My salad garden has been coming along nicely (lettuce, radishes, and carrots) and will have to be protected. I'm planning to drape a sturdy tarp over that side of the raised bed and find some good heavy stones to hold it in place overnight. The pots of camellia starts will have to be secured, either on the porch up against the wall or else in the garage. I doubt there's much I can do for the tender new leaves on the fig tree. A hard freeze this time last year took out the new growth, but more leaves sprouted immediately afterwards and there was no lasting harm. The daffodils should be fine. Did I mention that my newly planted daffodil bulbs are blooming like mad? I counted almost three dozen flowers this morning! I doubt one night of cold will hurt them, but I'm considering picking a vase full for the house just in case.
I'm not worried about the newly planted crabapple tree---because it's still nothing but a bare stick! At least in that case there's no tender new growth to lose. The pomegranate tree will be fine. It's covered in a flush of tiny leaves, but it's in the warmest and most protected spot in the yard.
What else? I think all that will be left to do after covering the raised bed and moving the potted plants will be to do one final scan of the yard and porch for loose items. My container of seed potatoes has small sprouts and will have to be moved into the garage for the night to protect them from the freeze, too. That should be all. All that I have any control over, anyway!
