Clematis Problems x 2 , Help

Pesky clematis problems time !
First one I repotted C. Red Pearl type 3 into a nice new tall container. Had it for 8 years and it flowers really well. It loved the new container - planted in JI No3 , and looked really healthy . Last week I noticed the flowering had stopped and it looks like this.
Pretty sure its Clematis wilt. Only thing I can do is cut it back to ground level now and it should start to grow back. Any other advice to clear the area of the fungoidal attack ?

1-Clematis Wilt ?


Number two is a C. Niobe , 10 years old . Flowered really really well... until this year ! It now looks very sickly. As photo shows . It used to cover all the fence. I now have this sickly growth. Is this vine weevil ? What can I do to this one now ?

2- Sick Niobe ?

 

Hi Harry, what I would do with your C.Red Pearl is chop it right back, won't do it any harm and give it a good feed with tomato feed.
I would also do the same with your C. Niobe. Is it in a pot ?
What I tend to use for my clematis is 3 parts multi purpose compost to 1 part John Innis No3.

 

Thanks Ian , the Niobe is planted in a border.
I'll cut them right back to ground level tomorrow. Change the top 2" of soil , and give them a good watering. At least now they have about 5 months of growing season to get back on their feet again.

 

I would also give them a couple of handfuls of pelleted chicken manure if you have some, won't do any harm

 

Update , life after Clematis wilt !
The C. Red Pearl that was infected with the fungicidal wilt was cut back on June 11. Just 3 weeks later it's showing new growth
If a Clematis suffers from wilt , is it any less susceptible after being cut back ? Does it gain any immunity ? Is there any preventative treatment that can be applied ?

 

My understanding is that wilt occurs when the plant hasn't been planted deep enough. Looking at your specimen suggests that it has indeed been planted deep enough. Or, maybe I'm confused insofar as ... should it become susceptible to wilt, the fact the roots are planted deep enough gives it a good chance of survival? Think it is the latter.

 

Wilt or not, as soon as I buy a clematis, I will disentangle the branches and layer at least one of them or all of them. Won't do the plant any harm.

 

@alp So layering will in effect give you two plants ?

 

Yes. It's my policy of an heir and a spare. If possible, I layer plants, eg. thornless blackberry, cistus, apple tree (a very young one), jasmines and clematises. All you need to do is bury the branch where there are leaf nodes. Google and you will find it is one of the best way to multiply plants, especially climbers. Have fun and it's very empowering.

 

Oh golly I wish I'd known this sooner, should have Googled it really!
I love clematis but have never had any luck with them, tried them in all different parts of my garden, so gave up planting them. Last month my mother-in-law gave me a Burma Star, It has been lovingly planted into a pot with JI No 3 + compost....fingers crossed it stays alive!

 

Update on my Burma Star..its looking a bit sad...a before and after picture....although there seem to be two 'after' pictures!
