What Happened to Clematis?
I have a Vyvyan Pennell/Celtic Skies clematis. This is its second growing season. It was happily climbing up my trellis and then one day, the leaves up top were just black and wilted. The bottom of the plant looks good--still green and growing, but the upper part looks terrible. Any idea what could have happened? Also, should I cut the blackened part back to see if it re-grows?
I should also add--this is my first post here on the GardenWeb Forums, and my first time trying to grow a clematis.
Thanks a bunch for any help you can offer!
