Does anyone know if this Downy Mildew that attacked pretty much all Impatience in Florida is dead now or do we have to endure another year of it this year? I bought 4 flats yesterday and
the gardener said that its a catch 22 . Hopefully its not going to happen this year

I think a lot of it has to due with how the plants are cared for. Here is a great article to check out http://e-gro.org/pdf/Bulletin_1-8_Impatiens_Downy_Mildew.pdf

The disease is still around, Alice. But you won't have to worry about it if you plant New Guinea impatiens instead. You might want to check out this article from the Palm Beach County Cooperative Extension Service. It lists fungicides available to homeowners if you do see signs of mildew (and act quickly if you do): http://palmbeachcountyextension.files.wordpress.com/2012/01/downy-mildew-on-impatiens-2-2-2012.pdf

I know Doug but the regular ones look so much nicer, And in my strawberry jars they look magnificent. Don't know if i would get the same results as the New Guinea ones

Maybe you will get lucky, Alice, and not have it show up.

I have read somewhere that half strength milk and water sprayed on the mildew should kill it???
