Question
does sphagnum peat moss need any special care during the winter?

Answer
Hi Dillon,

Not really.  The only thing would be if you want to use some, you'll need to keep it in a location above freezing since it does have enough moisture to freeze.  It will be too solid to scoop any out.

Good Growing!
