My new rose bed was planted in July and everyone of them except Glamis Castle pushed out new growth that was very healthy. I thought GC had BS so I sprayed and the big black spots didn't return but small brown spots took their place. Yesterday I checked that there were no others with these spots and they were all ok. There is also a young tree in this bed which had perfect growth. A moment ago I went to check them as I do every evening and not only is GC covered in these brown spots but other roses have it on the lower leaves as well. It started on the lower, older leaves with GC but it is now covered in it. Even the tree has brown spots and it even has a few pin holes where the spots ate through the leaf.
This is GC. I had to put my foot below it or the leaves would have been lost in the background.

Dogwood with spots and holes.
The camera wouldn't focus for me so I apologise for the poor quality pics. There has been no humidity or other weather related problems and my neighbours have not sprayed or fertilised their pastures recently. What do you think it could be? I am starting to panic as it has all happened so fast.
