Merry Christmas and happy holidays!
It's hard to believe that we've come to the end of another year. Where did 2025 go? In fact, where have the past 2 decades gone as 2025 was the 21st year since I founded Arbor Doctor.
As I write this we are attempting to wrap up our early winter dormant oil applications, fall tree planting, and air knife services as conditions permit. One of the coldest and snowiest early winter periods on record has certainly hampered those efforts but we will have plenty of opportunity to finish these. Some of this will continue into the winter as conditions allow.
At the beginning of 2026, as we do every year, we will be mailing out letters detailing what services you are scheduled for in 2026. This will include an option to prepay for services. This is an option that some people like to take advantage of but it is not a requirement. If you wish to make any changes or additions in your service schedule, you must notify us. We do not automatically cancel out service schedules at the end of a calendar year.
Also during the winter we will be doing site visits where we visit some of your properties, inventory plants, and conduct field training with our team members. This is a free service where we can take a closer look at your plants and learn as a team in preparation for the coming 2025 season. If there are specific things that you would like us to give attention to during this winter period, please let us know.
It was yet another very busy year for us here at Arbor Doctor. We welcomed a number of new clients to our established and growing client base. There is never an end to the variety of new and varied plant health care challenges. New pathogens are always showing up and weather is always changing and varied. We had some very hot and dry summer periods, as well as some wet periods. We had more September drought but that was more short lived since October rainfall was normal and November rainfall was above normal.
One of the highlights of my year was the opportunity to attend the international conference of the International Society of Arboriculture in Christchurch, New Zealand in October. You can read more about that adventure at the following links:

At this time of the year, as Christians come together to celebrate the birth of Jesus, I'm reminded that I am truly blessed to be doing something as a profession that I love and have a passion for and to be providing a service of stewardship to you, my client.
Thank you for blessing me with the opportunity to care for your trees and your landscapes and I wish you a blessed holiday season and New year.
As always, feel free to call our Director of Operations Camille Rechel at 513-661-2673 with any questions.
