I had a bunch of it a few years ago, but it cleared right up on its own.

Be sure to carefully rake up and dispose of any affected foliage when the time comes -- the spores can overwinter rather easily. And it might not hurt to consider a dormant spray next winter.

Otherwise, there's not much you can do to control the problem now. Rust is seldom a fatal condition - pretty much just cosmetic in nature.

This is all good to hear. Hopefully the predicted warm weather this weekend will prevent me from getting rust also.
