It's such a short thickly-foliaged plant. I've noticed that if the weather
is wet and cool, it will have a tendency to develop blackspot at the
bottom
of the plant where the leaves are so crowded and nearly touching the
ground. I was wondering if anyone who grows this rose thins out the leaves
to get better airflow and if this is a good idea to try to control this
particular problem?

Hello again Mike,

The Diva Suprema! she of the balling habits, and blackspot
magnet. What I have done in the past is to make a support
system with willow cuttings similar to the one used to hold
up the heavy peonies, only that it has been mostly several
sticks of the same height placed around the perimeter of the
rose, to hold the lower branches up from the ground and about
15 to 18 inches from the trunk. I place about 10 and then
crisscross three or four all the way across and use some
copper wire to hold them together. Then I get to the
bottom of the plant and take anything closer to the ground
up to about 12 to 15 inches. At first it is pathetic but what
happens is that the inner branches start to curve over
the willow and pretty soon the whole thing disappears
between the foliage and the blooms.

It gives it plenty of air circulation and it is easier to clean
underneath if needed, as some foliage still grows at the
lower level. Here in Portland she is la diva divisima,
if there is a cloud in the sky, she is one slimy ball in
seconds. But I am so dense that I cannot give her up.
So now she is leafing and I am experimenting. I am
making her go around a support made of green wire
and instead of the usual fountain- like growth I want
to see if she would wrap herself around a column
weaving her branches in and out. She is a baby right
now, less than a year old and inside one of Leonard's
bathtubs, so we will see.

But indeed it is advisable to take the lower foliage
anyway. I do that even though we spray and still, the
closer to the ground, the more chances are there for
anything to crawl and cling to the foliage. And by
the way, Chamblee's sent me the SdelaM climber
and that guy doesn't understand that he is supposed
to stay down in the arbor. So Felcos in hand guess
what I am going to do tomorrow? That probably
will bring another hail storm like yesterday, sigh...
