How shall I treat my sick bush?
I have a quince bush that has mottled, shriveled leaves. When I turn the leaves over to the underside, there is brown " dust" or dry residue in the rolled up edges of the leaves. The infected leaves eventually die. It's all over the bush and I'm afraid I'm going to lose it.

"Hi,

Thanks for writing. It sounds as though your quince may have rust, a relatively common disease. Learn more about quince rust here: http://urbanext.illinois.edu/focus/cedarquincerust.html
