This is probably the most frequently-asked-question we get.

To answer it, all we can say is this: Different species of trees look different at different times of the year and at different stages of their growth. It takes a trained and experienced pair of eyes to see what's unusual or "not quite right" about a particular species of tree. That's why when you call for a tree inspection, you should rely on an arborist who has the experience, knowledge, and qualifications to do a thorough and accurate assessment.
