Nita,
All the advise given to you is correct on the treatment of blackspot
on roses. I would also like to add one more trick that is far less
toxic to you or your roses, and far less expessive. I have just tryed
this method this year (new roses here too, with new soil) and I am
very pleased with the results. I have no hybrid teas here, just
English and old garden roses, but it should help any rose. (also
works for powdery mildew.)
Spray at least twice, with about a week in between treatments. With 1
tablespoon baking soda, 1 tablespoon cooking oil, 1 teaspoon of
(lemon is best) liquid hand dishwashing soap, to 1 gallon of water.
This is enough to spray (till nearly dripping) 60+ roses.
I have done this treatment only twice and have very little blackspot
left. The affected leaves eventually fell off and have been replaced
with healthy ones. I also have great soil, fertilize and water (at
the feet) well.
Sincerely,
