if the forcast calls for a chilly night you could set up some row covers (i use cloches but that would be a whole lot of cloches...)
around here they always say wait for the nighttime temps to get above 15, but maybe that's cuz we're more likely to suddenly have a night around zero out of nowhere. like you said, it's not all your plants...
