Hi all,

I'm considering adding Bright Eyes Phlox to my garden but I've heard mention of a mildew problem that they seem to attract. This page says once you spray them, i.e., only once, that usually solves the problem.

Does anyone have any experience with this?

Thanks in advance!

Phlox are prone to powdery mildew. 'Bright Eyes' is reported to have some resistance so isn't one of the worst. I'm doubtful that only one spraying would be sufficient if you find it has more mildew than you wish to tolerate - the level of mildew also varies depending on the weather in a particular year. This article on powdery mildew may be of interest:

Thanks Sue, do you know if the mildew spreads to other plants in the vicinity?

As far as I can tell there are two species of powdery mildew fungi that can affect phlox and both of them can also affect some (but not all) other plants. It would only affect plants susceptible to those specific mildew species, and, there are many other fungi that cause powdery mildew on other plants but not phlox. It can just show up on its own too, carried by the wind.
