Well, I've been getting my hands dirty for awhile, but new to Clematis. My neighbor has one on her mailbox that is gorgeous in early summer but looks rather scary after that. I have 2 a pink one (name escapes me) and Snow Queen. I bought an obelisk for Snow Queen and will get it in the ground this weekend. I've got clay so I'm mixing in potting mix and a bit of compost. Does that work? I'm not expecting much growth but want it to get settled before winter. I know I don't need the obelisk, but it will keep me motivated :) Are there other things I should know about coaxing these plants through Fall and Winter?
