Alice ~ your zone is similar to mine. I leave oregano out and it overwinters fine here. I also have assorted lettuces, swiss chard, cilantro, snow peas, onion and garlic in ground and growing.
I do have a bed of beans growing and they don't like the cold. I covered it with frost cloth and they are also fine. I wonder if your spinach would grow outdoors over winter also.
I didn't provide cover for the fruit trees but all appear to be fine. I have two lemons, a satsuma, a kumquat, a pomegranate and an olive. I do need to get more frost cloth to protect them as the containers are larger than I want to move...
My tomatoes are done for the season. I tried keeping some in the greenhouse through winter in years past and found I fought white flies all winter with little fruit production. I hope you are able to do well with yours.
The foliage is toast on my bed of peppers but I don't think it was a hard enough freeze to damage the peppers. I will harvest them this weekend and pull the plants. I will probably replant that bed with potatoes after the first of the year.
Now that our winter is over, what lived and what died?
I chuckled when I read that. I can only wish our winter was over.
At least being able to winter garden helps my winter mood.
