If you believe that your tree is unhealthy or dangerous, it would be prudent to consult a professional to establish the cause and extent of the problem and to determine the appropriate solutions. There are an extremely large number of pests, diseases and disorders that affect urban trees; including fungi, bacteria, insects, viruses, mammals, chemicals, and pollution. Trees have in-built defences including compartmentalisation and various chemical compounds that allow them to survive most situations, but occasionally trees become sufficiently stressed so as to require intervention. Arbconsultants has enormous experience in the diagnosis of tree pests and diseases. Our consultants are highly qualified so as to solve the sometimes multifaceted interactions between pathology, entomology and the host tree and Arbconsultants will often facilitate remedial solutions to the disorder.
