Clematis w/different pruning requirements
Hi, I'm afraid I've made a huge mistake. I live in zone 5, in Syracuse, New York. This is the first year I've grown clematis. I have a 7' tall x 4' wide arbor and have planted Sweet Autumn, jackmanii, fireworks, lasurstern and blue angel to grow up the arbor. They're going to be one gigantic mass of vines and I'll have no idea of how to prune what! Will the Sweet Autumn Clematis be as aggressive here as it would be further south? Any suggestions? Thanks so much. (I've posted this to the clematis forum but wanted to hear from those of you in my area who may have had a similar situation).
