Will Agri-Fos help stop fungus already on a willow tree, that appears to have dead branches on half the tree....
Or is there any product to help on this? The tree is six years old.
The first thing you should do is get the tree examined by a trained arborist. The arborist will be able to tell you what type of disease/fungus the tree has and whether or not it can be saved. Fungicides in general work best as a preventative or when used right at the beginning of the disease.
