I was doing a quick survey this afternoon (we still have snow, after all) and saw that both the tree peonies I planted last fall survived! One has several red stalks emerging and the other has a few. I am very relieved. I've never grown them, and planting something so deep was a little scary.

Should I just let them fend for themselves, or should I cover them if it gets really cold (like in the teens)? Thanks.
