Q.Clematis Dying
Help please – I lost one of my 3 baby clematis(es?) this way last year . Base beginning to dry out but top of plant is healthy and has buds too.

I do, very much, see sign at the tips of the leaves, and indicated by the undulation of some of those leaves. The disease can affect plants in many ways, and covers a vast range of species of fungi and bacteria. Some species will cause different symptoms than others, and to know which you have will require genetic testing at your local extension service. All will have the same outcome at the end. But again, I urge you to take samples to your local extension service. This article will help you to find your closest one. The link at the bottom will take you to the search page.

This looks like Clematis wilt, very unfortunately. This isn't something that can be cured. Treatment is possible to prolong the life of the plant, but this has no direct cure.

Thank you so much - unfortunately I can't access these centres as I live in UK!

Thank you, BushDoctor. But on reading further about about Clematis Wilt , I understand they affect the leaves too. The vines - as you may see in pics I had sent - have health leaves and new ones appearing too, same with lots of flower buds. Is it ok to cut the plant to the base at this time?
