I have a small garden shop in south Mississippi. I have hundreds of pansies in 4 inch pots. We are having temperstures in the late 20s tonight and tomorrow. If I water them down real good, will they be ok? Same with dianthus and snapdragons? All theses plants are facing east but they also are subjected to north winds.

The pansies might be ok, and the snap dragons, though less so. Both are likely to suffer some damage. The dianthus will likely not survive though without some really good protection.
Water them well. If you have twinkle lights, weave them among the pots. Or you can fill jugs with hot water and set them among the plants.
Then cover them all with cloth sheets.
