Brown spots on stems, black leaves, stems falling over
I have 4 Annabelle Hydrangeas on the east side of my garage. I planted them 2 years ago in the fall. Both years they come back well in the spring and look healthy. Gradually they develop dry, black leaves. Then some stems get large brown spots and fall over at the base of the plant. I figured it was a fungus and tried a fungicide but it is difficult to apply all over the plant. Ideas?
