We fell to 29 and stayed there. From 2:30 am on we ran sprinklers, we have them set up in zones and had to change zones every 10-15 minutes. The garden was a sheet of ice, the plants were encased in ice. The temps didn't get above freezing (at ground level) until around 8:30 this morning. The only thing I lost was two rows of sweet potatoes! The plants thawed out and are just fine, even the green beans and tomatoes (which have big tomatoes on them). I had to leave and get to the farmer's market, I was already running late, so we set the timer to shut off the sprinklers at 9:30. I didn't know what to expect when I got home.

Here is a photo taken around 8:00 this morning. The white "line" around the garden is an electric fence covered with icicles.
