Growing and maintaining trees is a science. If you want your trees to grow, bloom and beautify your property then you will need the help of professional arborists. Horticultural Services serves the tree care needs of individuals and businesses all over Central Contra Costa and nearby areas. Our seasoned arborists are dedicated to the protection, conservation of trees as well as the promotion of tree care. We are associated with some of the more prominent tree care and conservation organizations in the nation. Take a look:

International Society of Arboriculture
Founded in 1924, the ISA is a scientific and educational organization dedicated to fostering a better understanding of trees and tree care through research and the dissemination of information worldwide.

Integrated Pest Management
The National IPM Network is an evolving and cooperating group of universities, government agencies, and other organizations coming together to provide up-to-date, accurate information for pest management. See also University of California Integrated Pest Management Online.
