I am new to clematis! Yay!
So I planted two jackmanii (got them from wal-mart, unspecified cultivar) and I think both got bit from clematis wilt. One entire branch on both turned a crunchy brown. I cut it off asap. How do you guys treat or prevent this? Isn't it a fungus? I already spray with daconil and sulfur on an alternating pattern for my phlox, hollyhocks, pumpkins, and roses. Should I add the clematis to the rotation?
Also, I got a niobe and Avant-Garde I'm ready to plant. The avant-garde is from a local nursery so it is very large, about 3/4 feet. The tag says 8-10'. Are they vigorous? I am putting it out front and it needs to get about 10'.
Don't know anything about the niobe.
I am getting conflicting information on if these are group a, b, or c's. Silly internet.
Let me know ;0.
