They can recommend watering, fertilizing, pesticide applications and other cultural programs to help maintain the long-term health and beauty of landscapes. Finding an Arborist Start by asking your friends and neighbors if they have had recent dealings with a tree care professional, and who they recommend. Call and arrange for visits by more than one company, so that you can compare their knowledge, experience, services and charges. What to Expect from the Initial Visit and Diagnosis During the initial visit, an arborist should walk around the property and discuss your needs and the services he or she can provide. The arborist will be able to answer most of your questions, but may not have all of the answers immediately.
Tree health is a complicated field of study, and no one knows it all.
A good arborist will collect samples, consult other experts and references when warranted, and base recommendations on the proper diagnostic procedure. The initial visit is also a good time to ask about the arborist's credentials. In the State of Connecticut only licensed arborists may advertise, solicit or contract to prune, cable, fertilize or spray trees on a commercial basis. Ask about the arborist's license. Connecticut law also requires all companies with employees to have workman's compensation insurance.
