We have viburnum tinus, 8 years old and very healthy, and 3 elaeagnus, again 8 years old and healthy. In the past month their leaves have become covered in tiny black spots, size of a pin head and they look like they may well die, leaves are falling off and they look generally sick. I treated the former with a general purpose spray a week ago but no help at all. Anyone with any ideas as to what I can do to save them.
Thanks for any help.
