Hunkered Down for the Cold

We've had a mild fall and winter so far.  But, that is going to change in the next 24 hours.  As I write this, we have an Arctic cold front barrelling down on us.  They have been talking about this on TV for a week and I've been concerned about the beautiful lettuce that we have growing in our hoophouse.  

The hoophouse is unheated, but lettuce and other greens survive quite nicely in there during the winter.  However, if the weather gets really cold, they will sustain some freeze damage on the tips of their leaves.  This makes them somewhat unattractive and less marketable.  So, in an attempt to keep this from happening, we have covered the lettuce with a double thickness of row cover.

We have also piled some of the leaves from our "Leaf Mountain" (see Dec 17 post) all along the west side.  We're hoping this may help as well.  Guess we'll see.
