black wilt on clematis

Asked June 1, 2020, 6:43 PM EDT

How can I get rid of black wilt on my clematis? I cut my vines down to the ground last year and removed all of the vegetation in the fall. The vine is coming back, but now the black wilt is back. This has been an ongoing problem over the past 3 years.

This site gives cultural controls to reduce the chances of clematis wilt:

It is a difficult disease to manage, once established. Since this is an ongoing problem, my recommendation, which may seem extreme, is to take out the clematis and wait a couple of years before trying again.
