Does being near or under a tree make blackspot worse? My Kentucky Derby
is
always COVERED with blackspot, and no amount of anything will keep it from
looking pitiful.

The sun helps to keep the leaves dry, and direct sunlight helps to keep the
spores from germinating, so its position in partial shade may have more to
do with it than the variety. I don't have that variety, but I have noticed
that the roses in *full* sun have noticeably less fungal disease in general,
than those who share their sunlight.
