Frosty Freezy Carmichael

We've had several consecutive days of frosts or freezes (3? 4? 5?). I'm starting to see some casualties. Nothing's dead, but I think I'm going to end up with a fair bit of top-kill on the following: Mexican bush sage, echium, my veggies, some herbs (esp. sage) and a few others. I'm keeping a close eye on my 9 citrus trees. I've been covering them with plastic tarps or bubble wrap (whatever I have handy), but they're young and vulnerable. If this keeps up, I may go the extra step and wrap the trunks. It's not even winter yet!
