Clematis aphids?

hi, I planted a lovely evergreen clematis early last year. It’s come on leaps and bounds, and until very recently looked extremely happy. I noted that a lot of the leaves are yellowing and now turning brown, I’ve also noticed this evening it’s covered in small black and yellow beetles I think these are perhaps aphids? Anything I can do to help the plant?

    My insect identifier app says Harlequin ladybird larva for your second pic. 
  • Ohhhhh that’s interesting - so not aphids. Do we know if they are damaging the plant or is this a coincidence???

    They eat aphids, but are harmful in that they also eat our native ladybirds. A quick Google suggests they don't damage plants.

    I'm not sure they're definitely harlequin ones? But they will help any aphid problem and are good guys as far as your plant is concerned. But yes, if they are harlequins, then they apparently give the native ladybirds STDs!

    It looks like clematis armandii and we have had it growing now for over 20 years and thankfully have had no problems. So sorry that you are having problems with such a great winter plant.

    @Crazybeelady.   Looks very similar to those in Steven's photo.

    Ok yes you may be right @Nel_Staffs In any event @steven.g.garner look at the above thread dedicated to all ladybird larvae!

    The larvae are definitely not doing any damage to your clematis as they are aphid munching machines and not herbivores.

    Being evergreen, your clematis will naturally shed some leaves but not all at once and they will turn colour before falling.   As your clematis has been in situ for some time it my be an idea to give it a generous dollop of slow release fertiliser for clematis, roses or tomatoes as these will have the balance of nutrients needed.   

    If your weather has been dry this winter and/or spring you could also water it well to reduce stress.  Give it 15 litres a t a time, poured slowly so it soaks in round the roots rather than just running off.   You should also do this during any dry periods this summer.

    Possibly a nitrogen problem?
  • Thanks for the help all. I’m actually suffering from a yellowing fatsia and a shrivelled (but only a year old) acer on that side too. I feed pretty regular, and I’m on the watering 100%. Could it all be linked??? @Obelixx @Fairygirl ?
