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?
I put coffee grounds on the soil, I was told that was good nitrogen for the soil, but I wonder if it was too much. Is there any way to counteract those coffee grounds. The plants have always been full of blooms.
The coffee grounds did not hurt it and if it was used coffee grounds, the nitrogen was not available. You have to compost coffee grounds to get nitrogen. They can improve soil by helping to loosen it with organic matter. Your plant may have bud blast. Here is more:

I have a clematis that grows well each year, but blooms only at the top. I really can't remember what it is, planted it long ago! I prune to a healthy bud in the spring (march/April), sun until maybe 2-3 pm Any way to make it bloom further down, or is that just its type?
This appears to be a late clematis, which typically blooms on this years growth. If it doesn't get cut down to about 18 inches or so in Spring, then it is probably going to flower only on the new growth at the top.

This clematis is 6 or 7 years old, and has bloomed purple in pass years.
It may be stressed! These articles should help:

I'd like to know how and when I could transplant my clematis plants from container to bigger containers. Also, is it possible to combine 2 plants together in 1 bigger pot? Thank you.
If the plants need the same amount of water and sun, it is OK to plant them in the same container. You can transplant in fall, but the sooner the better. It takes them a long time to resettle their roots and typically don't like to be moved. Spring would be preferable for the move since you are in hardiness zone 5. Most clematis are hardy to zone 4, so your clematis would do better if it is moved into the garage for the winter and watered only about once a month. A container offers little protection from the elements.

It should work since it will grow in part shade. Here is how to care for it:
