Welcome to Arbor Doctor LLC! 

Our team will provide you with landscape and tree care solutions in Greater Cincinnati, Southwest Ohio, Northern Kentucky, and Southeast Indiana.

Unlike pesticide-centric plant health care programs, our organic nutrients are healthy for your plants. The nutrients thicken the cell walls to help the plants defend against insect attacks and be as resistant as possible to disease. Pesticides may still be utilized, but only in a targeted, limited fashion. We use pesticides which are low or no toxicity whenever possible.

Ron, I just wanted to say thank you for the the job you did in “re-woodsing” the hill in our backyard. As you can see, the fall colors are spectacular. The Parotia, in particular, is showing yellow, gold and red. And the Spring Grove dogwood is the most brilliant red, and perfectly placed. Just think of what it’ll look like in a few years when the trees start getting larger! We really appreciate your help. Thanks.

Connie & Karl, Westwood

Very professional.

Homeowner in Hamilton, OH.

Great job today, Ron!  Everyone really liked listening to you (speak to our garden club).
