Help for my Japanese Maple tree

Asked May 24, 2020, 11:59 AM EDT

My Japanese Maple tree seems to have been hit with verticullum wilt bacteria. I am looking for a product that i can put into the soil to help save this tree.

At this time, there is no chemical control for this disease. Rather, the tree is managed to maintain strength and resist decline as long as possible. These fact sheets from Cornell University Cooperative Extension (http://ccenassau.org/resources/-verticillium-wilt) and the Moron Arboretum (https://www.mortonarb.org/trees-plants/tree-and-plant-advice/help-diseases/verticillium-wiltt) have information on management.



My actual question is not about a disease of the tree, it is related to a root that is reportedly choking the tree. If I send a picture to you, can you advise me which root we should cut into over a period of a few months?

Thank you,
Lisa


Verticillum wilt is a fungal disease that lives in the soil and attacks a tree through a wound to the bark. A root choking the tree is a different problem, probably a girdling root which is near the top of the soil and cutting into the trunk, restricting the flow of water and nutrients. That is something that you should have a certified arborist attend to. The entire tree needs to be examined in a detail that is not possible through photographs. You can find a certified arborist that works in your through the International Society of Arboriculture (ISA-arbor-com).

If I send you a picture, would you be able to identify the root you think is choking the rest of the tree?

I'm afraid a photo can't suffice for this problem. That is something that you should have a certified arborist attend to. The entire tree needs to be examined in a detail that is not possible through photographs.
