Well if they are well covered in snow that should help. Those are my most favorite plants, unfortunately I can't seen to grow them...
When we were hitting the minus 6 and consistent below normal cold weather we had no snow cover. I am hoping they will be ok, I think they will. They are rated for even lower zones than we are.
We are zero right now. Once it warms a little I will go out and bucket off the drive way. The sun will be out, once I get a lot of the snow off it will melt the drive. The yard has a while to go. But are temps are heading up up up lol at least to high 40's in the next week.
You can see the deer tracks where they have come up and munched on my plants. I got a out in the yard measurement of 10 inches.
The weather guys are saying they have never seen a storm like this, the moisture coming from the pacific all the way across the country at the same time, then it started to draw moisture from the gulf. And with Colleens cold air coming down here it turned to snow.
The moon was full last night, with the snow it was like daylight
