Urban trees can be affected by numerous pests, diseases, and disorders. These range from pollution, mammals, viruses, insects, bacteria and fungi. Disease diagnosis is one of our areas of expertise

Various symptoms that may indicate the presence of Pests and Diseases

  • Toadstools and fungal brackets
  • Weeping wounds and cankers
  • Loss of vigour
  • Early leaf fall
  • Crown dieback
  • Early autumn colours
  • Cavities and Damaged bark
  • Curling, brown or yellowing leaves

How We Can Help

If you suspect disease or infections in your trees we can help. We will positively identify what the infection is, make an assessment of health and safety risks, and give you a schedule of recommended works necessary to treat or manage the disease. In the case of a notifiable disease, we will make a report to DEFRA or other authorities on your behalf. If the tree is protected Tree Preservation Order (TPO) issued by the council, or you live in a conservation area, we will make the necessary applications to the council for you.
