Star, what an admirable endeavor. I'm sure in a few weeks the petunias will be back to their usual size. just be patient..no use crying over spilt milk as they say. the marigold might just make it, I'd keep both in the conservatory until they're well enough to go outside. perhaps relocate them {when they do go back outside} to a spot that has a windbreak so they don't get buffed around again. good luck!
