Hi Jan, I have found with our roses that picking off leaves with blackspot as soon as you notice them and taking the leaves out of the garden so they cant re-infest; along with making sure the roses are healthy well fed with an organic fertiliser which has trace elements such as a seaweed solution along with some manure; watered enough but not too much; and also (important) changing watering regimes so that water is not sprayed onto or splashes onto leaves and watering doesn¹t occur in the evening so that the plant is not damp... This combination fixed¹ our blackspot. Plants which three years ago lost all of their leaves to blackspot, now only get one or two affected leaves per year and when I notice these I pick them off and feed the plant. I hope this works for you, pruning the plants to allow more airflow may also help.
I am getting more and more interested in edible flowers and roses are great! Add them to wine sauces, dip them in egg white and sugar and sprinkle over cakes/icecream, add them to salads, butters, drinks. The white bit where the petals attach to the plants can be bitter (so cut off).
