Diseased phlox

GallopingHorse(7b)September 7, 2012

Any ideas what hit my phlox in early August? It was doing great, then all of a sudden wilted and turned brown (as in the photo). This happened sporadically to several phlox plants in the same garden bed. I'd welcome any help with this one.

Thanks.

I've never seen them turn that color before.

If the death was sudden (one or two days) then I would guess that it was some form of root rot or some animal (like a vole) ate the root mass underground.

Yeah, I was thinking vole also .
Galloping Horse, what did the roots look like when you pulled up the plant?

Thanks for your answers. The roots were still attached, so I doubt it's voles. When I've had them in the past, I'd lift up the plant and there would be no roots, so the stem just lifted off. I was thinking maybe a soil disease, but I can't figure out what kind.

But isn't that a phlox there to the left that looks green and healthy?

Yes. Some of my phlox is fine, some (not just the one pictured) isn't. It's a mystery. But I saw a shoot coming out of the ground this afternoon where this one was, so maybe it's not entirely dead yet! I'm wondering if the extreme heat (the 2 weeks of 100-ish weather in July) may have been too much for it. Again, most of the other things in the garden did fine, even with that heat, so I just don't know.
