Preparing for a Freeze

We're expecting temperatures in the mid 20s and rain mixed with something called snow. It won't stick, I've read, but it doesn't usually come down to the valley. When we want to see snow, we drive up to the mountains.
Anyway, the citrus plants need to be protected from such cold temperatures, so I went about the garden putting frost protection on the lemons, oranges, and limes. I still have to rig up protection for the mandarin and the kumquats, which I'll do tomorrow.
I thought my lemon tree looked as if it had a visit from Christo and Jeanne-Claude after I wrapped it in its blanket.
