Most petunias are very rain-sensitive -- the flowers often get damaged
from rainfall but then grow back quickly. The are full-sun plants,
though, for the most part, so they might not be getting enough sun
where you've got them. Also, you say you are adding "a capful of
Miracle-Gro to the soil" -- is that directly to the soil (undiluted)?
If you are using the concentrate form, I would definitely stop doing
that. That stuff needs to be watered in using the correct dilution
rate.

Good luck -- hope this helps!

Thanks for the info, I kind of suspected it had something to do with
the rain and not enough sun. The MG I'm using now is the "Pour &
Feed" with the blue cap, it comes pre-diluted. You just pour one
capful directly on the base of the flower. It's a bit more trouble
doing it that way, and no doubt more expensive, but the other flowers
seem to respond well to it.
