Welcome to Arbor Doctor! 

Serving Cincinnati, Southwest Ohio, Northern Kentucky, and Southeast Indiana.


Arbor Doctor LLC is based in Cincinnati, Ohio, and serves clients in Greater Cincinnati and the Northern Kentucky suburbs. We offer a full range of plant health care and landscape services including organic, deep root fertilization, seasonal foliar nutrient applications, tree preserva-tion, diagnostics, and consulting. 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.
