or there is one that uses milk and water spray it on or the shop bought rose clear.
Just make sure all leaves are picked up and burnt or binned they carry the spores for next year.
Hello
I have around 90 rose bushes and suffer from black spot, i either use a manure tea or the home brew as teresa said, I also use rose clear, In winter spray the ground with jeyes fluid this helps kill the spores.
