Judie from San Diego, Ca writes
The Bonide Copper Fungicide can be used on a variety of shrub species, but since the label does not specifically mention indian hawthorne we would recommend testing a small spot of the plant first before applying it to make sure no adverse effects occur. We would highly recommend having someone local help you determine what is causing the yellowing of the leaves as it could be disease, insects, or nutrient deficiency.
