How much will you miss outdoor gardening in the next few months?

-15? If you mean Fahrenheit, that's -26c!! It's amazing things survive

 

Good heavens @Goldenlily26! Please remind me where they are. It sounds rather dangerous.

 

They live in a small town called Canmore, about 70 miles outside Calgary, on the way to Banff and Lake Louise. When the temperature drops that low there are constant warnings on the local radio telling older people to sat indoors and for everyone to wear gloves and not to touch bare metal surfaces. Your hands would stick to the metal.You have to wear wrap around sunglasses because it is usually very sunny but your eyes water from the wind, then the tears freeze on your eyelashes and you cannot see. When you breathe in your lungs hurt from the cold air. I took my son's dog for a walk, not far because he had to keep stopping to remove the balls of ice which kept forming between his pads.
The walk was magical because what little moisture there was in the atmosphere was frozen into minute ice crystals which sparkled in the sun. It was like walking in fairyland. A stunning experience but not where I would enjoy living permanently, the Rockies and pine trees were covered in snow and the river was completely frozen over, a real live winter wonderland.
Yes, sorry -40oF.
