Red/brown leaves on Star Jasmine

We have what I think is a Trachelospermum jasminoides, planted 5 or 6 years ago in a small bed on a south-facing wall in a small courtyard area.  It has flourished to date, with not much care & attention besides summertime watering.  But I have just noticed that many of its leaves have turned dark red or even brown.  I have tried Googling for the reason/solutions, but can't work out whether it is due to too much water, too little water, lack of nutrients, pests or fungus!  I don't want to make things work by trying the wrong 'cure', so can anyone advise what is most likely the issue here?

In case it is relevant, it is planted next to a Rosa Banksiae Lutea, whose leaves also look rather unhappy (photo included below).

Thanks!

    It's just what they do - noting to worry about and nothing to do with your rose.
    In cold winter some of the leaves turn red. Often they will revert to green, occasionally they don't.
    Just snip off the brown dead bit

    Ps - looks like black spot on your rose - I know it well :)

    A lot of people on here would be delighted if their star jasmine looked that healthy, after this winter!

    Really interested as I (novice gardener) planted this star jasmine last summer and am concerned the leaves are now quite brittle. It’s in a pot on top of a tree stump! I planted it in John Innes number 3 I think (or whatever the nursery recommended). How often should I be feeding with eg Tomorite? And how frequently watering (NE England) at this stage in the year? Many thanks!

    PS My key cause for concern is that the leaves turning red/ yellow can just snap off, which doesn’t seem right!
