Our Specialty

Tree DoctoRx has been providing cutting-edge horticultural services for over 15 years. We specialize in tree and landscape health care. Services such as consulting, diagnosis, hazard evaluation, appraisal, fertilization, nuisance fruit control, and insect and disease treatment are overseen by Four Certified Arborists. In addition, we provide various other horticulture services such as pre-emergent and post-emergent weed control, exotic species control, and aquatic weed control.

Tree DoctoRx believes in using Integrated Pest Management (IPM), low-toxicity, and organic-based products with our services. Integrated Pest Management (IPM) is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM programs use current, comprehensive
information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.

To learn more about IPM please go to the following EPA link: http://www.epa.gov/opp00001/factsheets/ipm.htm

Tree DoctoRx has developed a quarterly soil health conditioning program, using organic-based fertilizers, mixed with humic acid and soil penetrant. By using organic soil conditioning methods in your yard you can increase the health of your trees, plants, and flowers. “We believe in using the most advanced application methods to fertilize our trees and landscapes. If trees and shrubs have fertile, microbiologically healthy soil to live in, they are less susceptible to deficiencies, root diseases, drought stress, and insects.”‚ John K. Pape‚ President / Certified Arborist.
