The week beginning January 12 was cold with a moderate freeze; California's orange crop was badly damaged (~$1B). One day Sailor's water dish was a block of ice that didn't come free enough to remove until noon. Here were the temperatures (all clear days and nights):

The orange tree seems to have been only lightly burned by the freezes; perhaps the Christmas lights I put around the drip line under the tree helped, as well as the spraying lots of water on it every evening. There appears to be very little, if any, real damage. The oranges are not dropping, which seems to be a good sign; they are still too sour to squeeze into juice (usually good around February 1). Photos are from the roof and back yard.

The eugenia multiflora hedge against the fence between our back yard and Ellen Mann/Renato Tuazon's back yard is more sensitive to freezes, and despite spraying with water every evening, it was significantly burned but shows little damage to the inside or lower levels of the bushes. Recall that this hedge has been frozen and killed to the ground once, sprouting back the next August, and killed back to 1 yd high sticks once, so this looks like only light damage comparatively. Perhaps failing to prune it in the fall, leaving lots of top foliage, helped too. You can see the tan/brown areas where burned/dead - pretty completely above the fence line - but green below and within. Photos are from the roof and patio - the last weeks later. (The ginger is in the courtyard off my bedroom; it will survive.)

Here is a shot of the eugenia hedge after pruned back down to the fence height and most of the dead parts removed (3/8/07); when it has recovered into a lush hedge again, I'll show it too.
