Thanks Bev and Greg for your kind thoughts..
There is now a couple of inches of snow on top of the pots. That should insulate them a bit against the cold.
I am thankful to have made it back home, although it was tricky in spots, but few people on the roads.
Think I will stay in now until it gets a bit warmer.
(I was looking for an excuse.
)
Linda, enjoy the warm while you can. Hope your freeze is not too bad.
