I have a Clematis in a large pot which grows leaves each year but which
hasn't flowered within my memory (which isn't that long).

At the moment I am assuming that it is an early flowering variety and
isn't flowering because it is taking too long to start growing each year
(it is neglected - no winter pruning).

I assume that there is no easy way to identify this without a flower.

Try some leaf close ups and stem close ups, a shot of the roots if its
in a container would help as well (dont dig it up, just what hanging out
the bottom). It may not give a positive ID but I may be able to exclude
some groups.

Also details of when and how you have been cutting it back.

Will post some pictures, thanks.

On the cutting back front, how about "never"?
Is "never" good for you?

Have you ever fed it?

Yes.

It most resembles a group two type which needs cutting back at some
point in summer. It definitely needs repotting! I would expect it to
have buds visible in late march and be in flower May June.

It is however very difficult from just the leaves to be sure, but even
if I am wrong it needs cutting back

Thanks.

(1) When in summer should I cut it back? I am obviously concerned that if
I cut it back when it is in full leaf then it may lose all the energy
producing stuff which goes into the roots. If cut back hard should I
expect it to bud and grow on again during the summer/autumn?

(2) The pot is (relatively speaking) huge. Are you saying that the compost
needs removing and refreshing? I hope you aren't saying that it needs an
even larger pot! :-)

Cheers

Pot is not huge! but at bottom end of what is needed, if you are
intending it to stay in that size pot it will need repotting at least
every other year, September is a good time, cut it back remove it knock
a load of compost off, chop the roots by 50% then repot into the same
pot. If you dont want to go to that degree of trouble it needs something
along the size of a half barrel, use some soil in the mix. a big pot
like a half barrel should give you indefinite years if fed and top
dressed each year

O.K. - thanks.

For the moment I will give it a feed and see if it bucks up at all.

Given the spindly size of the plant above ground I had expected it to be
quite modest in its need for a pot.

With a following wind I will repot it in September and post a picture of
the roots.

Cheers

I was wondering about the depth of pots in which clematis is grown. If
the variety is susceptible to clematis wilt, can the clematis be planted
deeply enough to survive it?

Sorry about the lack of pictures; overtaken by circumstances.

However it has just started to flower so I will try and post some pictures
soon.
