Here's how I prepared for last night's freeze:
This morning when we got up it was 23 degrees outside! I'm pleased to say that my plants were almost completely unscathed despite the bitter cold. The only loss was a few leaves on the fig tree (over where you can see a few leaves peeking out from the cardboard) but the majority of them were fine. The salad garden looked green and cheerful when I pulled back the tarp this morning, too. Tonight it's supposed to get just to freezing again, so I've covered everything back up now that the sun is going down.
One last thing....why, why, why must we continue to observe Daylight Savings Time?! I hate changing the time both times we do it in a year. I wish the powers that be would just pick one or the other and leave well enough alone!
