Thanks for your reply. I'm going to do this tomorrow morning. I've never
mulched before but this year I divided a lot and thought I would protect
them. We get winter temps of -20 C, or colder, and then mild spells, so
there can be a lot of heaving. If there is good snow cover, it provides
its own insulation, but some winters don't have enough snow.

Our soil is already acid because we are surrounded by cedar woods (or

outside, even though I haven't finished my Christmas cards yet!
