Unsure if our clematis has clematis wilt
Hi, please could someone tell me what might be wrong with our clematis? We have never managed to get it to flower in 2 years it was fine then suddenly we woke up the next day and it looked like the photo attached. I’m unsure if it is clematis wilt or something else. It’s such a drastic thing to do cut it back to the root if it’s not clematis wilt which is why I thought I would ask you all first. Any help would be appreciated.
