The plants themselves look healthy (the leaves in particular). The only
thing I can think of by looking at the picture you posted is that the plants
may be too wet or they may have a fungal disease.

What I mean by too wet is that water sits on the flower heads for prolonged
periods maybe in a shaded spot. It seems weird though that all of them are
turning out that way. It usually happens to select ones. Pansies do best
in a well drained soil in full sun. They are very particular about water
sitting on them and will rot easily. Sometimes the plants will also develop
root rot where they break off easily at the stem entering the ground.

The fungal disease sounds more like what you have. Sometimes is comes from
unsanitary conditions from the original grower. Pansies are prone to a
fungal disease that vinca flower is prone to also. That's why we warn
customers not to plant pansies in the same spot as vinca flowers were
previously planted unless a fungicide is applied prior to planting the
pansies.

I am by no means an expert, but if they were mine I would check into the
things I've listed. You may want to spray them with a fungicide meant for
pansies (check the label) and see if that turns them around or check the
overhead watering situation.

Good luck.

I planted some nice healthy pansies a few weeks back, and they looked
great for a little while. But now, all the flowers look diseased.
I've clipped off all the flowers to start anew, but as they bloom,
they all look mangy, with brown rotten-looking, almost moldy edges.
I've posted a photo at http://www.inhouzemusic.com/pansy.html.

What's causing this, and is there any way to treat the plants without
digging them all up, discarding them, and starting over?

Thanks!
