Perennial Garden Leaf Issues

I have several plants – Oakleaf hydrangea, black-eyed Susans, and coneflower – where the leaves have holes in them and may also have rust disease. The plants are growing, but they do not look very healthy. I am unable to find any information on treatment. I have tried water and soap, but it does not appear to help. I have not tried soap, oil and water, which was my next option. Removing the damaged leaves would leave the plant almost bare.
