Our average December high in this part of Volusia county is the mid- to low-70s. It's reached or exceeded the average only three times this month. We've set one record low, and several record "low-highs."
Freeze damage in the garden is on par with last year: Bananas killed to the ground (several were at bearing stage for next year--three year cycle in my garden). All tropical crops are dead or burned to the ground. Blueberry leaves are bright red. Cruciferous crops are fine, but growing slowly. Peas were damaged by our several days of low-20s, but might recover when the weather warms. My poor tomato seedlings are hanging on, but they haven't grown a centimeter since they sprouted. They'll likely succumb to disease, since they can't "grow out" of any problems.
