Scootini

Do you know the name of the clematis? Is it getting enough water and did you mulch around it? It could be several things possible even the dreaded "wilt" if it's a type 2. Where are you located? Do you have high humidity?

All that aside once a section of clematis wilts all you can do is trim off the wilted part (always discard it in the trash not the compost pile).
