The Dahlias cant catch the mildew that is hitting the Impatiens, but
they can get another form of mildew, edp. if they are planted in an
area where the air is stagnant, that is not moving.

Thanks Dave. The "sick" dahlias show no sign of mildew at all, simply
wilted as if not-watered (which isn't the case) and no new buds.
Probably pure co-incidence that they're in the same container as
impatiens but I wonder whether the sick imps have, in some way, done
something to the compost.
