Default problem with my roses-need help

Interesting. There are only two roses amongst my 100 plus roses which
exhibit this phenomenon of getting damaged by the rain also; one is Blue
Ribbon and the other is Sheer Bliss. Just two ... I wonder ...

I wonder if it is a function of certain kind of petal weight and colour
combination. All the roses the three of us have mentioned so far - SdlM,
Blue Girl, Blue Ribbon and Sheer Bliss are heavily fragrant as well as
lightish pink to mauve roses, aren't they.


Petal weight has definitely been a suspect in my mind with Blue Girl.
She has such thin delicate petals.

As far as anything else goes disease-wise, I've had a bit of problem
with black spot which was easily remedied by spraying. Both of mine are
more or less isolated (though the two are not far apart) so they get
plenty of air flow. No sign of thrips or anything else - just these
tannish edges on the outer petals that looks suspiciously like water
damage. I've only had one other rose on a different bush show the same
type of damage and this was a bloom that was pressed up against the
house where dampness got trapped between those couple of petals and the
house. That bloom was in a cluster and it was the only one that did
that and those petals on that bloom were the only ones that showed that
damage.
