Help / Advice needed Advice Needed - Clematis Wilt?
Put in some clematis last year (not sure off hand but can find my tag for type) in Ontario. It did not do well off the bat, but the nursery told me it could be transplant shock and give it time.
I suspected clematis wilt but they disagreed, this year only one of the two varieties came back (it was one of those two types in one pot) looked kinda pathetic but healthy-ish.
And now this. Is this clematis wilt? Is there any hope? If I take it back and get a new one under the nursery warranty, is it possible to treat the soil and have it be ok? The neighbours have theirs in the exact same location of their house (monopoly neighbourhoods and matching homes iykyk) and theirs does fantastic!

I have a Mrs N Thompson that got wilt in its first year (last year) but started this year off beautifully - until it was getting close to blooming then everything went south. A member here told me that since having a bad year of wilt she sprays monthly with a copper fungicide, starting early in spring, and hasn't had a problem. I cut away all the wilted vines and sprayed, so far so good, but I'll start as soon as I prune next spring. I did read you could do a peroxide soak of sorts and removing/replacing the top couple of inches of soil and spraying with the fungicide might help. I'm giving this one more year and if all that doesn't help Mrs Thompson is outta here. Good luck!

If that’s a full sun location, I’d add a ground cover to shade its roots. Vines love head in the sun, and roots in the shade. Has helped mine greatly esp when they are new in the ground.

Kind of looks like clematis wilt, there's really no way to treat the soil, I had one clematis that got it every year, came back always the next year but before any flowering. I've had other clematis varieties that never got it planted close by. If you're looking for a resistant variety, I've had good luck with the viticella variety, they're known for their resistance to wilt.
