If the treatment you were recommended is not listed above, that means there are multiple different treatment methods to choose from based on timing and pest vulnerability and will be done under best discretion of the arborist. Please contact Aaron Schulz for more information.

We do not do any Plant Health Care treatments from January and February, since that is dormant season and it will not be effective.

Let's help you assess your safety needs and put a plan into action.
