I don't do spraying and injections, but provide on-site inspection of trees and plant material including visible soil conditions and surroundings. Every yard is treated as if it were my own, deciding what should be done or not done.

It's amazing how much is available to learn about trees. I forgot a fair number of tree minutia, but strongly retained aspects that pertained to the most common problems encountered over four decades, plus the most common benefits proven to succeed.

Don't panic. Hardly anything spreads overnight. It's remarkable how many things people notice sometimes that is actually normal or a healthy sign, thinking it's a tree disease, crisis or death knell. On the flip side, sometimes if trees look too good, maybe they're getting too much water and nutrients causing an imbalance between top weight and roots.

Basic arborist reports (sign-offs) are also available for people applying for removal permits. Some folks already work with other Certified Arborists in the valley. But I have gladly networked with responsible insured tree services that are not certified and don't qualify to sign for municiple requirements.

Certified Arborists are certified by the International Society of Arboriculture. Arborist training is also provided by universities and colleges, but Certified Arborists are tested and certified by the ISA with requirements for CEUs.

I was an arborist since 1980 and by 1985 far exceeded the education needed to pass an ISA arborist exam. In 2003 I decided to take the ISA test just to add the ISA Certified Arborist credential since more people are familiar with it, and maintained that certification from 2003 to present day.
