Jasminoides trachelospermum - one dying, one healthy

Hello,
I have some star jasmine planted in medium sized troughs in my garden (see 1st pic). Strangely, the ones on the outside are in fine health, while the ones in the middle look like they've died (see 2nd and 3rd pic, where you can see the stark difference between the yellow-brown leaves on the left, and the vibrant green on the right). Does anyone have ideas as to what has caused this, whether the "dead" jasmine is salvageable, and how?
Many thanks in advance.
James

They will naturally want to grow into huge plants about 12m x 8m each with a massive root system - and they can't do that so they are struggling to survive.
They need access to lots of nutrients etc and water and a rich soil-based medium to grow in.
They need to be in the ground or a huge container and in full sun to do well.
Also they're not hardy throughout the UK
The containers also seem to have other plants growing in them too which will be taking nutrients that your jasmine needs.
What sort of compost is in the containers?
Do they drain well?
Did you feed them over the summer?
Did the dead one dry out maybe
At then end of the day they won't do well as they are.

In answer to the questions, they've MiracleGro All-Purpose compost in them. I'll try filling with a bit more, although I think I may be somewhat limited in the size of the containers I can provide in that space, and I'll remove the other plants. They do drain well, and I did feed them occasionally over the summer (and watered reasonably frequently, trying to avoid the soil drying out).
I suppose the mystery is why some are doing terribly while the one next to it is doing so well, when I treated them basically all the same. Perhaps the dead ones got some jasmine disease?
I guess I'll cross my fingers and hope they're not actually dead but might return to some degree next year.
In the meantime, would you recommend that I remove the dead leaves?
Ordinary multipurpose compost (MPC) isn't suitable for long-term planting.
MPC is for seeds, cuttings and plants that only last one season.
Anything planted long term in a container needs to be in a soil-based compost.
A mix of John Innes (No 2 or 3 - available from any garden centre) about 50%, 25% MPC and 25% horticultural grit would be an ideal mix for your plants.
I'd recommend changing the compost in Spring as they come into growth. That will help a lot.
Leave the dead leaves, they'll drop by themselves and see how they look in spring.
TJ is a robust plant and not usually susceptible to diseases or pests (other than scale insects if the compost dries out).
When they're growing, feed about once every 1 or 2 weeks - ideally with a high-potash fertilizer (e.g. tomato feed) to encourage flowers.
Long term they won't thrive though in such a small container.

Anyway, thanks for the advice - I'll re-pot in the Spring and hope for the best!
John Innes is more like garden soil and it's heavy, so comes in much smaller bags.
MPC is relatively light and fluffy and comes in 50L or 75L bags.

You can add more compost to the containers, lift the root system and add compost underneath and to the sides (don't just add it on top). I would suggest a free draining mix with soil-based compost (like John Innes) and plenty of grit. Check out the roots. Any signs of vine weevil?
No obvious sign of weevil that I could see.
