My neighbor has two trellises of roses. One is in bad shape, most of
the blooms are rotted and the rest are dying. MANY of the leaves have
black spots. The more covered leaves are turning yellow. There are
dropped leaves.

Everything matched the description of Black Spot.

The one thing I noticed was there were white spots on the roses,
particularly the outermost petals. They look like bleach stains--the
edge of the spots quickly turns from the rose's pink into a pure
white. They are *very* covered with these white spots. Far more than
most of the leaves with black.

Are "white spots" another, less mentioned symptom of black spot?
Or is this something else?
