Question 1

When should I remove a tree?

Accepted Answer

A tree should be removed if it is dead, dying, or poses an unacceptable risk to people or property. Signs include severe trunk decay, significant leaning, large dead branches, root damage, or proximity to foundations and power lines. An ISA Certified Arborist should perform a risk assessment before removal.

Question 2

How often should trees be trimmed?

Accepted Answer

Most mature trees benefit from pruning every 3 to 5 years. Younger trees may need structural pruning every 1 to 2 years to establish good form. Fruit trees require annual pruning. The specific frequency depends on the species, age, and health of the tree.

Question 3

What are signs of a dangerous tree?

Accepted Answer

Warning signs include: sudden leaning, cracks in the trunk or major limbs, hollow cavities, dead wood (branches without leaves), mushrooms growing at the base (indicating root rot), peeling bark, and heaving soil near the trunk.

Question 4

Can a dead tree fall?

Accepted Answer

Yes. Dead trees lose their structural integrity as the wood decays. They become brittle and are highly susceptible to falling during high winds, heavy snow, or even on a calm day. Dead trees should be removed promptly to avoid property damage or injury.

Question 5

What is stump grinding?

Accepted Answer

Stump grinding is the process of using a specialized machine to chip away a tree stump until it is well below ground level. This prevents the stump from resprouting, removes tripping hazards, deters pests like termites, and allows you to replant or grow grass over the area.

Question 6

When should I call an arborist?

Accepted Answer

Call an arborist if you notice yellowing leaves out of season, dead branches, signs of insect infestation, fungus on the trunk, or if you need pruning near structures. You should also consult an arborist before construction projects to protect roots, or for a general health assessment.

Question 7

Why hire an ISA Certified Arborist?

Accepted Answer

ISA Certification ensures the individual has achieved a level of knowledge in the art and science of tree care through experience and passing a comprehensive exam. Certified Arborists understand tree biology, proper pruning techniques, and safety protocols, ensuring your trees are cared for correctly rather than simply "hacked" apart.
