Over the past 3 days, I've seen the temperature at 4F and 5F on Saturday and this morning, respectively. We've got 3 outside cats who amaze me at their toughness. We built them a cathouse out of leftover insulating panels. We also make sure they have a fluffy old comforter inside their cathouse. In the mornings when I feed them, they saunter out of their house and feel warm to the touch.
Cats amaze me at how they handle the cold. And birds (we feed a bunch of them). But my plants do too. And they aren't provided anything to protect them. I took some shots of the ice that enveloped the bark and buds of some of my trees and shrubs over the weekend.
Here's my yellowood (Cladrastis kentuckea) bud encased in ice.
The bark of my young catalpa is frost-covered too.
January has been great (cold, I know, but great) since we haven't had any warm-ups. If we get some abnormally warm days, trees and shrubs can be tricked into growing. Remember April 2007?
As much as I hate to say it, I kinda hope it stays cold through February.
