from wounds or feeding sites.
• Disease: Certain diseases, like bacterial wetwood or slime flux, can cause sap to flow excessively from cracks or wounds in the bark.
• Mechanical Injury: Wounds or cuts in the bark, caused by pruning, storms, or other physical damage, can lead to sap dripping.
• Environmental Stress: Extreme heat, drought, or other environmental stresses can sometimes cause trees to produce excess sap.

If you notice sap dripping from your tree, it's important to identify the cause to determine the appropriate course of action. A certified arborist can help diagnose the problem and recommend treatment or management options.

What are the most common tree problems?

Trees can be affected by a variety of problems:

• Diseases: Fungal, bacterial, or viral infections that can weaken trees, cause defoliation, or lead to death.
• Pests: Insects or other animals that can damage leaves, branches, bark, or roots, weakening the tree and making it more susceptible to disease.
• Environmental Stress: Drought, extreme temperatures, poor soil conditions, or pollution can stress trees, making them more vulnerable to pests and disease.
• Mechanical Damage: Wounds caused by construction, lawnmowers, or vehicles can create entry points for pests and disease.
• Structural Defects: Weak branches, cracks, or cavities in the trunk can weaken the tree's structure and make it prone to breakage.
• Improper Pruning: Incorrect pruning techniques can damage trees, create wounds, and make them more susceptible to disease.

Regular inspections by a qualified arborist can help identify and address tree problems early, preventing further damage and maintaining tree health.

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.

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.
