Q.leaf damage
It looks like most of the leaves have holes in them and some have spots on them also. The rose bloomed beautifully but now I don’t see any new buds appearing. What should I treat it with?
If the black spots do not move, they are not bugs. It sounds like her roses may have a fungus attacking them called Black Spot. The only way to stop it is to spray the roses with a fungicide for the treatment of Black Spot. Keep in mind that once the black spots appear on the foliage, they will remain even after the fungus that caused them is killed. The new foliage should be free of the spots if the fungus has been truly killed. Here is a link to an article I wrote on this subject for you:
