Star Jasmine (trachelospermum jasminoides) - dying

I planted some star jasmine (to hide my neighbour's eyesore of a fence) last year. A couple of plants died very shortly after planting. The photo below is of one of those plants a few days after planting. Note the coppery leaves. The copper colour eliminated all of the green within a couple of days of this, and then the plant keeled over. I replaced the dead plants with new ones.

Within the last week or so, another couple of plants have started showing exactly the same symptom of leaves turning coppery in colour. These are not the ones that replaced dead ones last year.

Does anyone know what the cause is, please? Even better, is it reversible? If so, how?

 

(Apologies for putting the picture in a separate post - the photo didn't want to upload the first three attempts.)

 

I had something similar happen to the one I planted at the more south facing side of a garden arch. I read they need a sheltered position to do well and I'm afraid my own garden was not as sheltered from cold winds as the star jasmine needed to be. Some one else might be able to offer a better insight into the problem and a solution but I think planting something that is a bit hardier might be the only way to go. If the hardier climber got established it might offer some shelter to the star jasmine that has survived and give it a chance to get established. Mine was about a year and a half old when it died but it had not really settled in and started to grow before that and I have tried replacing it with a potato vine that also failed.

 

Thanks, Macraignil. I don't think that that's the cause in my case.The photo above was taken on 5 August 2020. We were then in the middle of a hot spell with warm nights and little wind.

 

Did it get dried out bluepeter?..

 

No. Perhaps ironically, the problems started this year a couple of days after I gave the plants a dose of fertiliser and water.

 

Not the easiest climber to get established from a peat (or peat-substitute) rootball. That damage definitely looks like frost or drought, or either, or both Try trickling plain water very slowly down the stem to thoroughly soak the roots, then wait and see if it sprouts new leaves.

 

Thank you; I'll do that. (I'm not convinced that it's either frost or drought, for reasons set out above. But I've nothing to lose.)
