Normally this tray of herbs (& a few other things) stays out on my glassed in sun porch. The porch rarely falls below 30, but this year–& during other “polar vortex” years– it does get colder.
I haven’t brought the herbs in before this year and in previous years, I have lost some of them. So this year, I took no chances. I brought them indoors.
Initially I thought that it would be for a night or two. When it became apparent that it had to be longer, I moved them into a well lit place and resigned myself to living with them inside the rest of the winter.
Anyway, at least it’s a fragrant problem to have.

Below 30 inside! Oh my! That is too cold even outside!
And now you know why I call it the frozen north up here! Today it’s a relatively balmy 36 degrees–for the high–with a gusty 50 mph wind. We won’t even talk about what that feels like. Tomorrow the high won’t even be 30 and Wednesday with highs are going to be in the mid 20s with snow. The lows might hit the single digits. Yes, this is a bit colder than normal for us, but sadly, it’s not ridiculously cold–it’s about average for early February.
