What is this?
Bacterial leaf scorch is from the bacteria xylella fastidiosa. This bacteria is spread from several types of insects that can be typically found on trees, including leafhoppers and spittlebugs. The bacteria hitches a ride on these insects, and then is transmitted while the insect feeds on the tree. Oaks are the most susceptible, including: pin, red, bur, shingle, and white oaks. Other tree species that are prone to bacterial leaf scorch are: sycamores, sweetgum, American elms, sugar maple, and red maples. All of these trees are important species for the area, so we encourage you to protect your trees as much as possible. If you have these tree species on your property, please keep vigilant and look out for signs of bacterial leaf scorch or other diseases.
How do I fix it?
While there is no cure for the disease, you can keep your tree going and help it bounce back temporarily. There are a variety of products on the market that can be applied to extend the life of your tree, and help it continue to produce leaves. Please consult a licensed tree expert before applying chemicals or for guidance about which treatments will help keep your tree alive.
Can it be prevented in the future?
There is no cure for the disease, but being on the lookout for noticeable changes in your trees, especially oaks, and calling in experts to test for the disease, can keep your trees happy and healthy in the long term.
