I have 5 of the same plant from the same place, all of them in very differing states, despite all looking pretty much identical when I planted them. I fear one of them is dead or dying, 3 of them doing ok, and one of them looks fine but hasn't really grown at all. Any help welcome, my dream was for them to grow and provide loads of cover on the trellis above them, hard to believe they'll get anywhere near that right now

Alive but hardly grown:



Dying?



Three that are ok?

Water.
Feed.
And water.

Any plant that is trying to get established benefits from lots of water in the first couple of years. After the dry period we’ve had they’ll need even more water than usual. Give the ground a really good soaking every couple of days. Lots of water infrequently is better than little and often.

Ok thanks, I’ll up the water game. I assumed they were getting enough water as a few of them look pretty healthy, but I’ll do more.

You could check the planting levels for the five.

If I recall, they should be planted "under" the pot level.
Meaning under the surface by an inch or two.

There might be a difference.

I think that's the advice.

You could join and seek assistance from The British Clematis Society.

http://www.britishclematis.org.uk/

I can't vouch for how active or worthwhile they might be but I knew a previous editor of their newsletter.

They don’t grow linearly I feel, mine put a lot of effort into growing early spring and then basically stopped to flower. Jasmine the same, I’m now seeing growth from the Jasmine now it’s not flowering and perhaps the clematis will start again.

We set these in April so about 3 months ago. Water everyday and feed once a fortnight. I trained them along the fence every other day.
The type does matter, these are Montana. When we potted them they did not reach the top of the wall

Clematis roots don't like direct heat .. so if South facing cover the roots with stones ....It's what's underneath that matters ... if they've rooted they'll come back.
Montana is pretty rampant ... others are more delicate .... and require very gentle training .

Bang on….they hate direct sun on any part of the bottom few inches.

Thought I'd revisit this, as I'm still a bit baffled by what's going on.
I started with 5 plants. Two died, and the one in the middle below looks like it's on its way out as well. The other two seem to be doing ok though.....as a clueless 'gardener' I have no idea what caused the deaths or what I could have done differently? Any ideas? Can the middle one be saved?

The two that remain looking healthy seem to be doing a pretty good job of starting to cover the trellis, but not sure just two plants will provide the coverage I'm hoping for?

I would think that planting them under a canopy isn't helping things as plants need sunlight. The ones with access to sunlight look to be the ones doing better.

All the growth you can see in the second pic is coming from the plants in the first pic, so all 3 are under the same amount of shade, yet the middle one is dying, the other two doing ok....that's what's baffling me.

Evergreen clematis grows a lot slower in my experience than the other variety which drops. It also is famous for taking a long time to establish, with Armandii which I think you have they say the 3rd year is the one where it goes mad.

I’ve just planted a new set of beds and gone with a mixture of what you have, and also Jasmine which has spring into life a bit quicker. But I also have a none evergreen clematis growing through it and it’s far far faster growing but obviously in winter it all dies until spring.

Looks like classic Clematis Wilt - try a bit of research on that?

More help/thoughts please!

It looks like yet another one of my clematis plants has decided to die, leaving me with ONE out of the FIVE I bought. Getting fed up with this. I assumed the last two would be fine as they've grown a lot, I even saw some flowers appear etc, but no, suddenly it went south:





Last remaining one:

You are watering it in this weather yeh?

They take 2-3 years to root properly vs the non evergreen versions so you may have got unlucky planting it in such incredibly hot and dry year.

Yeah have been watering them, but perhaps not enough then? I planted them over a year ago.....thought they were doing ok......

You reckon it's just a case of not enough water? I'm not convinced the soil they're planted in is the best, although I have used feed and a new layer of compost.

Do I maybe need to just try again? I can now set up some proper automatic watering which might help......
