how to prevent from frost damage

My new to me helianthemums got frost damage. I see some green shoots trying to grow. Do I prune back the dead looking parts or leave it alone? Also to prevent more damage. Can I just put a cardboard box or basket over the plant, some easy way to cover them at night?

I live inland from the San Francisco Bay area.

You are still in frost season for your area so I wouldn't do anything now. Just cover it on nights when you will get frost and uncover it during the day so it doesn't cook, especially if you are going to get sunny weather.

I would not prune or try to neaten-up the plant for another month or more. I like to just let things go for the winter as you can damage new, tender shoots & sprouts when trying to remove dead material. So, I wait until spring when the plant is definetely awake for the season and starting increase it's growth rate.

There is a floating row frost cover you can buy...and cut to size needed. Home Depot has some.

PS: How did your pittosporum problem come out ?

I finally got tired of looking at them and severely pruned them back. The ones with less brown leaves are growing back and look healthy so far. Two that had a lot of brown leaves are dead.
