There is no cure for kauri dieback disease, and the disease kills most if not all the kauri it infects. It can be spread by just a pinhead of soil, and you can't tell by looking whether a tree is infected or not.
There are several physical symptoms of kauri dieback disease and although the absence of these signs doesn't mean a kauri tree is healthy, it is worth keeping these symptoms in mind.
Assessing kauri trees for symptoms is critical in finding where the disease is located. The most common symptoms associated with kauri dieback disease are below:
1. Bleeding Gum
Basal trunk lesions. Not all infected trees show a trunk lesion, and not all trunk lesions are caused by kauri dieback disease.
2. Yellowing of Leaves
Kauri tree leaves could turn yellow as the disease takes effect.
Kauri dieback disease can take years to show, treat every tree as though it is infected.
