I also experience problems with mildew. The answer for me is to cut them back hard when about through blooming (end of June). They fill back in quickly and give me a second bloom in September. And, yes, they reseed like crazy, but are easy to pull out where unwanted.

Mine are not ratty looking and I have no problem with moldew or mold in my area. They add pretty blue/purple color to my garden.

These are weedy and very hard to get rid of, with deep roots and the ability to regrow from a fragment. They reseed like crazy. Also, they get mildewy and ratty looking in mid summer.

On the plus side, they do look pretty when blooming in late spring.
